LUBRICATION
41
IMPORTANT:
Check the dipstick reading be-
fore adding the last 1/2 pint of oil and
fill only
to
the “F” mark.
DO NOT
overfill the crankcase
(oil above “F” mark) as this
CAN
result in en-
gine overheating, loss of power, and possible
engine damage.
10. Start the engine and check for oil leaks around
the oil filter. Stop the engine, recheck the oil
level, and add oil if necessary. (When the en-
gine is first operated with a new oil filter, the oil
level drops slightly as the filter is filled with oil.)
Mower Deck Gearbox Lubrication
On gear driven decks, the mower deck gearboxes
(tee gearbox and blade drive gearboxes) are con-
nected as a unitized assembly, and oil flows freely
between them. The gearboxes are permanently lu-
bricated (oil filled) and sealed requiring no sched-
uled lubrication. However, the gearbox oil seals
should be checked
every 25 hours
for indication of
an oil leak;
particularly the lower seals
on the
blade drive gearboxes should be inspected, since
they operate in a dirty environment. If an oil leak is
noted, replace the oil seal and relubricate the gear-
box assembly as follows:
1. Remove gearbox cover (footrest). Deck orien-
tation should be the normal operating position.

2. Clean the area around the individual gearbox
cover plates to prevent contaminants from en-
tering the gearcase.
3. Remove the screws securing the cover plates
on the blade drive gearboxes.
4. Check the level of lubricant in the gearboxes. If
the lubricant is low, add SAE E.P. (Extreme
Pressure) 80W-90 (API GL-5) gear lube until
the oil level is up to (submerges) the horizontal
shaft in the gearbox (shaft parallel to cover
plate).
NOTE:
In case the gearboxes are completely
drained of oil, approximately 5 fl. oz. (15 cl) of oil
per gearbox is required to refill the gear drive
assembly.
NOTE:
Since the gearboxes are connected as
a unit by connector tubes, it is necessary to add
oil slowly. Allow a few minutes after adding oil
for the oil to flow throughout the assembly and
the oil level to stabilize before reassembly.
IMPORTANT:
DO NOT
overfill the deck gear-
boxes. The gearbox assembly is not vented,
and overfilling with oil will cause excessive pres-
sure and result in oil leaks.
5. Check condition of the cover gasket and replace
if worn or damaged. Reinstall gearbox cover
plates; torque screws to 24 lb
·
in. (3 N
·
m).
Grease Fitting and Oil Point Lubrication
Lubricate the grease fittings and oil points after
ev ery
25 hours
of operation. Lubricate
more often
when
operating in
dusty or dirty conditions.
Use SAE
general purpose lithium or molybdenum base grease
for grease fittings and light machine oil (SAE 10) to
lubricate oil points.
Lubricate the locations shown
in the Chassis and Deck Lubrication Points
illustration.
NOTE:
PTO universal joints (on the deck and trac-
tor) require routine lubrication
after every
25 hours
of running time. Remove tractor PTO quick discon-
nect tube assembly for easy access to grease fit-
tings.
NOTE:
The best way to lubricate the PTO tube half
of the universal joint assembly is to remove it from
the tractor. See instructions for removing and install-
ing PTO quick coupler, refer to
