ASSEMBLY
NOTE: When assembling this transaxle, always use
NEW snap rings.
NOTE: Before assembling transaxle, differential
turning torque must be measured and adjusted.
(Refer to 21 - TRANSMISSION/TRANSAXLE/MANU-
AL/DIFFERENTIAL - ADJUSTMENTS). Differential
turning torque must be measured with geartrain out
of case.
(1) Install input shaft bearing using an arbor press
and remover/installer 8474 (Fig. 47).
(2) Install shift shaft bushing to case using
installer 8475 (Fig. 48).
