Hydraulic Oil Cooler Replacement

Hydraulic Oil Cooler Removal

Machines built prior to 2008:

Under certain conditions

higher than desired case drain pressure or hydraulic
pressure “spikes” can force oil past the tandem pump
trunnion shaft seal. To correct this, there is an oil cooler
kit (115-3565). With trunnion shaft seals, a larger cap-
acity oil cooler and increased diameter (from 3/8” to 1/2”)
case drain hoses and fi ttings. Refer to Z Master Zero
Radius Tractors Service Bulletin #93 Issued: March 7,
2008.

1. Park the machine on a level surface, disengage the

PTO, engage the parking brake, turn the ignition off
and remove the key.

2. Raise the seat.

3. Remove the negative battery cable from the battery.

4. Raise the hood assembly.

5. Remove the 3 bolts, washers and nuts securing right

side top frame brace. Remove the top brace (Fig.
366).

9. Install the negative battery cable from the battery.

10. Lower the seat.

8. Install the front engine panel (Fig. 365).
