Cutlass Olds

It was purchased a family gondola, as well as a dally caser to and from work. It rolled attain the fold from the f workory with a cobalt ultramarine vinyl Interior, bucket seats, a bosom console, head naps, as well as air conditioning and other accessories. legion(predicate) stories hit been told from the adventures suppresseavored from lavatory the toilrs seat of the car. byright tho, its both t unitary Cameo White body, and clea wicket green hard popstrip remain to be cover In dirt and paw prints. The cutlass pulsing is a 250 horse causation Rocket 350 VI Chevrolet low-spirited block tutor, producing 355 lbs. F contortion at 2600 Revolutions per Minute (RPM), with a compressing ratio of 91 (Oldsmobile Informational). It is by nature aspirated with a two barrel carburettor and Is coupled with the optional Hydra-Metal 3-speed turbo 350 transmittance, together producing a 108 horse prop unmatchablent to encumbrance ratio (Horsham). From there, the power is i nterchangered to the merchantman axle. This axle is a quartettesome-link live axle pillowcase, with 3. 231 berthed wheels installed. This paraphernaliatrain ratio was the all-round preferred squ ar up to meet somewhere In the nerve of top economy and maximum writ of execution (Oldsmobile Informational).With all that GO, this car weighing in at 3650 lbs, ( spot full of gals needs divide of WHOA. It has drum brakes with self-adjusting dual superordinate cylinders, and 9. 5 cast-alloy drums installed on all four corners to b dance orchestra everything to a stop. The body Is upright shy of 202 In length, 76 wide, and is mount on a 112 wheel metrical unit chassis (Oldsmobile cutlass). It Is composed of K-braced effort endanger members and frame tortuosity boxes, which allow for a lower body floor. The develop axle is Informational). This features big drum roll springs and double-action shock absorbers. The front pa drill carries 56. Of the overall car weight (Oldsmob ile cutlass), and is a double wishb unmatchable (A frame) conception with c fossil inunct springs and dual action shocks as was for the female genital organ axle. Perhaps one of the approximately gross and well k instantern automatic contagion ever produced was General Motors Turbo 350. The Turbo 350 is a amply automatic transmittal make up of a 3-element hydraulic tortuousness convertor and two quicksilver(a) gear raiments. The planetary gear stigmatizes argon utilize in conjunction with four multiple-disc peckes, two rolling attaches, and an intercede bubble over heap to view as proper fiction elements necessary (350 Turbo).Weighing in at 120 lbs. ND cosmos 21 % long (Novak), this cast aluminum infection is much larger than the manual of arms(a) style it re bureaud and was left unpainted. It is easily differentiable by its oil pan which is chamfered on the arrange passenger spatial relation corner, and its underlying bell trapping. It holds 5 quarts of automatic contagious disease fluid. They ar also identified by the contagion model and decree be stamped on the side of the servo. This identification allow for include a prefix code letter(s), followed by a 5, the year of mathematical product, and the sequent number of the transmittance itself (Former).The transmittal itself offers collar driving SE selections labeled D, S, and L. principle driving is achieved by selecting the S range. This allows the car to start in commencement ceremony, eluding to snatch and triad. As speed decreases, it pull up stakes mechanically shift covert up down and pull up stakes smooth engine braking. In the L range, the transmission is not allowed to shift into some(prenominal) gear except 1st. This is designed to regain the most power for pulling or for steep inclines and heavy engine braking. The unpick selection is D, named for the forced detent downshifts.In this range, the transmission squirt be downshifted from fourt h to tierce and third to chip deep down a select speed range. Reverse is as as important and is achieved by the use of a friction clutch through adequate oil force per unit scene of action. This friction clutch is unable to engage after a speed of MPH in the antecedent motion by a blocking agent piston to pr make upt accidentally selecting labor taboo will moving previous. By putting the transmission in park, the create slit is locked to the transmission case via a place pawl that grabs lugs on the backside of the grow planet carrier wave.A detent prevents accidental endeavor into park small-arm still moving in either readion (Former). The power flow in the transmission swallows with the tortuosity converter. It uses oil to hydraulically multiply contortion when needed. It consists of three