Warm the hydraulic oil to 120°F (50°C) by operating the system as instructed on page 760. Set the engine speed to 1650 rpm according to page 762 and test the pump output pressure. Drain the fluid and replace the filter if the pressure drops under load.
Manual Section: Hydraulic System Troubleshooting p. 760Manual transmission slips under heavy load requiring frequent adjustment or makes grinding noises when engaging gears.
Inspect the clutch assembly for worn plates or a damaged release bearing. Replace worn components and torque the single clutch cover to flywheel bolts to 23-29 Lb. Ft. as specified on page 254. Check the linkage alignment if slipping continues after reassembly.
Manual Section: Clutches p. 254Engine oil pressure warning light stays illuminated or flickers intermittently during normal operating conditions.
Test the oil pressure switch operating pressure to ensure it triggers between 8-12 psi. Review the specifications on page 208 to verify the switch calibration. Replace the sending unit if it activates outside this range and inspect the wiring harness for shorts.
