Finally got the girl home....not too bad of shape... my next winter project. Thanks for help on my last post.

Dunno what you intend doing, but the weak points of the engine are the governor bearing oil feed pipe and maybe the top end oil feed to the rockers.

Although perhaps not as common as the 80 models, valves dropping into the engine are not unknown.

My Ollie 90 suffered all three of those failures in its working life. Governor housing was trashed when weights let go and the dropped valve siezed the engine (left unattended) as well as trashing the hardened seat, other valve and distorted the inlet valve seat. It cracked the head as well. All repaired 30 years ago.

You may possibly find that top gear has been locked out if it was late enough to be fitted with a four speed box (I believe) and was supplied on spade lugs.
 
Pulls like train. Always starts easily. Mine was bought by my father in 1948, so quite a late model. I knew a fellow that fitted a 3 point linkage to one (although it may have been on an 80). I like mine. Not so many around, so fairly rare. Built like a brick bog. I doubt if the original liners ever wear out. If looked after, will see out any modern day tractor, I expect. They must have been a revelation in tractor power when introduced.

Mine was well looked after in its earlier years and the governor explosion was the only real expense that I can recall. I can remember it had the valves reground once, but I don?t know why.

Since putting mine back together (around 1988) - it was in pieces for over 25 years - I?ve not run it so much, but I don?t ?spare the horses? when ploughing on very heavy land with a rusty 3 furrow deep digger Fordson plough. It is a KD version with a C66 transmission.

Yours is much straighter than mine. Lovely old machine. Enjoy.

Ok and thanks for the help. This has been in a shed for 30 yrs...where do I start to get it running? Spark? Clean tank? Pull it to start? It does turn with the crank but turns hard....lol....thanks.

I wouldn't pull start it. Go through everything tune able. Spark, fuel, and valve settings. If it's been setting a long time, put some ATF in each cylinder. Make sure you getting good spark and fuel. Time it, and try hand cranking it. I got a 41 MM ZTN that had set a long time running that way. Good luck.
 
okay...I will assume the "timing" is correct...it ran when parked. There are two levers up under the steering wheel....that I
think go to the mag- wonder what they do? Thanks.
 
Remove plugs to aid turning by hand, oil everything before trying to start, it won?t go without air, fuel and spark, so all need to be checked. Transmission is being turned with the engine - that may be causing drag. Oil onto pistons to help lube the cylinders would be good. Anything in the oil would have settled to the bottom, if a non-detergent oil was used.

Don?t start until oil pressure is confirmed. Lots of small detail to make sure you don?t damage/break anything when it is started.

After that length of time the clutch may be stuck - depending on storage conditions, but easily checked with the crank handle, in gear and clutch pedal depressed.

Tank may need cleaning, may not. A flush may be good enough. The gauze filter, if it has one, inside the tank may have rusted away. Is the sediment bowl functional?

If it has not been turned over in that time one exhaust valve will have been open and that cylinder may even have had a nest of insects in it!

There can always be issues with these old tractors. I have one 90 engine with completely broken up big end bearings, a very oval crankshaft, cracked manifold and with loose woodruff keys on timing gears and oil pump drive. A right mess, but recoverable.

After starting, do check there is oil feed to the governor and rocker shaft. Oil pressure on the guage does not mean everything is being oiled!

Remember, it only has a bypass oil fitration system - good enough, but dirty oil can circulate to the bearings if trash is lifted into suspension with a modern detergent oil.

Ok...thanks for the advice; do you have a pic to post of your "90" ? I would like to see one; also...what are the two levers below the steering column- next to the tank? Governor controls? Thanks.
 
Don?t know on a 28-44. Likely governor and magneto advance, I would think. I don?t think the base mount mags had an impulse coupling on the mag, so needed to be retarded for starting. Can?t recall the 90 kicking back (l do remember the Fordson Standard was a problem, mind - and also the Wisconsin VE4, which had a very short starting handle).

My last pics are long gone on an old ?puter, but there are pics on ?goggle? images of model 90 tractors. Much the same as a 28-44 but with side louvres and panels, so you can?t see much. Beware that some on ?goggle? don?t know the difference between an 80 and a 90. The 80 starting handle goes through the bottom radiator tank.

Mine was bought on rubbers and with a pair of spade lug rears. PTO shaft was not fitted. C66 gears, as stated previously, so quite fast on the road in those days. I?ve driven it to shows over 40 miles away on several occasions.
