Torque converter reassembly
a.
General. Reassembly of torque converter requires a clean, dust free location. Insure that work bench and all
converter parts are thoroughly clean and dry. During reassembly some parts will be soaked or coated with diesel fuel
(torque converter fluid); DO NOT use more fluid than required and wipe up any spills.
CAUTION
Do not attempt to repair parts in work area where you are assembling torque converter. Sanding
or polishing nicks and burrs will leave fine metal dust and grit in work area which will require
recleaning all parts and work area. Small amounts of this type of foreign material can seriously
damage converter.
b.
During reassembly reinspect each part for burrs, nicks or similar damage. Refer to paragraph 6-35 for repair or
replacement of damaged parts.
c.
Refer to Figure 6-35 and assembly fluid seal assemblies as follows:

During this assembly, be sure rubber elements and washers are properly seated. Apply a film of
motor oil to sealing surfaces of steel nose piece and carbon mating ring for lubrication and
protection during reassembly of converter.
