560 update from last night--dry sleeve insert explosion-Why?

NolanJae · Feb 18, 2011

posted a question about where to start looking for my problem with my 560 diesel last night. Well I dropped the oil pan and found most of a dry pressed in sleeve (in a hundred pieces of course) in the pan. odd thing is it was the second sleeve from the back of the motor (towards the seat). Why would a sleeve let go? Why would that one let go? If someone rebuilt it in the past could the sleeve have been driven in too far to where it cracked the top of the sleeve? I've owned the tractor for a year and used it often but why now. The crank looks to be intact... From the bottom I can see that that the bottom ring on the piston is intact and on the piston. How messed up will the block be? Will I automaticly have to bore each out and order oversized sleeves?

The most likely is a loose sleeve in the cast block bore. The thermal loads when it is not as tight, and the ringing (as a bell) can stress crack the sleeve at the point where the retaining ring meets the main part of the sleeve. The sleeve creeps lower in the cylinder until the top ring expands out over it and drags the sleeve into rotating parts. Jim

Makes sense. So call up the machine shop and get the check book out!

Thanks

Is the 560 engine one of those that didn't use the exact same sized sleeve in each cylinder? Is there some sort of number or code stamped into the top of the block right next to the cylinder with the damaged sleeve? It is highly possible the previous owner did not know, and installed a "standard" sleeve set where one of the cylinders SHOULD have had a slightly larger O.D. sleeve.

with the years of oil/dirt build up I did not see anything but I did not look either. Would that be a number stamped by a machine shop or would that be stamped at the factory per each cylinder?

It would be stamped at the factory, but only on the cylinders that are not standard. There may be more than one cylinder, there may be none. I'm not an expert, we need "tractorvet" to jump in here.

Nolan! This is nothing new the 460 560 and some 706 with 282 would do just as you have said. Problem is 2 fold sleves did not fit tight enough abd the sleve did not have right undercut just under lip so they would crak and in time you find them in the pan. There was some different OD's to mahe them fit better. All I ever did was to paint the out side with aluminum paint. You can see if you can still get the bigger OD sleves. Most likey the block is oh.

It is (I think) Letters
Nothing is spec. then A B C and D each larger (possibly by .0005" increments) if it is loose and drops in it is going to break. a pushed in place fit is OK a light hammer tap on a hard wood block is good. Jim

I was a little kid at the time, but our first 560D developed an odd tapping sound while still under warranty. The local dealer tore it down and replaced the sleeves and pistons with the correctly lettered ones. It seems that some of the early ones got out of the factory with the wrong ones in them. I remember that they put a bead of white lead around the new sleeves before they drove them in, which was the recommendation from the company. Ours ran for years after that with no problem. This was a tractor that had the rear casting marked meaning it had had the heavier gears installed before delivery, so it had to have been an earlier tractor.

Early engines had a looser fitting sleeve than the later engines. Some sleeves could be installed all the way in with just hand pressure. The sleeves are held in place by the head gasket instead of friction in the block bore. Most of the time you are better off getting the .002" oversize sleeves and then honing the block a little if they are too tight. If the sleeve flange height varied too much between adjacent cylinders it could allow a low low sleeve to move in the block. There are shims available to adjust sleeve flange height for these early blocks.

If ether was improperly used to start the engine it could also lead to cracking of the sleeve flange. Ether should not be sprayed into the intake unless the engine is already cranking over and never used if the glow plugs are being used. This type of breakage is not unusual with engines that have seen a lot of ether to start them. You will also find it in the later engines with the press fit sleeve and in the D361 and D407 engines. Sometimes when a head is removed you will find evidence where a piece of sleeve flange has broken off and left it's mark on the piston and head.
