Ford TW-5 to TW-35 Series Common Problems This Manual Covers
Ford TW Series clutch pedal engages like an on/off switch, transmission shifts harsh between gears
Check clutch pedal free travel first: measure it at the pedal, per page 78 it should read 1-1/8 to 1-5/8 inches before resistance. Adjust the release shaft linkage if it's out of spec. If the clutch still grabs like a switch, pull the cover and inspect the friction discs and pressure plate for wear or oil contamination from a leaking seal.
Manual Section: Clutch p. 78Steering wheel feels heavy and responds slowly to input, especially at low engine RPM
Check the troubleshooting steps on page 32 for hard or slow steering response. Verify the power steering relief valve opening pressure reads 1550-1650 psi. If pressure is low, inspect the steering pump for wear or a clogged filter, and check fluid level and condition before condemning the pump.
Manual Section: Hydrostatic Power Steering p. 32Battery keeps dying overnight and dash gauges flicker while engine is running
Test the alternator and regulator circuits on pages 66 through 68 in order: battery voltage, excitation voltage, field circuit, then alternator output. Verify battery voltage at rest reads above 12.4 volts. If excitation voltage is missing at the regulator terminal, check the wiring harness and brushes before replacing the alternator.
Manual Section: Electrical System p. 66PTO clutch keeps slipping under load or won't fully disengage when lever is pulled
Check PTO system pressure on page 120; at 2200 rpm it should read 185-235 psi. Low pressure under load points to a worn PTO clutch pack or a leaking control valve. Inspect the pressure regulating valve and clutch piston seals for wear, and verify the control linkage is adjusted correctly before tearing into the clutch pack itself.
Manual Section: Power Take-Off p. 120Three-point hitch lifts too slowly or won't raise implements even under light load
Check system relief valve pressure on page 129 for tractors built before April 1985; it should read 2450-2550 psi (16895-17580 kPa). Low pressure points to pump wear or a stuck relief valve. Verify hydraulic fluid level and filter condition first, then run the pump flow rate test before pulling the pump for overhaul.
