Daily check

Safety first

Never use your hand to search for a hydraulic or injection leak.

Use cardboard or paper. Fluid injected into skin needs immediate medical attention. Manual pp. 33 and 44.

Maintenance schedule

Intervals are operator-manual intervals. Work sooner after severe dust, heavy load, water exposure, or long storage.

Common jobs

Check engine oil level
  1. Park level and stop the engine long enough for oil to settle.
  2. Check the dipstick. Keep the level between the ADD and FULL marks.
  3. Add oil through the engine filler cap only as needed. Do not overfill.

Manual p. 35.

Change engine oil and filter
  1. Warm the engine, park level, lower implements, stop the engine, and chock safely.
  2. Drain both engine-oil drain plugs into a suitable container.
  3. Replace the filter when due. Lightly oil the new gasket and install per the filter maker's directions.
  4. Refill, run briefly, stop, wait for oil to settle, then verify with the dipstick and inspect for leaks.

Oil: every 100 hours. Filter: every 200 hours. Manual p. 55 prints two crankcase capacities: 7.9 U.S. qt / 7.5 L without a filter change, and 8.5 U.S. qt / 8.0 L with a filter change. Treat the capacity as a refill reference: finish by checking the dipstick and do not overfill. Manual pp. 35-36 and 55.

Check transmission, rear axle, and hydraulics
  1. Park level and wait for the oil to settle.
  2. Check the transmission dipstick. The correct level is between the marks.
  3. If low, add the specified fluid through the filler plug. Do not fill beyond the mark.

Change shared transmission/rear-axle/hydraulic oil every 300 hours. Capacity: 34.9 U.S. qt / 33.0 L. Manual pp. 38-39 and 55.

Service air cleaner
  1. Inspect daily or every 10 hours and clean every 100 hours.
  2. Do not remove the element while the engine is running.
  3. Replace the element seasonally, or sooner if damaged or no longer serviceable.

Manual maintenance chart and pp. 46-47.

Drain fuel-filter water and sediment
  1. Drain the fuel filter every 50 hours and whenever contamination is suspected.
  2. Clean the filter every 100 hours and change its element every 200 hours.
  3. Keep dirt and water out of diesel storage and transfer containers.

Manual chart and pp. 32-33, 42-43.

Check coolant and radiator
  1. Check coolant daily or every 10 hours only when the engine is cool.
  2. Keep radiator fins clear of chaff and debris.
  3. Change coolant seasonally; inspect hoses and clamps at the same time.

Total cooling-system capacity: 8.5 U.S. qt / 8.0 L. This is the system's total coolant-mixture capacity, not a direction to pour in 8.5 qt of antifreeze concentrate. Manual pp. 30-31 and 55.

Check fan / water-pump belt
  1. Inspect at 200-hour intervals and adjust if needed.
  2. Apply 20-25 lb (9-11 kg) midway between pulleys.
  3. Target deflection is 7/16 to 9/16 in (10-15 mm).

Manual p. 56.

Grease chassis points

Every 50 hours, grease steering linkage, pivot shaft, clutch pedal, brake pedal, pedal shaft, 3-point linkage, and power-steering-cylinder fittings. On 2WD tractors also grease the front wheel spindles. Manual pp. 30-31.

Exact printed capacities

Engine oil with a filter change and total cooling-system capacity are both printed as 8.5 U.S. qt / 8.0 L. They are separate fluids with coincidentally matching capacities. For any refill, use the tractor's dipstick or level mark as the final check and do not overfill.

SystemU.S.ImperialLiters
Fuel tank11.1 gal9.2 gal42.0 L
Cooling system: total coolant mixture8.5 qt7.0 qt8.0 L
Engine crankcase: less filter7.9 qt6.6 qt7.5 L

Rear axle and transmission: includes hydraulics34.9 qt29.0 qt33.0 L
Power steering1.9 qt1.6 qt1.8 L
Front axle differential case and final reduction4.2 qt3.5 qt4.4 L

The values above are transcribed as printed, including the manual's front-axle figures. Cooling-system capacity means the complete coolant mixture, not antifreeze concentrate alone.

Which lubricant goes where

SystemManual-printed lubricant
Transmission, rear axle, final reduction, hydraulic system, power steeringFORD 134
Engine crankcaseFord Tractor Super Premium Engine Oil or API SF/CD quality oil. Select the SAE grade for outside temperature using the manual's chart.
Front wheel bearings and lubrication fittingsM-1C-137-B or NLGI grade 2 EP grease with lithium soap

These are the original manual terms. When buying a current product, confirm the modern equivalent with New Holland or a qualified supplier before filling.

What changed since the manual

The manual discusses adjusting oil intervals for high-sulfur diesel. EPA says U.S. nonroad diesel is now ULSD, capped at 15 ppm sulfur after the phase-in completed in 2014. The manual's normal oil interval is therefore the useful baseline for ordinary U.S. fuel, while severe operating conditions can still justify earlier service.
