collar. Then pilot the reverse idler shaft into the

extension housing permitting the extension to slide

onto the transmission case.

19. Install 6 extension and retainer-to-case attaching

bolts. Torque upper 3 bolts and lower 3 bolts to

specification.

20. Push or pull reverse shifter shaft to line up groove

in the shaft with the holes in the boss and drive in

the lock pin. Install shifter lever.

Press bearing onto main drive gear (snap ring

groove to front) and into case until several main

drive gear retaining nut threads are exposed.

Lock transmission up by shifting into two gears.

Install main drive gear retaining nut on the gear

shaft and draw it up tight using Tool J-0933. Be

sure bearing fully seats against shoulder on gear.

Torque retaining nut to 40 ft. lbs. and lock in place

by staking securely into main drive gear shaft hole

with a center punch. Care must be used to avoid

damaging the threads on the shaft.

Install the main drive gear bearing retainer, gasket,

four attaching bolts and (2) strip bolt lock retainers,

using a suitable sealer on bolts. Torque to

specification.

Shift mainshaft 3-4 sliding clutch sleeve into

neutral position and 1-2 sliding clutch sleeve into

second gear (forward) detent position. Shift side

cover 3-4 shifter lever into neutral detent and 1-2

shifter lever into second gear detent position.

25. Install side cover gasket and carefully position side

cover into plate. There is a dowel pin in the cover to

assure proper alignment with the case. Install

attaching bolts and tighten evenly to avoid side

cover distortion. Torque to specification.

DISASSEMBLY OF TRANSMISSION

Refer to Figures IQ and 2Q

1. Mount transmi sion in suitable holding fixture and

remove cap screws attaching transmission cover

assembly to transmission case. If required, insert

two 5/16 x 18 screws in cover flange threaded holes

and turn evenly to raise cover dowel pins from case.

NOTE: Move reverse shifter fork so that

reverse idler gear is partially engaged before

attempting to remove cover. Forks must be

positioned so rear edge of the slot in the

reverse fork is in line with the front edge of

the slot in the forward forks as viewed

through tower opening.

2. Place transmission in two gears at once to lock

gears. Remove the universal joint flange nut,

universal joint front flange and brake drum

assembly.

NOTE: On models equipped with 4-wheel

drive transfer case, use Tool J- 23070 to

remove mainshaft rear lock nut (fig. 26Q).
