Leakage Repair
1. Bore-tite
™, a sealant, is used on the outer
diameter of the seals. Substitute seals may not
meet original equipment specifications and
could cause leakage.
2. Clean gearbox exterior to remove all foreign
material. When opening, use care to prevent
foreign material from entering gearbox.
3. To repair horizontal seal, vertical
shaft, or
leakage between cover and gearbox, remove
vent plug
and drain gear lube from box. Re-
move leaking seal and replace (refer to Seal
Installation). Use
care to prevent rolling seal lip
under. Replace gasket between cover and.
gearbox.
Seal Installation
Proper seal installation is important. An improperly
installed seal
will leak and could result in bearing
failure.
1. Clean areas in housing where seal outer diam-
eter seats. Inspect gear shafts. Pay specific
attention to areas where seals seat. Check for
cracks, grooves, nicks or bumps. Replace
housing
or shaft if damage cannot be repaired
by resurfacing with emery cloth.
2. Lubricate seal lip and carefully guide over shaft
using a blunt tool such as a letter opener. Be
careful not to
roll seal lip under. Do not use a
knife as
it will nick and ruin seal.
3. Place seal squarely on housing (spring-loaded
lip toward inside of gearbox). Select a seal
driver, a piece of pipe
or tubing with an OD that
will set on outside edge of seal but will clear
housing.
A driver that is too small will bow seal
cage and ruin seal.
4. Carefully press seal into housing, preventing
distortion to metal seal cage. Seat vertical seal
flush with housing and horizontal seal against
shoulder in housing.
5. Distortion to seal case or damage to seal lip
will
cause seal to leak. Remove and replace seals
damaged in installation.
6. Check for proper vent plug operation and
fill
gearbox with
8 oz. of SAE 90W gear lube.
