DIFFERENTIAL
The differential of the
JH3-051 gearbox is the simple type (with two satellites and two planetary
wheels, one of which making a common body with the tulip of the planetary transmission).
This differential is supported in the clutch – differential crankcase by means of two cylindrical
bearings equipped with balls of various sizes.
The two bearings are pressed in the clutch – differential crankcase.
The crown of the main transmission is assembled by hooping, on the differential crankcase.
DIFFERENTIAL DISMOUNTING
This operation is to be performed after separating the crankcases.
The zero ring (1) is removed from the right planetary shaft, then by means of a pins extractor
and a hammer, the sealing gasket (2) is gently hit in order to make it pivoting.
The oil seal ring is carefully pulled along the grooved part of the planetary pinion in order not
to deteriorate t he grooves.
