Section XII. Torque Converter Disassembly, Inspection and Repair
Torque converter disassembly
General. The torque converter is a highly reliable and relatively simple power transmission device. However,
the various internal parts of the torque converter are built to very close tolerances and minor damage to these parts can
seriously reduce the converter's efficiency. Before attempting any repair of the torque converter you must have a clean,
dust-free area in which to work and the converter assembly must be absolutely clean.
Remove torque converter form winch sub frame.
Cap or plug all fluid openings on winch and on torque converter and thoroughly clean entire assembly.
Remove clutch assembly as described in.
Clean, inspect and repair the clutch assembly in an area removed from torque converter so that soot and dirt
from clutch will not enter any part of converter during maintenance.
Remove chain drive assembly as follows: Perform any required maintenance in an area removed from the
Detach upper grease hose and lower rear seal drain line at ends which pass through drain housing.
Remove nuts and lockwashers that retain chain housing to converter housing.
Remove chain housing with output shaft.
Remove output shaft by removing bearing retainer, shaft lock nut and washer.
Press shaft out of shaft bearing.
Clean any residual soot, dirt, grease and foreign material off the converter housing where it
attaches to the chain drive and clutch assemblies. Any foreign matter introduced into the
converter can cause excessive wear to the close fitting parts and plug small orifices. Serious
damage to the converter can result if special cleanliness is not maintained.
Refer to Figure 6-34 and disassemble Impeller Assembly as follows:
Press input shaft and shaft bearing out of sliding sleeve carrier.
Remove impeller locknut, lockwasher, and spacer.
Press impeller out of impeller bearing
Remove six socket head capscrews retaining seal carrier to endplate and remove seal assembly.