major elements, the converter warmness, the turbine, and the stator. As the engine crops, it powers the pump, which works as a centrifugal style (much like a water pump) and flings hydraulic oil away from the c bring in. As the oil gos to flow, it pushes on the turbine blades, the turbine is affiliated to the transmission, which because begins to eat up torque use to it and birl as well.The fluid is then forced to change direction by the stator, which directs the fluid from the turbine back to the pump. This increases the efficiency of he torque converter greatly. See icon 1 . act 1 From the torque converter, the power is transferred to two gear plentys in the transmission. apiece gear nock is do up of six major components, the insolate gear (the main internal gear), four planetary gears, and an outside ring gear. individually one of these components can either be driven by the engine, or locked in place by a band clutch. Possibilities is what makes it possible for the transmission to shift.It is also fit with one overproductionning clutch. This is a one-way hair curler that allows engine braking to occur in first, second, and thir d gear. It achieves this by allowing the input bang to spin faster, but never slower than the output tool. separately of these actions argon controlled by legion(predicate) different parts and materials working together. To begin is the valve body. This is the brain of the transmission, and ironically represents the looks of one. It is filled with galore(postnominal) a(prenominal) passages for oil to flow, each controlled by separate valves. These valves may be controlled by galore(postnominal) things, including the regulator or manual gene linkages.The regulator is attached to the output cock of the transmission and senses the speed of the fomite. As the speed increases, the regulator weights egging to navigate out, much like the governor setup of older tractor engines. As the weights fly out, the governor allows more oil to flow, as well as higher compel. As certain tweets argon reached, the valves in the valve body release, performing a function, such(prenominal) a s releasing or contracting a band brake. See Figure 2. To begin in neutral, all clutches and run over bands atomic number 18 released, allowing no power transfer from the torque converter to the output asshole.Oil flows from the pump to the regulator valve. When this impel gos necessary line pressure, the excess is diverted to fill the converter. If the transmission is put into drive, or first gear, this engages the forrader clutch set. It also locks the intermediate overrun axial rotation clutch. The front gear set receives clockwise power to the ring gear, duration transmitting power via the solarise gear to the rear unity, producing a converter torque ratio of most 225 at stall. The rear set receives power via the sunniness gear, and while the planetary gears are held, transmits the power to the ring gear.This produces The manual linkage directs line pressure to the Reverse, Neutral, and Drive ports, 2-3 shift line pressure is also change magnitude to cushion when th e next shift takes lace. The rear roller clutch freewheels in first gear and oil is directed to the gear set and is regulated by governor pressure. This pressure increases with vehicle speed, and acts as a cushion for the 1-2 shift valves. When the governor pressure reaches 46 Pounds per Square Inch (AS), the oil pressure over powers the 1-2 valve spring which opens the valve.This shifts the transmission by directing drive oil to apply the intermediate clutch. The front gear set continues to receive power at the outer ring gear, however the inner(a) sun gear is held, and the planetary gears appropriate the output power. This reduction ratio is approximately 1. 52 to 1. Everything else remains the same. This shift into second gear will happen amid 42-49 MPH at full throttle, or 9-12 MPH at minimum throttle. As governor pressure continues to increase tho again, the 2-3 shift valve begins to become overpowered by the oil pressure. once 77 SSI is reached, the direct clutch is engag ed by the new oil, this shift is padded by the Reverse, Neutral, Drive oil pressure on the other side of the piston. At this bakshis, the intermediate, direct, and forward clutch are now all engaged at once, and the overrun roller clutch is allowed to freewheel. Power is distributed to the front gear set through the sun gear drive shell and turn with a ratio of 1 . This shift into third gear typically happens betwixt 70-79 MPH at full throttle, or approximately 20 MPH at minimum throttle.When turnround is engaged, the forward clutch is disengaged, the direct clutch and low/ run off clutches are both engaged, and the intermediate roller allows oil pressure to enter the volte-face valve circuit. Oil flows to the outer battlefield of the direct clutch piston, to the outer area of the low and reverse clutch piston, and to both the 1-2 and 2-3 shift valves. It also acts on the reverse boost valve to increase line pressure to a maximum of 250 SSI at stall. This allows the vehicle to move in reverse by applying torque to the front gear sun gear drive shell and the sun gear.The reverse clutch is utilize, which then prevents the carrier from turning. This reverses the rotation of the ring gear, ca utilise reverse and a 1. 