1.Testing drive pressure.

∙Remove the test port plug using a 3/16” allen wrench.

∙Connect 10,000 psi gauge into the test port using a 3/8 - 24 adapter.

∙Chain machine and lock brakes.

∙Operate engine at 3200 RPM.

∙2WD, drive pressure should read 4000-4500 psi. (DO NOT exceed 5000 psi)

∙4WD, drive pressure should read 5200 psi.

Low drive pressure. (Charge pressure “OK”)

2.Possible causes.

∙Leaking check valves.

∙Leaking acceleration valves.

∙Leaking bypass valve. (tow valve)

∙Worn drive pump.

∙Worn drive motor.

3.Performance results.

∙Noisy operation. (Oil leaking past check valves or acceleration valves)

∙Poor hill climbing performance. (Slows or stops on hills)

∙Complete drive failure.(Unit stops moving)

Relief Valve

The 4 wheel drive unit has an externally mounted relief valve. To check the relief valve setting, the test gauge must be connected to the forward test port on the bottom of the hydrostatic pump.

Than test the pressure as usual.

The relief valve is set to limit the drive pressure to 5200 PSI.
