Ferg uson Tractor

Harry Keller · Jul 13, 2014

Bought what I believe is an old TEA20 ferg tractor with 4 cyl sleeves and 4 pistons..I removed head and having valves redone at machine shop.Purchased rings which were not with pistons and installed sleeves and pistons and torqed rod bolts ..Now I wonder if these sleeves and pistons plus rings are for this engine as it looks like maybe 3 different bores available for this engineCan I get a number off the engine as to what engine this woulthou should the sleeves be above the engine block as not having measured these they seem to be above the block about 25 to 40 thou..Also pistons are 5 ring 3 comp and 2 oil..

Can't you compare the old parts to the new ones? Check for part numbers stamped on top of the Pistons? Were the sleeves exactly the same OD and length as the old ones? Over bore kits for these engines are quite common. Did you check the end gap on the rings. Did you plasti-guage the bearings? There is a lot more to properly rebuilding an engine than just throwing in the parts and hoping they fit.

That is high on the sleeve protrusion but did you clean the counter bore real well???? You can check the protrusion with a straight edge and a feeler gauge.

IF I remember correctly that engine has dry sleeves. They can be a real bear to get seated correctly with out a sleeve puller.

As for the number of rings. That depends on the manufacture. Some have four and some have five. So without know what brand of piston/kit there is no way to know what you have.

Did you check the end gaps on the rings? If they are not the right size, that will tell the story very quickly. Also, as previously stated, plastigage the bearings! While clearances give you a decent amount of leeway, if they are too loose or too tight, you will find out the hard way if they "were" right....
As for the sleeves being above the block 25 to 40 thousandths is a big spread. At that height, I would think that they might interfere with the sealing of the head gasket. That will depend on the way everything is designed to fit. Without a manual or at least access to some service information, you are only GUESSING. To the old timer that is intimately familiar with this engine, guessing is OK. To an inexperienced guy, guessing is unacceptable.

Remember: Experience is a tough teacher. It tests you first, and teaches you after.

The TEA standard built engine is a wet liner block with a figure of eight gasket to seal the liners in pairs. too thick a gasket below will cause too much protrusion.......Sam

I had better get some specs and do some measurments before going any further ..Where would I get ring gap?/ Would measurements of old sleeves be sufficient?
