Needle roller bearings
Check carefully every needle roller for wear, pitting or spalled areas to determine whether they
are suitable for reuse or replacement. After inspection, dip the needle roller bearings in an oil
bath and then wrap them in a lint free cloth or paper, so as to protect them until they are ready
for assembling.
Oil seals and snap rings
Any oil seal, snap ring, etc. damaged during maintenance, should be replaced by a new one.
Replacement of oil seals and snap rings is cheaper when unit is disassembled than a premature
overhaul to replace these parts in a future time.
An oil leakage through a worn seal may result in failures of other more expensive components
of the transmission. The sealing elements should be handled carefully, particularly during
assembly. Cuts, scratches or rolled up seal lips decrease the sealing efficiency.
WARNING! Snap rings have proper assembling position due to the angle of their
opening ends. The side with shorter opening should be faced towards the outside
to facilitate the installation with pliers.
