  • SERVICING MACHINE AFTER TORQUE CONVERTER OVERHAUL

    The transmission, torque converter, and its alliedhydraulic system are important links in the drive linebetween the engine and the wheels. The proper oper-ation of either unit depends greatly on the conditionand operation of the other; therefore, whenever repairor overhaul of one unit is performed, the balance ofthe system must be considered before the job can beconsidered completed.

    5. On remote mounted torque converters removedrain plug from torque converter and inspectinterior of converter housing, gears, etc. Ifpresence of considerable foreign material isnoted, it will be necessary that converter be re-moved, disassembled and cleaned thoroughly.It is realized this entails extra labor; however ,such labor is a minor cost compared to cost ofdifficulties which can result from presence ofsuch foreign material in the system.

    6,

    After the overhauled or repaired transmission hasbeen installed in the machine, the oil cooler, and con-necting hydraulic system must be thoroughly cleaned.This can be accomplished in several manners and a de-gree of judgment must be exercised as to the methodemployed.

    The following are considered the minimum steps tobe taken:

    Drain entire system thoroughly.

    2. Disconnect and clean all hydraulic lines. Wherefeasible, hydraulic lines should be removed frommachine for cleaning.

    3. Replace oil filter elements, cleaning out filtercases thoroughly.

    4. The oil cooler must be thoroughly cleaned. Thecooler should be "back flushed" with oil andcompressed air until all foreign material has beenremoved. Flushing in direction of normal oil flowwill not adequately clean the cooler. If neces-sary, cooler assembly should be removed frommachine for cleaning, using oil, compressed airand steam cleaner for that purpose. DO NOTuse flushing compounds for cleaning purposes.

    Reassemble all components and use only typeoil recommended in lubrication section. Filltransmission through filler opening until fluidcomes up to LOW mark on transmission dipstick.NOTE: If the dipstick is not accessible oil levelcheck plugs are provided.

    Remove LOWER check plug, fill until oil runsfrom LOWER oil hole. Replace filler and levelplug.

    Run engine two minutes at 500-600 RPM toprime torque converter and hydraulic lines. Re-check level of fluid in transmission with enginerunning at idle (500-600 RPM).

    Add quantity necessary to bring fluid levelto LOW mark on dipstick or runs freely fromLOWER oil level check plug hole. Install oillevel plug or dipstick. Recheck with hot oil(180-200 F.) [82, 2-93, 3 C].

    Bring oil level to FULL mark on dipstick orruns freely from UPPER oil level plug.

    7. Recheck all drain plugs, lines, connections, etc.,for leaks and tighten where necessary.

    CONVERTER CHARGE PUMP REPLACEMENT AND PRIMING PROCEDURE

    1. The cause for pump failure must be found and corrected before a replacement pump is installed. Check all of the hoses,tubes, "0" rings, adaptors and split flanges.

    2. Replace any collapsed or damaged hoses, damaged split flange "0" rings, tube "0" rings and adaptors.

    3. After all checks have been made and corrections completed install the pump.

    4. See filling instructions in paragraph 6 above.

    5. Start the engine. Run the engine at low idle for two minutes, watch the clutch pressure gage and listen for cavitation ofthe pump.

    6. If the pressure does not come up, check the oil level and bleed off air from system as follows.

    7. To bleed off the air from the system, loosen the pressure gage line at the pressure regulating valve or loosen the pressurehose at the oil filter or pressure regulating valve. Crank the engine over until the air is displaced with oil. DO NOT STARTTHE ENGINE.

    8. If bleeding the lines does not correct the problem it may become necessary to prime the pump. Disconnect the suctionhose or pressure hose, whichever is higher, and fill the port with transmission oil, reconnect the hose and tighten.

    9. Start the engine and check pressure.

    10. Recheck oil level with hot oil (180-200F) with engine at idle. Add oil as necessary to bring oil level to full mark.

  • CLEANING AND INSPECTION

    ICLEANING

    Clean all parts thoroughly using solvent type clean-ing fluid. It is recommended that parts be immersedin cleaning fluid and moved up and down slowly untilall old lubricant and foreign material is dissolved andparts are thoroughly cleaned.

    CAUTION: Care should be exercised to avoid skinrashes, fire hazards and inhalation of vapors whenusing solvent type cleaners.

    BearingsRemove bearings from cleaning fluid and strike flat

    against a block of wood to dislodge solidified particlesof lubricant. Immerse again in cleaning fluid to flushout particles. Repeat above operation until bearingsare thoroughly clean. Dry bearings using moisture-free compressed air. Be careful to direct air streamacross bearing to avoid spinning. Do not spin bearingswhen drying. Bearings may be rotated slowly by handto facilitate drying process.

    Figure 31Remove pressure regulator valve assembly. Use

    caution as not to lose safety valve plunger or spring(See arrow).

