F i g . 7 F - 8 2 Checking Converter End Clearance
CONVERTER END PLAY CHECK
1. Fully release collet of tool J 21371 by turning
screw clockwise.
6. Assemble pump body and cover. Install five
retaining bolts, but do not tighten. Align pump body
and cover with tool J 21368 (Fig. 7F-81). Tighten
bolts to 20 lb. ft. torque. Remove tool J 21368.
CONVERTER LEAK TEST
1. Install tool J 21369 and tighten.
2. F i l l converter with air at a pressure of 80 psi.
3. Submerge in water and check for leaks.

TRANSMISSION REASSEMBLY
GENERAL
Before starting to assemble transmission, make
certain that all parts are absolutely clean. Keep
hands and tools clean to avoid getting dirt into as­
sembly. If work is stopped before assembly is
completed, cover all openings with clean cloths.
Lightly coat all moving parts with transmission
oil before Installation. Thrust washers may be held
in place with petrolatum sparingly applied.
J 21368
Do not take a chance on used gaskets and seals -
use new ones to avoid oil leaks.
Use care to avoid making nicks or burrs on parts,
particularly at bearing surfaces and surfaces where
gaskets are used.
