Lubrication Information
1. Do not let excess grease collect on or around parts,
particularly when operating in sandy areas.
2. See Figure 14 for lubrication points and frequency
of lubrication based on normal operating conditions.
Severe or unusual conditions may require more frequent
lubrication.
3. Use a lithium grease of #2 consistency with a MOLY
(molybdenum disulfide) additive for all locations unless
otherwise noted. Be sure to clean fittings thoroughly before
attaching grease gun. Two good pumps of most guns is
sufficient when the lubrication schedule is followed.
PTO Drive Lines
Periodically check the yokes on front PTO. Make sure the
bolts and nuts are tight and the yoke is not moving on
the shaft. PTO shafts and U-joints should be sparingly
lubricated monthly.
Qualified Technician Maintenance
Gearbox Lubrication
The gearboxes should be checked quarterly to be sure
that the oil level is maintained at half full. Use plug located
halfway up back face of gearbox to check/fill oil. A high
quality gear oil with a viscosity index of 80W or 90W and an
API service rating of GL-4 or -5 is recommended for use
in the gearboxes. Oil should be changed after the first 30
hours or 30 days of operating; then checked regularly for
leakage. In the case of seasonal usage, it is best to change
the oil at the end of the season to remove moisture and
corrosive contaminants.
Use a 5/16" Allen wrench to remove fill plug.
Bearing Lubrication
Lubrication of the bearings will vary considerably with
conditions. As a rule, bearings should be underlubricated
rather than over-lubricated. Over-lubrication can cause
seals to blow out.
NOTICE
Replacement bearings should be only high quality
original equipment bearings for longer life.
Install new complete bearing housing if needed or just
replace the bearing insert. The shafts should be straight,
free of burrs, and up to size. If shaft is worn, replace it prior
to completing assembly.
Bearing And Shaft Service
1. Place tiller on level, dry surface and block tiller. (See
Blocking Method).
2. Support rotor shaft with blocking or strap so that bearing
assembly does not support weight of rotor.
3. Remove 1/2" flange lock nuts from bearing cover, gasket
and external snap ring from shaft.
4. End plate may be removed from frame to repair or replace
bearing assembly by removing top two 1/2" flange lock
nuts and bolts.
5. Replace inside gasket, bearing assembly, bearing, internal
snap ring, or double lip seal as needed.
6. Install bearing assembly on shaft locking into place with
external snap ring.
7. Install inside gasket and end plate onto bearing and main
frame with top two 1/2" bolts and nuts and bolts in bearing
assembly.
8. Place outside gasket and bearing cover over end- plate and
bolts with 1/2" flange lock nuts tightened into place.
9. Add grease into bearing cavity so that it is half filled.
(Approximately 40 pumps)
