1970s–1980s Massey-Ferguson 1010 / 1020 Tractor Service Manual

This shop manual covers the 1970s–1980s Massey-Ferguson 1010 and 1020 tractors, including Standard and Hydro models in 2WD and 4WD configurations. It covers repair, inspection and adjustment of the Hinomoto engines, drivetrain, steering and hydraulic lift system.

Engine Overhaul, Transmission Tests and Tractor Systems

These selected topics outline the repair coverage rather than reproduce the full index. Other subjects include radiator removal and water-pump service.

• Engine repair: Engine removal, cylinder-head service, camshaft and piston installation, crankshaft inspection and oil-pump service, with related clearances and tightening specifications.

• Diesel fuel system: Fuel-system bleeding, injection timing with shims, governor adjustment, injector testing and glow-plug checks.

• Transmission diagnosis: Standard gearbox overhaul, Hydro troubleshooting, charge and relief-pressure tests, pump-vacuum checks and ground-speed control adjustment.

• Clutch and PTO: Clutch splitting, friction-disc inspection and installation, model-specific rear PTO service, Hydro mid-PTO overhaul and electric front-PTO checks.

• Axles and brakes: Front-drive axle overhaul, differential and bevel-gear adjustment, rear final-drive service, differential-lock linkage and mechanical brake repair.

• Steering and hydraulic lift: Manual steering-gear overhaul, power-assist cylinder seal replacement and bleeding, hydraulic-pump overhaul, relief-valve tests and lift-control adjustment.

• Electrical diagnosis: Hitachi starter inspection, alternator and regulator checks, safety-start switch testing and model-specific wiring diagrams.

Suited to experienced mechanics equipped for tractor splitting, precision measurement and hydraulic pressure testing.

Engine Inspection and Diesel-Service Limits

The cylinder-head section addresses swirl-chamber inserts and advises against resurfacing the head. Piston and connecting-rod illustrations distinguish the installation orientation used on each model, while the bearing sections provide standard dimensions, repair sizes and wear limits.

Injection timing is explained through crankshaft timing marks and pump-mounting shims. Injector testing covers opening pressure, spray pattern and leakage. The sealed “Ungleich unit” is identified as a torque limiter whose adjustment requires test equipment.

The diesel section limits pump and injector service to removal, installation and exchange unless the required tools, specifications and training are available. It also warns that attempting to start the engine before bleeding air from the fuel system can damage the injection pump.

Hydrostatic Tests and Driveline Setup

Hydro troubleshooting addresses failure to move, reduced power, abnormal noise, neutral creep and overheating. The pressure and vacuum tests help distinguish supply restrictions, relief-valve faults and internal leakage before the unit is removed.

The manual provides step-by-step procedures for hydrostatic-unit removal, disassembly and reassembly. An important model difference is the adjustable high-pressure relief valve on the 1010 Hydro; the 1020 Hydro uses nonadjustable cartridge valves.

The Standard transmission sections distinguish main and range gearing from the 1020’s creeper transmission. Exploded views support component identification and reassembly, while shim-selection instructions distinguish bearing retention, pinion position and backlash adjustment. Bevel-gear contact-pattern illustrations support the final mesh checks.

On the 4WD front axle, loose kingpin bearing balls can cause extensive damage if trapped between gear teeth or omitted during assembly.

Steering, Lift Controls and Electrical Circuits

A manual steering-gear cross section and an exploded power-assist cylinder view accompany the steering procedures. Hydraulic lift coverage extends through control-valve overhaul and linkage adjustment, including use of the MF 7548 clearance gauge.

Separate oil-flow schematics show the 1010 Hydro and 1020 Hydro circuits. Wiring diagrams distinguish the models and explain the single clutch-operated starting switch on Standard tractors versus the range and PTO safety switches on Hydro tractors. Hitachi S114 starter test data supplement the charging-system and glow-plug checks.

Due to the high pressures and heavy components involved in these procedures, always adhere to standard workshop safety protocols when handling hydraulic lines or supporting the chassis.

A Preview of Engine Clearances and Pressure-Test Data

Engine inspection: Cold valve clearances are 0.30 mm intake and 0.35 mm exhaust. The crankshaft section gives a main-bearing diametral clearance of 0.030–0.095 mm, with a maximum of 0.15 mm.

Oil and Hydro checks: The engine lubrication section lists oil pressure of 98 kPa at 800 rpm and 490 kPa at 2700 rpm. For the 1010 Hydro, charge pressure is 421–559 kPa with the fluid at operating temperature and the engine at 2500 rpm.
