S-8 HYDROSTATIC TRANSMISSION — LOSS OF
OUTPUT TORQUE
Loss of output torque is caused by one of the fol­
lowing reasons.
1. Heat. The operating temperature of the
transmission fluid has exceeded 180° F.
A. Coolingfan on backwards. Cupped side of fin
to be toward transmission. See Figure 1.
B. Dirt and grass in cooling fins. Do not clean
transmission with pressure water or steam
(unless a shield or cover is placed over the
reservoir cover during wash operation, or in
other situations where water may be intro­
duced into the system). This will cause
moisture in the system. Refer to paragraph 2.
C. Low oil level. Oil level in expansion reservoir
must be
'/2
full. Use type "A" transmission
fluid.
D. Air lock. Air can be locked inside the trans­
mission causirig a low oil level situation. To
bleed air out, remove the free wheeling valve
on top of transmission pour type "A" trans­
mission fluid into expansion reservoir until
fluid runs out free wheeling valve hole. Re­
place free wheeling valve. Start unit and
operate transmission for approximately 2
minutes to attempt to free any air that may
still be locked ipside. Stop unit and allow to
set for at least 5 minutes. Remove free wheel­
ing valve to allow the remainder of the air to
escape and replace. Fill expansion reservoir
to
'/2
full with type "A" transmission fluid.
2. Water in transmission fluid. Milky appear­
ance. Remove the expansion reservoir and the trans­
mission from the tractor. Remove hex plug, adaptor
filter, and free wheeling valve. NOTE; Adaptor filter
has left hand threads. Flush complete system with a
fast drying solvent. Reassemble the transmission and
all related parts in the tractor. Fill the transmission
with type "A" transmission fluid eliminating air lock
as described in paragraph 1-D above.
3. Free wheeling valve. Valve should be fully
extended. Length beyond nut is approximately %
inch.
4. Internal leakage due to wear. This condition is
unusual; however, when it occurs, replace the
transmission.
S-8 HYDROSTATIC TRANSMISSION — SERVICE PARTS
1. We have made available the input shaft and
related parts, and also the control shaft seal in
addition to other items previously available. SEE
ILLUSTRATION BELOW.
BATTERY SERVICE
Check the battery electrolyte level once each
week or every 25 hours of operation. Check it monthly
if the tractor is idle or is in storage. Add distilled
water to bring the level to the bottom of the split ring
in the filler tube of each cell.
Each spring and fall clean the battery and ter­
minals with ammonia or bicarbonate of soda solution
