case 188 sleeves

[jim miller]

I a trying remove the sleeves with the pistons still in them.I recently picked up a case 310g loader backhoe in real nice condition other than the pistons being stuck from rain getting in through the air filter lid (not the exhaust).The lid has a small indent where the wing nut goes, all was tight but just that little bit of water sitting in that wing nut area was enough over the course of a couple of years to lock it up,so when you have the exhaust covered thats not enough.(learning experience).Any ideas. I have to buy a sleeve kit anyhow so I dont mind ruining them. Thanks, any ideas greatly appreciated

If they are dry sleeves you can get them out by running a couple of weld beads up and down the inside of the cylinder bore using a real skinny weld rod. The schrinkage of the weld metal shrinks the sleeve just enough to loosen it. I have seen this done on dry-sleeve Perkins's and it works like a charm. If they are wet sleeves, you are SOL. Set up the puller and crank a strain into it and tap, the vibrations of the tapping can loosen the sleeves.

expand on the above.. if the pistons are stuck in dry sleeves far enough down in the bore you can still use the weld technique. Otherwise you have to use the standard techniques to free up a stuck engine, only the sleeve might come up instead of the piston, but at least you have loosened it. If it is a wet sleeve, any technique to get the crank to rotate might break loose the seals. At any rate this will require patience and maybe some salty language and Zen if all else fails. Good luck.

I have used and had good luck on cat wet sleeves by welding a homemade T bar in the bore and using a threaded steel rod and a large "T" bar balanced on a pair of deep 1 inch drive sockets. I have also used a standard liner puller, instead of going to the bottom let it go down to let it cock and if you are lucky and have patience it will pull the liner., BE SURE AND REMOVE THE ROD CAP!

The 188 has wet liners and they should come out fairly easy,make sure all the coolant is out of the block,blow it out with air if you got it,take off the caps and wrap some cloth around the big end and shaft to keep the debris at bay,get a suitable length of bar and a bottle jack,put the bar up against the top of the piston past the wrist pin and the jack under it,a few strokes and the liner will pop up,stop then and wrap the shaft to protect it and keep it clean,the liner should lift out once past the seal area.

Jim,

I had to do this to the 188 in my Case 450 a couple of years ago. I made a puller out of angle-iron and heavy threaded rod. Had a picture of it somewhere...

It's a little heavy, maybe 15-20 lbs but you're welcome to borrow it if you like.