    HousingsClean interior and exterior of housings, bearing caps,

    etc., thoroughly. Cast parts may be cleaned in hotsolution tanks with mild alkali solutions providing theseparts do not have ground or polished surfaces. Partsshould remain in solution long enough to be thorough-ly cleaned and heated. This will aid the evaporation ofthe cleaning solution and rinse water. Parts cleanedin solution tanks must be thoroughly rinsed with cleanwater to remove all traces of alkali. Cast parts mayalso be cleaned with steam cleaner.

    CAUTION: Care should be exercised to avoid in-halation of vapors and skin rashes when using alkalicleaners.

    All parts cleaned must be thoroughly dried immedi.ately by using moisture-free compressed air or soft,iintless absorbent wiping rags free of abrasive materi-als such as metal filings, contaminated oil or lappingcompound.

    INSPECTION

    The importance of careful and thorough inspectionof all parts cannot be overstressed. Replacement ofall parts showing indication of wear or stress will elim-inate costly and avoidable failures at a later date.

    Bearings:Carefully inspect all rollers, cages and cups for wear,

    chipping or nicks to determine fitne~s of bearings forfurther use. Do not replace a bearing cone or cupindividually without replacing the mating cup or coneat the same time. After inspection, dip bearings inrecommended type Automatic Transmission Fluid andwrap in clean lintless cloth or paper to protect themuntil installed.

    REASSEMBL Y OF TORQUE CONVERTER

    Instructions given below on reassembly of compo-nents are given in the sequence that must be followedin rebuilding.

    Oil Seals, Gaskets, Etc.

    Replacement of spring load oil seals, "0" rings,metal sealing rings, gaskets and snap rings is moreeconomical when unit is disassembled than prematureoverhaul to replace these parts at a future time. Fur-ther loss of lubricant through a worn seal may resultin failure of other more expensive parts of the assem-bly. Sealing members should be handled carefully,particularly when being installed. Cutting, scratching,or curling under of lip of seal seriously impairs itsefficiency. Apply a thin coat of Permatex No.2 onthe outer diameter of the oil seal to assure an oil tightfit into the retainer. When assembling new metal typesealing rings, same should be lubricated with coat ofchassis grease to stabilize rings in their grooves forease of assembly of mating members. lubricate all"0" rings and seals with recon-:mended type AutomaticTransmission Fluid before assembly.

    Gears and Shafts

    If magna-flux process is available, use process tocheck parts. Examine teeth on all gears carefully forwear, pitting, chipping, nicks, cracks or scores. If gearteeth show spots where case hardening is worn throughor cracked, replace with new gear. Small nicks maybe removed with suitable hone. Inspect shafts andquills to make certain they are not sprung, bent, orsplines twisted, and that shafts are true.

    RING GEAR INSTALLATION PROCEDURE)J

    1 Remove all burrs from flywheel mounting face and pilot bores. Clean the torque converter ring gear flywheelmounting surface and the ring gear screw tapped holes with solvent. Dry thoroughly, being certain ring gearscrew holes are dry and clean.

    I

    I Check engine flywheel and housing or housing adaptor for conformance to standard S.A.E. No.3 -SAEJ927 and J1033 tolerance specifications for pilot bores size, pilot bores eccentricities and mounting facedeviations. Refer to CLARK-HURTH form number 802563 for measuring procedures.

    2.

    3. Measure and record engine crankshaft and end play.

    Install torque converter ring gear as shown.4.

    NOTE: Assembly of the ring gear must be completed within a fifteen minuteperiod from start of screw installation. The screws are prepared with an epoxycoating which begins to harden after installation in the flywheel mounting holes. If nottightened to proper torque within the fifteen minute period insufficient screw clampingtension will result.

    I 5. Install backing ring and sixteen (16) special screws to approximately .06 inch [1.5 mm] of seated position. It ispermissible to use a power wrench for this installation phase. With a calibrated torque wrench tighten screws 38to 42 pounds feet of torque [51,6- 56,9 N.m].

    To obtain maximum effectiveness of the special screw's locking feature, a minimum time period after screwinstallation of twelve (12) hours is suggested before engine start-up.

    I The special screw is to be used for ONE installation only. If the screw is removed for any reason it MUST BEREPLACED. It is recommended that the epoxy left in the flywheel hole be removed with the proper tap andcleaned with solvent. Dry hole thoroughly and use a NEW screw for re-installation.

    6. Assemble torque converter to engine flywheel by sliding converter into position by hand before fastening hous-ing attachment screws. This may require more than one trial to match the drive gear teeth. Pulling the convert-er into position with housing attachment bolts is not recommended.

    Measure engine crankshaft end play after assembly of torque converter. This value must be within onethousandth (.001) of an inch [0,0254 mm] of end play recorded (line 3) before assembly of torqueconverter.
