Loose sleeves

[pete landon]

I've got a 9n,I found alittle oil in the raditor.So I pulled the head and the only thing I could come up with is the sleeves seem to be alittle loose.Does anyone have a quick tempo fix for this besides replcaement,I've heard some things but thought I'd try the experts first.

First off the sleeves are not related to the oil in the radiator. Small amounts are not unusual in these tractors - usually just an oily film on the surface.

Second, how loose is "a little loose"? They should not move at all. If the pistons push them up out of the bore they need to be fixed immediately. Loctite makes a number of retaining compunds that can be used for this pupose. A small band (1" or so wide) applied to the top of the sleeve should be sufficient. Then drive them fully home - don't dawdle - the retaining compund begins to cure as soon as the oxygen is cut off. Working time is only a matter of 4-5 minutes once you start them back in.

Pete......while yer sleeves need to be tite in the block, they ain't the reason you found some oily film floating ontop in yer radiator water. Yer headgasket is the reason. Combustion gasses by-pass the poor headgasket seal and float ontop yer radiator water. REPLACE yer headgasket.

Headgaskets come in 2-styles, metal (for new engine rebuild) or "fiber" for replacement.

As fer yer "loose" sleeve, locktite makes a sleeve glue, but you haffta gitt-itt underneath the sleeve rim first. Which means fighting the friction of yer piston rings. Which means dropping yer oilpan so you can unbolt yer pistons from the crankshaft. All-in-all, you really don't want to go there.

REPLACING yer headgasket is really all you need. Remember to re-tighten yer stud-nutts (55ft/lbs) after about 1/2-hr of engine warm-up time. ......Dell

I found the oil when I pulled the radiator and after all the water came out then what could have been as much as a half to t 3/4s of a quart of oil sluge came out.Thats when I thought it mite be a good idea to take a colser look,so I pulled the head,WOW what alot of carbon build up,after cleaning all that stuff up then I tried pushing on the sleeves just with my fingers and could see a tiny bit of movement on all of them so I figured that was the trouble,the head gasket looked good and it was the fiber type.So you say just get a new one copper coat it and stick her back together.If thats it then I'm a happy camper.

If the sleeves are visibly moving they need to be fixed - these tractors have a nasty habit of dropping sleeves (broken sleeve in crankcase) and if you expect the head to hold them in place you are tempting fate. Crank the engine over and if the pistons push the sleeves up out of the bore apply some Loctite to them as I described above and drive them back in flush with the top of the block. Wait about 15 minutes before cranking engine again after "gluing" a sleeve. Simple, cheap insurance.

A half qt+ of sludge is not normal but it wouldn't be the first old cooling system I've seen with that sort of garbage in it. Flush it well and refill with fresh coolant.

Pete, I had a slight noise in my 8N, turned out to be a loose sleeve. I discovered it too late when the flange on top of the sleeve broke off, the crank cleaned off the bottom of the sleeve as it dropped down and I was out of business. I locktited it back in, (didn't know there was a special locktite), and all was well. This was about 36 years ago. It is still running well.

36 years without an engine rebuild....

Must be a show tractor, or you don't need it much.

I agree with the others.. glue the sleaves in, then repalce head gasket, and flush cooling system.. then just watch it for a while.keep an eye on the oil as well.

Dunk, I use it almost every week, and often for days in a row, pulling logs out of the woods, buzzing, brush hogging, grading, you name it. If you saw a pic of it when I bought it and now, you would know it was well used. I also have a '53 Ford F350 pickup that is used a lot in the summer and it dosn't need a rebuild either! I've had it since 1982 and am the 3rd owner.

By the way, I did not mention in the first post that I only rebuilt the one cylinder, not the entire engine. Coincidentally, I rent space in a commercial building to an engine rebuilder. He has done many flathead ford v8s and some 9n-8n"s. If I needed a rebuild, the shop is just across the road. It goes by the name of Rt 38 Machine shop.

Ok, now you have done it....

I want to know what kind of oil [b:803882b42e]you[/b:803882b42e] use.

(I guess the topic will go downhill now)
