Maintenance

4. Thoroughly clean the area around each of the charge pump housings.

5. To “prime” charge pump, loosen two hex socket

head capscrews (shown in Figure 14) 1 1/2 turns

only. Make sure engine is not running. Lift the charge pump housing upward and wait for a steady flow of oil to flow out from under the housing. Retighten the capscrews. Do this for both pumps.

Note: Hydraulic reservoir can be pressurized up to 5 psi to speed this process.

6. If either drive wheel still does not rotate, stop

and repeat steps 4 and 5 above for the respective

pump. If wheels rotate slowly, the system may prime after additional running. Check oil level as stated in Check the Hydraulic Oil Level section.

7. 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 Check

the Hydraulic Oil Level section.

8. Check hydro drive linkage adjustment as stated in

Hydro Drive Linkage Adjustment section in

Adjustments.
