Mccormick W4 Tractor, McCormick W4 Tractor Common Problems This Manual Covers
McCormick W4 Tractor clutch release bearing is noisy or rough during operation and gear shifting p. 64
Check the clutch pedal linkage for proper adjustment. Verify a clearance of 3/16 inch is maintained between the clutch release bearing and the levers as shown on page 64. Adjust the pedal rod length if the measurement is incorrect to prevent continuous bearing wear.
Manual Section: ClutchHydraulic remote control system fails to respond or lifts implements very slowly under heavy load p. 69
Drain the hydraulic system completely and clean the suction screen. Fill the reservoir with approximately 8 quarts of fresh hydraulic fluid as directed in the troubleshooting procedures on page 69. Test the remote cylinder operation under a load to confirm proper pressure recovery.
Manual Section: Special EquipmentStarter motor jams completely and fails to engage the flywheel ring gear when pressing the button
Inspect the starter motor mounting bolts for tightness. Check the wiring diagram for correct battery connections. Ensure the clutch pedal is fully depressed to maintain the required 3/16 inch release bearing clearance before attempting to crank the engine again.
Manual Section: Ignition and Electrical ProblemsEngine turns over but fires a few times and dies despite cleaning the tank and sediment bowl
Inspect the fuel shut-off valve and ensure it is fully open. Check the clutch pedal to verify the 3/16 inch clearance is maintained to reduce starter drag. Clean the main fuel lines and drain the carburetor bowl to remove any remaining trapped moisture or debris.
Manual Section: Hard to StartFrequently Asked Questions
How to reset 1948 McCormick Deering W4 tractor distributor?
To time the distributor for battery ignition, set the engine to No. 1 T.D.C. firing stroke, then advance the distributor by turning the body about 30 degrees in the cam rotation direction until a spark occurs when the secondary cable is held 1/16" to 1/8" from the primary terminal. For magneto, crank the engine to No. 1 piston upper dead center compression stroke, turn the magneto coupling counterclockwise until the metal strip on the rotor points to the No. 1 terminal on the cap, then install and recheck timing by observing the impulse coupling trip. Refer to pages 41 and 44 for complete instructions.
How to reset fuel system on McCormick Deering W4 tractor?
To adjust the carburetor, first close both fuel adjusting screws, then set the main fuel adjusting screw 2-1/2 to 3 turns open and the idle fuel adjusting screw 1 to 1-1/2 turns open. After the engine is hot, fine-tune the main fuel adjusting screw until the engine operates steadily under load, keeping the adjustment as lean as possible. Refer to page 36 for detailed instructions.
