Installing
Installation is the reverse of removal, note the following:
Notes: - Pull off drive flange together with housing.
The threaded bores in the drive flanges of the transmission and the
final drive should be cleaned of all locking compound residue after
driveshaft has been removed. Otherwise there is a risk of seizing the
bolt when tightening and break off at next disassembly. Clean by using a thread tap.Replace seals between driveshaft and drive flange (Remove
protective film and bond seal to drive flange. Adhesive bond surface
must be free of grease. Always replace self-locking driveshaft bolts.
- If driveshaft has factory color marking, determine radial deviation on
flange/driveshaft Page 39
-77
and align color marking on driveshaft
to new color marking on drive flange.
