Final Reduction Gears; Hypoid Gear - Subaru SVX 1992 Manual

AUTOMATIC TRANSMISSION AND DIFFERENTIAL
(M14o2I 3- 2
Engine power is transmitted from the rear planetary
carrier to the reduction drive shaft and the reduction
drive gear . Power transmission to the front wheels is
then transmitted to the final gear through the reduction
driven gear and drive pinion . Power to the rear wheels
14. Final Reduction Gears
1 . GENERAL
The hypoid drive gear is mounted to the cast iron oil
pump housing by double taper roller bearings . The
hypoid driven gear and the differential are mounted to
the differential case . Both ends rotate and are sup-
ported by taper roller bearings in the converter case .
2. HYPOID GEAR
is transmitted from the transfer clutch hub, welded to
the side of the reduction drive gear, and passes through
the transfer clutch (multi-plate clutch), to the rear drive
shaft - propeller shaft - rear differential - rear wheel .

The front end of the drive pinion shaft is supported by
the double-taper roller bearing on the oil pump housing.
The rear end is supported by two roller bearings on the
transmission case and extension case . The double-
taper roller bearing is preloaded by tightening the lock
nut to a specified torque via the collar . The tooth contact
of the hypoid gear is adjusted by changing the shim
thickness between the double-taper roller bearing
flange and oil pump housing.
The rear end of the drive pinion shaft is spline-fitted to
the reduction driven gear, which is secured with a lock
nut. The external helical spline has some lead, and the
reduction driven gear is force-fitted to this shaft end .