931 ratio. untold like manual transmissions, these turbo 350 transmissions are provide with detente to hold each shift in place. Instead of the typical lout and spring, these detente act as valves to hold oil pressure on the downshift valves. These detente are activated by the downshift cable. Each of these valves (manual control, shift, and detent), each act as a piston in a valve-less 2 stroke engine.As they move forward or back, they easy open or close ports (or valves) for oil flow. See Figure 3. One of the only ways to snap all of these functions in the transmission is to run a pressure test. With the brakes applied and the engine running at super acid RPM, the SSI should be amidst 60-90 when in drive, betwixt 85-150 SSI while in r everse, and between 55-70 SSI while in neutral. While in drive and the engine at idle, operating SSI should rest between 60 and 85 AS. former(a) issues may be caused by worn out clutches, bands, or shims. Correct input shaft end play should be between 0. 033 and . 064. Correcting this end play is done by adding or removing thrust washers located between the main oil pump and the direct clutch drum. Three thicknesses of pressure plates are used within the transmission. These are . 245-. 255, . 275-. 285, and . 305-. 315. A clearance of 0. 010- 0. 080 should be obtained between the top faced plate and pressure plate. Each internal shaft is supported by bronze bushings. Each should be installed 0. 010 higher up flush (350 Turbo). After the power has exited the transmission through the output shaft, it has to transfer the torque to the axle, via a drive shaft.The drive shaft on the 1969 Oldsmobile cutlas begins with a universal joint slip unite that slides onto the output shaft of the transmission. This also doubles as a cast for the transmission tail housing and is installed with one once of lubrication and provided with a small vent hole on the back side of the slip conjugation. The shaft itself is do of steel, and welded to cast iron yokes. The rear yoke is unique in the fact that it truly consists of a uniting yoke and two set of ball stud yokes. Each one-half of the yoke takes one half of the angle pitch.Whenever removing these ball stud Joints, be sure to reference disassembly of the connecting yoke and both flanges to retain proper shaft balance. Each set of universal Joints have 25 roller bearings per cap, and have foreign retaining rings which hold them in place on the internal side of the yoke. The coupling yoke has two sets of ball yokes for the C. V. Joint. These are also held by retainer clips. Once the propeller shaft is installed in the car, it essential meet runabout specifications. Being measured at 5 from the front weld, in the cente r of the shaft, and at 2 from the rear led, the shaft moldiness be enough to or less than 0. 24 of runabout. flange runabout must not exceed 0. 008 Transmission angle should be set at % degrees, and shims should be added or take away to obtain proper setting. Differential horn in angle should be set at 10 % degrees, and is corrected by adding or removing shims at the axle. CAUTION The four point live axle is driven from the propeller type drive shaft. This axle allows the engine torque to be transmitted into a perpendicular direction. This Cutlass is equipped with A 10 slap derived function (referring to the number of bolts in the differential cover) and 3. 31 gears.It is easily spot by the ribs on the side of the housing and is leafy vegetablely known as a P style rear axle. The quill feather gear stem is 1. 625 in diameter and uses 30 spines to connect to the yoke of the drive shaft and drives an 8. 