Ferguson TE-A20 TE-C20 TE-D20 TE-E20 TE-F20 TE-H20 Service Manual, 1947–1956

Ferguson service manual for 1947–1956 TE20-series tractors, covering TE-A20, TE-C20, TE-D20, TE-E20, TE-F20, TE-H20, and TE-J20 agricultural models, plus the industrial configurations detailed in Section T. The documentation distinguishes gasoline, vaporizing-oil, lamp-oil, and diesel applications.

• Engine repair: Cylinder-head reconditioning, valve-seat work, piston and cylinder-liner service, connecting-rod inspection, crankshaft removal, and main-bearing assembly.

• Fuel systems and governors: Zenith and Holley carburetor servicing, CAV injection-pump spill timing, injector testing, fuel-system fault tables, and mechanical and pneumatic governor adjustments.

• Clutch and transmission: Clutch dismantling, release-lever adjustment, gearbox disassembly and reassembly, selector inspection, bearing setup, and power take-off shaft service.

• Hydraulic lift and linkage: Pump overhaul, control-valve servicing, lift-cylinder removal, linkage adjustments, safety-valve revisions, and fault tables for lifting and lowering problems.

• Axles, steering, and brakes: Differential and rear-hub service, steering-gear overhaul, front-axle bush replacement, agricultural brake reconditioning, and industrial dual-brake servicing.

• Electrical and lighting systems: Starter, dynamo, distributor, and control-box service information, with tractor wiring diagrams, cable-color keys, and lighting installation drawings.

Suited to mechanics and experienced owners equipped for precision measurement and major component disassembly; the engine procedures assume access to dedicated service tools and a dismantling stand.

Engine Overhaul and Cooling-System Service

You get a detailed breakdown of lubrication systems, cooling circulation, and major component overhauls, including the cylinder head, pistons, connecting rods, and timing mechanisms. The Standard Motor Co. engine tables identify gasoline engine assembly 57963 and vaporizing-oil engine assembly 500038.

Dimensional charts cover crankshaft bearing housings, camshaft end float, component clearances, and permissible wear. Engine sectional views, the Oil Distribution Diagram, and valve-seat insert charts support the inspection work. Procedures extend to reaming piston-pin bushes, recutting valve seats, and replacing diesel precombustion-chamber lower halves with the specified machining equipment.

The diesel instructions explain how mismatched liners and upper inserts leave the insert at the wrong height, and warn that unsupported piston-pin removal can break a liner flange. The cylinder-head section also cautions against cleaning precombustion chambers with the injectors installed.

Cooling coverage includes thermostat testing, radiator removal, water-pump dismantling, and changes to impeller attachment. An exploded cooling-system view identifies the related components. Use appropriate lifting equipment when handling engine blocks and other heavy assemblies.

Carburetors, Diesel Injection, and Governor Settings

The fuel chapters distinguish Zenith 24T-2 and Holley 859-A carburetors, with adjustment information, sectional drawings, and fault tables. Separate vaporizing-oil and lamp-oil material addresses their fuel arrangements and carburetor identification.

Diesel coverage includes gravity-fed and pressure-fed fuel systems, filtration, feed-pump testing, injector overhaul and testing, and injection-pump removal and replacement. Spill-timing instructions account for the relationship between the pump drive and camshaft-chainwheel adjustment. Mechanical governor linkage and the diesel pneumatic governor receive separate service instructions.

Transmission, Axles, and Brake Configurations

Gearbox procedures cover shafts, bearings, selectors, and reassembly, with a fault table addressing jumping out of gear, sticking, noise, and oil leakage. Clutch service includes driven-plate work, release-bearing replacement, and release-lever adjustment.

Rear-axle material explains differential and pinion work, bearing setup, and compatibility changes in the revised axle assembly. Steering and front-axle chapters cover sector adjustment, spindle bushes, hubs, and toe-in. Brake instructions distinguish kidney-cam and floating-cam agricultural systems.

Hydraulic Pump Diagnosis and Lift-Linkage Repairs

Hydraulic fault tables help distinguish control-valve sticking, pump aeration, cylinder leakage, and safety-valve faults when an implement will not lift or moves unevenly. This supports fault isolation before a pump or lift assembly is dismantled.

The pump illustrations distinguish oscillating control-valve arrangements and later drive-strip revisions. Service information also follows changes to valve chambers, lift covers, ram-cylinder attachments, and poppet- versus ball-type safety valves.

Lucas Electrical Systems and Industrial Equipment

Electrical service information covers starting and charging equipment, distributor adjustment, ignition components, and control-box testing. The TE-F20 diesel wiring diagram and lighting diagrams identify circuits and cable colors. The manual directs electrical repairs beyond the scope of its service notes to Lucas service facilities.

Section T explains narrow-width axle and linkage differences, including the additional rear-axle tool spacer FT.26S-17. Industrial coverage adds Girling hydraulic and mechanical dual brakes, master-cylinder service, bleeding, and Council Type lighting arrangements. Implement-compatibility notes identify equipment requiring modifications or unsuitable for narrow-width tractors.

A Sample of Valve and Distributor Settings

These examples show a small selection of the adjustment data included in the engine specifications.

For the TE-A20 gasoline engine specified on PDF pp. 21–25, cold valve-tip clearances are 0.010 in. for the intake and 0.012 in. for the exhaust.

The same specification section gives a distributor contact-breaker gap of 0.014–0.016 in., alongside ignition-setting and spark-plug data.

Chapter Bookmarks, Wiring Detail, and PDF Contents

Navigation and diagram detail: PDF text search is not available. Twenty embedded bookmarks provide access to the main sections. Small labels in the main tractor wiring diagrams benefit from zooming; some labels in the industrial lighting diagram remain indistinct when enlarged.

One printable, 408-page PDF in English. The total includes the original cover, 13 section-divider pages, and the 16-page Section U service-equipment appendix on PDF pp. 393–408.
