Splitting a tractor to get at the clutch or rear axle is not a job you want to do twice, and this Ford 1000, 1600 service manual PDF (OEM ID 40100020, 116 pages) walks you through that teardown along with engine, fuel, electrical, hydraulic, steering, and wheel service on both diesels. Factory wiring diagrams trace the charging and starting circuits, while hydraulic schematics map oil flow from the pump through the control valve. When a cold engine won't fire or the differential lock drags, troubleshooting tables point you toward the likely cause before you loosen a bolt. Set alternator output between 13.5 and 14.0 volts, and torque the flywheel nut to 100-120 kg-m (723-868 lbs. ft.), figures printed on Ford's own spec pages. Guessing costs you a bearing and a second teardown. The bookmarked, keyword-searchable file travels with you, so the specs are wherever the tractor quits.

Ford 1000, 1600 Common Problems This Manual Covers
Brake pedal goes nearly to the floor and tractor pulls to one side when braking
Measure brake pedal free play before tearing into the drums; spec is 20 to 30 mm, and anything past 30 mm needs adjustment. Equalize both pedals so the tractor stops straight, then pull the drums and measure inside diameter: 170 mm (6.70 in.) is the wear limit. Replace glazed or oil-soaked linings while you are in there.
Manual Section: Brake Troubleshooting p. 89PTO shaft slips under load and rear PTO grinds when engaging the mower
Verify engine speed first: 540 rpm PTO output needs 1955 rpm at the engine, so a lazy governor reads like PTO slip. Inspect the 3.49 cm (1.35 in.) 6-spline shaft, listed on page 90, for twisted or rounded splines, and measure counter shaft to slide gear spline clearance; replace parts worn past the .25 mm allowable limit.
Manual Section: Transmission, Differential, Rear Axle, and Related Parts p. 90Battery goes dead overnight and the ammeter shows no charge with the engine running
Test charging voltage at the battery with the engine running; spec is 13.5 to 14.0 volts, listed on page 49. If low, verify the field relay points close at 3 to 4 volts as shown on page 47, then set the regulator gaps to the values on page 65. Slow charge a dead battery at 3 to 4 amperes before retesting.
Manual Section: Alternator Charging System p. 49Frequently Asked Questions
What is the torque specification for the cylinder head nuts on the Ford 1000 and 1600 tractors?
The cylinder head nuts must be tightened in the proper sequence to a torque of 15.0-15.5 kg-m (108-112 lbs. ft.). p. 32
How do you fix ford 1600 diesel idles down, dies in the field, then cranks but will not restart?
Check fuel flow at the filter bowl first; a clogged element starves the injection pump at low idle. Replace the filter and bleed air from the lines following the fuel system section starting on page 33. Verify injection timing is at 21 degrees BTDC, the spec on page 30, before condemning the pump. p. 33
How do you fix battery goes dead overnight and ammeter shows no charge with engine running?
Test charging voltage at the battery with the engine running; spec is 13.5 to 14.0 volts, listed on page 49. If low, verify the field relay points close at 3 to 4 volts as shown on page 47, then set the regulator gaps to the values on page 65. Slow charge a dead battery at 3 to 4 amperes before retesting. p. 49
How do you fix loader bucket cylinder and joystick spools leaking hydraulic oil, bucket drifts down under load?
Check hydraulic oil level before pulling anything apart; low oil aerates the pump and mimics bad seals. Replace the bucket cylinder packing and spool O-rings, then refill the system to its 10 liter capacity, the figure on page 100. Trace circuit routing with the hydraulic schematic on page 93 to find pressure loss points. p. 100
