This Page has absolutely nothing to do with boats and waterways.
I am simply using the web site as a convenient way for a friend to follow the overhaul of his tractor - useful as a few problems are discovered.

Ferguson. Type TE-A20
Manufactured 1948
No A69802
Built by Standard Motors. Engine - Standard 80mm Petrol. (Same engine as the Standard Vanguard)

Top of engine block. Showing path of coolant water leaked under head joint into push rod space.

Front axle trunnion pin heavily worn. Housing cleaned up and primer coat applied. Holes in housing are slightly worn, may need to be built up with weld. Bush in axle beam to be renewed.

Oil filter. Engine oil had been recently changed, possibly to disguise water contamination, but filter had not been renewed. Photo shows dirt and grit.

No 4 push rod to the left is same as 6 other rods, but No 5 to the right is different type, note large bottom end. This is of no importance since the guide sleeve is also one off, of correct type for the odd rod.

Heavy leakage of engine oil past crankshaft rear seal into clutch space. Seal must be changed but I am trying to ascertain if this can be done without removing crankshaft from engine - that would mean complete dismantling of engine.

Starter ring gear teeth are seriously damaged in one small segment (where engine normaly comes to rest when stopped) remaining teeth are slightly set over.

Aluminium sump cleaned up ready for painting. Previous repainting had been carried out so badly that in order to do a decent job extensive removal of old soft, badly adhering paint is necessary.

This unfortunately is serious. View of cylinder head core plug showing four fractures (cracks)

The next five photos of cylinder head after stripping down and cleaning show four fractures in way of core plug. Two of these fractures extend through the main body of the head for a distance of three and a half inches towards front and back ends of head.

When exhaust and inlet valves were removed all valve stems were found to be very slack in the guides. All very dirty, Evidence of blow past valve stems causing carbon and dirt deposits in rocker space.

Governor/Timing chain cover cleaned up ready for painting. Old crankshaft seal not yet removed.

Shows new axle centre pin fitted. Note that the new pin is of insufficient length and only seated on half the thickness of the rear end of support housing.
3mm of housing wall can be seen aft of pin end.
The only means of lubrication for this bearing is a diametrical oil hole in bottom of hollow pin which should be filled with a long spouted oil can after 480 working hours - Optimistic or What?

A poor photo of the old worn pin. The step (wear) at the extreme end shows that this also had been seated on only a 3mm thickness of the housing wall.

Replacement used cylinder head purchased from "Fergiland" Valves and seats need some cleaning up.

After cleaning up Valves were found to be in reasonable condition, acceptable fit in guides, but the valve seats are in poor condition with considerable pitting of ex v/v seats requiring considerable grinding. Actualy needed recutting but facilities not available.

I don't know how long this head had been in storage, but there was a mouses nest inside the water space.

Original 6V Dynamo on left with large heavy mounting lugs. Note large diameter spindle and drive pulley for original thick heavy duty fan belt.
On right replacement 12V dynamo with smaller dia spindle.

New adaptor bracket to permit fitting of modern 12V dynamo. Cost of bracket £34. The new dynamo was only £50.

So far primer has been applied to bare areas by brush, also brush painted small parts removed in course of overhaul. Will now mask and spray paint normaly inaccessible areas.
