Checking and replacing parts
Thoroughly clean all the hub parts. Check all the parts for wear,
deformation or other damage.
Check needle rollers, gears and all bearing surfaces. If a planetary
gears is damaged, all the planetary gear journals and rollers must
also be replaced at the same time since they are matched within
the same tolerance class for optimally smooth operation. Also
check the contact surface for the seal, on the wear ring and on
the drive shaft. Replace damaged parts.
WARNING:
With damage to the hub reduction, the final drive must
always be removed, checked and cleaned. The entire rear
axle casing must be thoroughly clean on the inside even the
space at the outer ends of the casing.
Concerning removal and installation of the drive, refer to the
service manual for the relevant drive in question.
Assembly
Grease the rollers of the planetary gears and assemble them in
the gears, with the spacer sleeve.
NOTE
: each gear must have 38 needle rollers.
Place the planetary gears and thrust washers in the hub casing,
aligning with the journal pin bore, and ensuring that the brass
washers are in contact with the hub casing. Fit new O-rings on
the journal pins and grease thoroughly with GLEITMO 805 grease.
Press in the journal pins using a drift. The pins should be pressed
in sufficiently to allow the retaining circlips to be fitted inside.
(Fig. 17) Fit the retaining circlips on the journal pins. (Fig. 18)
Lubricate and press into position by hand a new inner hub seal.
Refit a new outer O-ring on the hub using grease GLEITMO 805
as lubricant (fig. 19). Thoroughly grease (ALVANIA RL 3) the
spindle bearing journals and locate the hub in position on the
spindle. Locate the ring gear carrier into position.
