Assembling Cylinder Head

When replacing the rocker assembly ensure the slot at rear end of rocker shaft is in line with the punch mark on the rear pedestal bracket. The relationship of this slot to the punch mark determines the quantity of oil delivered to the rockers and bearings.

Adjust inlet and exhaust clearances to 0.012″.

Adjusting Valve Clearances

Remove the rubber plug in the inspection hole in the left front side of the transmission housing adapter plate.

Rotate crankshaft until the T.D.C. line on the flywheel is in the centre of the inspection hole and No. 1 piston is on the compression stroke (both vavles fully closed).

Check and adjust clearances on Nos. 1,2, 3 and 5 vavles.

Turn crankshaft one revolution and repeat for Nos. 4 and 6 vavles
(T.D.C. mark visible through inspection hole).

Replace rubber plug in adapter plate.

Vavle clearances for both inlet and exhaust should be set to 0.010″ hot, and 0.012″ cold.

Oil Pump

Check clearance using a feeler gauge between maximum diamater of inner rotor and minimum diameter of outer rotor, clearance should not exceed 0.006″ (or replace/refurbish pump).

Clearance between driven rotor and pump body not to exceed 0.010″.

Placing a straight edge over top of rotor faces, measure clearance between top of rotors and surface of pump body – not to exceed 0.003″.

Piston Rings

Compression and oil control ring gaps should be within 0.009″ – 0.013″ (measured in a ring gauge of 3.6″).

Cylinder Liners

When the liners are fully in position, the top face of the liner flange shoule be 0.001″ – 0.009″ below the top face of the block.

Tolerances

Standard Crankshaft Main Journal Diameter, 2.7485″-2.7490″.
Big End Crankpin Diameter, 2.2485″-2.2490″
Small End Bush (internal diameter), 1.2505″-1.2515″

These figures are taken from the Massey Ferguson 35 Service Manual. Whilst every effort has been taken to reproduce these figures accurately, no responsibility can be taken for errors.

The first tractor to come off the production line was the TE20 on 6th July 1946. Originally this was fitted with an American engine called the Continental Z-120, but in September 1948 a 2088cc Standard engine became available. Production continued until 1956, after a total of 517,651 grey fergies (serial numbers) had rolled off the line.

Ferguson badged the original model as the TE-20, but went on to produce a range of variants…..

TE-20 Continental Z-120 petrol engine, 1946-1948
TEA-20 Standard Motor Company petrol engine, 1947-1956
TEB-20 Continental Z-120 petrol engine – Narrow, 1946-1948
TEC-20 Standard petrol – Narrow, 1948-1956
TED-20 TVO Standard engine, 1949-1956
TEE-20 TVO Standard engine – Narrow, 1949-1956
TEF-20 Standard diesel, 1951-1956
TEH-20 lamp oil Standard engine, 1950-1956
TEJ-20 lamp oil Standard engine – Narrow, 1950-1956
TEK-20 petrol Standard Engine – Vineyard, 1952-1956
TEL-20 TVO Standard engine – Vineyard, 1952-1956
TEM-20 lamp oil Standard engine – Vineyard, 1952-1956
TEP-20 petrol Standard engine – Industrial, 1952-1956
TER-20 TVO Standard engine – Industrial, 1952-1956
TES-20 lamp oil Standard engine – Industrial, 1952-1956
TET-20 Standard diesel engine – Industrial, 1952-1956
TO-20 Detroit built Continental Z-120 engine, 1948-1951
TO-30 Detroit built Continental Z-129 engine, 1951-1954

Over 25,000 TE20’s were exported to the USA to fill the gap left in the market when the last Ford Ferguson came off the production line in Detroit in June 1947, but before the Detroit assembled TO20 came into production in 1948.

Vintage tractor engineer,
Sir, would you know where I could get hold of a complete illustration of the breakdown of the motor of a TEA 20 Fergie.
I pulled the motor down 12 months ago and have begun to re-assemble same.
I want a breakdown of the motor just to make sure I re-assemble the motor correctly.

The only thing I could suggest is a manual. Try Classic Tractors

http://www.classictractors.co.uk/shop/asp/prodtype.asp?PT_ID=158&strPageHistory=cat

who do both workshop manuals and parts books for the TE 20’s.
