NO GEAR MOVEMENT
If all three motors release at this point, the motor pack appears to function properly. Remove the hydraulic pack from the hydraulic modulator. Refer to "Motor Pack". Rotate each gear on the hydraulic modulator by hand. The front gears should be free to rotate approximately 8.5 turns lock to lock. If the gears do not turn freely or if at least eight turns are not possible, replace the hydraulic modulator. Refer to "Hydraulic Modulator/Motor Pack Assembly".
The rear gear should rotate approximately four turns. If the gear does not turn freely or if at least 3.5 turns are not possible, replace the hydraulic modulator.Hydraulic Modulator/Motor Pack Assembly