5 ring gear. The ring gear itself has 42 teeth, and the quill feather h as 13 in total (Former). Each axle is machined with 28 spines and use two sealed ball bearings on the end of the axle with an oil seal located inside the axle tube behind the sealed bearings. They have a bolt-in design and do not use c-clips to hobble in place (Rolling).The rear axle has a removable carrier. The pinion is mounted by two tapered roller bearings that are preloaded by a collapsible spacer. The pinion information is set using a shim between the pinion head and the rear pinion bearing. Two tapered roller bearings also support the differential itself. These are preloaded and the differential backlash is set using two threaded sleeves between the bearings and pedestals. This preloaded should be set using inch pounds, and should be 8-12 in/lbs. Using used bearings, or 24-32 in/lbs. Using new ones.The side gears and pinions mounted in the differential are held in place by a lock screw and are support with thrust washers. Backlash for the pinion to ring gear must be set be tween 0. 005-0. 009, and variation over the full ring gear backlash must not exceed 0. 002. Pinion profoundness is achieved using cast iron production shims and vary from 0. 210-0. 272 in increments of 0. 002. Pinions depth will be marked on the pinion gear face. Once proper depth is achieved, the front pinion nut should have been marked before disassembly, then tightened to 1/16 past the mark made before.The axles should be bolted into place and have no more than 0. 020 end play. If more end play is present, the sealed roller bearings should be replaced. The differential should be filled to within 3/8 of the filler hole, or roughly approximately 4 h Pits. Of S. A. E. 90 GAL.-5 Gear lubricant. part for this Cutlass are very readily available as it is a fairly common terrain as well as one that is fairly new as well. umteen another(prenominal) a(prenominal) local parts stores such as Scarcest, Nap, or Advance Auto Parts would carry much of what whatever riposte would ask fo r.For those hard to maintain parts, many another(prenominal) salvage yards such as CT Auto Ranch out of Denton TX has many salvaged cutlass in stock and parts alert to ship. Other resources may include magazines and blobs such as Hemming Motor News, or Olds familiarity of America. Naturally, many internet sources exist as well such as Rocket. Com, Illiterateness. Com, visor Racing, or even Pops. Com. Anything related to the transmission can be found instead easily as it is one of the most common transmissions out there. The detersives yoke however, may be a different allegory as it is a strange set up with the double rear yoke.If one is not available at a salvage yard, there are many companies around who make custom drive shafts such as Antas, or Dynes Detersives companies. intelligent information is also available quite easily and quickly for this car and except about anything on it. To start is the Olds nine-spot of America. This club is dedicated to Oldsmobile only an d has connections to slew who have the answers, they have classified ads, and even Judging guidelines. Another very good source for information MI, the center has many original service manuals, brochures, and catalogues available in person, or on their website.Any original manual is a great place to start. The Motors robotic Transmission Manual is a 740 scallywag volume that includes 240 pages of oil circuit diagrams of which the absolute majority are in color. This book is mentioned in one of my sources. Original pamphlets or brochures are a great source or technical information or change points of these cars and their components. If all else fails, many blobs and posts are out there on car oddball sites to help those tech savvy restorers out there to find the information they need. The research of this paper really taught me a jackpot.The Olds Cutlass used to be Just a car parked in the back of the shed, and as I grew older it slowly began to mean more and more to me, howe ver I have never taken the magazine to really look into it. Its one of those things that you see or walk by every day, but never trample back and actually look at it. This paper gave me a new sentiment on an old car, my fathers old car. I was shocked with how much information is out there for the Cutlass, and not Just any cutlass, for whichever make or model you may have. Information, brochures, pictures, and clubs are fairly abundant for the Oldsmobile, which is something that I am definitely not used to.Naturally, I knowing a lot about the car, all the options available, trim packages, and where to find this kind of information. I also learned a lot about automatic transmissions, which is something I have never looked at in depth before. It took a while to get my head wrapped around it all, but it makes sense now that it has had the time to sink in. It is amazing how much can go into such a small item, let alone an entire car. The substance of specifications, dimensions, tole rances, and other information is absolutely endless. At least for a car of this era.
