Remove turbine wheel from converter housing as follows:
Remove turbine wheel bearing retainer and remove turbine wheel lock nut and lock washer.
Press turbine wheel and shaft out of converter housing through turbine wheel bearing.
Remove six socket head capscrews retaining seal carrier (Figure 6-35) to converter housing and remove
seal assembly. Seal carrier may be removed from converter housing by tapping on the opposite side of turbine wheel
bearing outer race.
Remove turbine wheel bearing.
If converter is being disassembled for reasons other than seal repair, and it is intended to
reassemble converter using same seal assemblies and carbon mating rings, extreme care must be
taken to keep sealing surfaces of steel nose piece and carbon mating ring free from all dirt and
Refer to Figure 6-35 and disassemble fluid seal assemblies as follows:
Remove two screws and clips retaining steel nose piece to seal carrier and remove nose piece.
Remove eight coil springs and retaining washer and rubber element with garter spring.
Remove lip-type grease and oil seal.
If seals or carbon rings show excessive wear or have been damaged during disassembly replace
during reassembly. Close tolerances of converter require near perfect sealing surfaces.
