MASSEY 135 FOR REBUILD


MASSEY FERGUSON 135 DIESEL FOR REBUILD


HISTORY


This tractor was running perfectly, then some fine day the man from the moon came and removed the tin can that lived on top of the exhaust pipe.
Down the never ending Victorian rains came and filled up the top end of the engine with water. With a huff and a puff the engine turned over but would not start. With the aircleaner off there sounds like a blow back that could mean that one of the valves is no longer committed to it’s job…..



Rear tires are good, no cracks or deep cuts.
One front tire is new, the other has worked and starting to perish..
The bodywork is all there, no dents or parts missing.
Has a foot control accelerator.
Mudguards are both straight.
Radiator has no leaks.
Injector pump worked very well the last time the old girl ticked over.
Three point hitch also works well.
Remote hydraulic system fitted, ideal for posthole rammer.
12 Volt battery system.
Included are three front counter weights
One carry all that is sturdy but needs a new base, wood or steel.

That is that.

 

Please find below a fellow Ebay site that sells tractor spares, this is to help you along with your next tractor project.

Also find below all the technical information you need to strip and rebuild the engine.

In one sentence:

This tractor was a great runner but has had rain water down the exhaust pipe which has made her impossible to start even though she still turns over, making her ideal for a rebuild or parts…

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.
