Lubrication; Pto Drive Lines; Qualified Technician Maintenance - Woods RT42.30 Operator's Manual

LUBRICATION INFORMATION
1. Do not let excess grease collect on or around parts,
particularly when operating in sandy areas.
2. See Figure 13 for lubrication points and frequency
of lubrication based on normal operating conditions.
Severe or unusual conditions may require more fre-
quent 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 lubrica-
tion 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 spar-
ingly 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 oper-
ating; 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 under-lubri-
cated rather than over-lubricated. Over-lubrication can
cause seals to blow out.
NOTICE
■ Replacement bearings should be only high qual-
ity 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)
Driveline Lubrication
1. Lubricate the driveline slip joint every 8 hours of op-
eration. Failure to maintain proper lubrication could
result in damage to u-joints, gearbox, and driveline.
2. Lower tiller to ground, disconnect driveline from
tractor PTO shaft, and slide halves apart. Do not
disconnect the halves from each other.
3. Apply a bead of grease completely around male half
where it meets female half. Slide drive halves over
each other several times to distribute grease.
4. Apply one pump of grease to each driveline u-joint
grease fitting.
5. Apply one pump of grease to each of the plastic
driveline shield bearings.
