HYDRAULIC OIL & FILTER CHANGE
One of the most critical systems on the POSI-
TRACK is the hydrostatic drive. The hydraulic
oil should be changed every 500 hours and the
hydraulic filters should be changed every 250
hours. These precision components require ex-
tremely clean oil in order to have a long service
life. Changing the hydraulic oil and filters at the
proper intervals can prevent expensive repairs
later down the road.
Before beginning the procedure extreme care
should be taken to ensure the vehicle is in a clean
working environment. Precautions should be
taken to prevent any debris from entering the hy-
drostatic system.
1. Remove hydraulic oil drain plug (A) from bot-
tom of reservoir. Drain into suitable container.
2. The three hydraulic filters are housed on a
manifold under the engine hood. (Fig. 45)
3. The three inch and the five inch filters are both
disposable spin on type filters. These filters can
be removed by hand or by using a filter wrench.
Always dispose of filters properly.
4. The third filter is a canister type. The canister
has an interior filter element which must be re-
placed. DO NOT REPLACE THE CANISTER
ITSELF.
