CHARGE PUMP LOCATION
e) To "prime" charge pump, loosen two hex socket head capscrews (shown in
Figure 11) 1-1/2 turns only. Make sure engine is not running. Lift
charge pump housing upward and wait for a steady flow of oil to flow out
from under housing. Retighten capscrews. Do this for both pumps.
Note: Hydraulic reservoir can be pressurized to up to 5 psi (35 kPa) to
speed this process.
f) If either drive wheel still does not rotate, stop and repeat Steps (d) through
(e) above for the respective pump. If tires rotate slowly, the system may
prime after additional running. Check oil level as stated in Section 5.1.8.
g) Allow unit to run several minutes after the charge pumps are "primed" with
drive system in the full speed position.
Check oil level as stated in Section 5.1.8.
h) Check hydro drive linkage adjustment as stated in Section 5.2.6.
Check tire pressures.

b) Inflate tires to pressures stated above. Measure the circumference of each
drive tire. Adjust tire pressures within the above range to try to make tire
circumferences match as closely as possible.
