Z134 Sleeves

I had initially tried bumping them out with a hammer and 2x4 whacking against the bottom of the sleeve but soon gave that up. Others have said it works, and good for them.

When the new sleeves go in, there are seals that go into the grooves in the bottom of the sleeve. The I&T manual should say something about lubing them slightly and being careful not to nick them when inserting them. The Z134 is a wet sleeve engine and antifreeze should stay where it belongs, not leak down into the oil pan.

If you take the time to make or borrow the proper tools it's pretty straightforward.

The smaller step keeps the disc centered in the sleeve by fitting in the id of the sleeve.

Most anybody with a metal lathe can buzz that out for you in a short while. I got mine made from steel about an inch thick, but aluminum would probably work too, at least at that thickness.

If you wish, the cross bar on the top which the redi rod goes through can later be used to (gently) seat the new sleeve in the block. It'll need to be long enough to accomodate a couple holes for head bolts or studs. But that's kind of gilding the lily. If the sleeve counterbore is nice and clean and the seals are appropriately lubed the new sleeves should go on in with little problem.

Those dry sleeves are set firmly. We loosen them with a half-dozen VERY LIGHT passes bottom to top with a welding rod. Shrinks them slightly.

VERY LIGHT and fast - the sleeves are less than 1/32 thick; if you burn through you've got a real mess! (Sleeve welded in place, burnt block, engine out, re-bore and resleeve..... Ask me how I know.....)

Start about 1" from the bottom, to leave undisturbed sleeve wall for the puller adaptor plate.

Protect your crank from splatter!

If you have a lathe you could make one up, or just jigsaw a dummy one out of wood and see if it would fit above the crank.

The basic idea is pretty simple, the od of the thing is a bit smaller than the od of the sleeve. There's a step machined around the outside so that it centers in the sleeve.

Lots of people seem to have the old touch with the all purpose 2x4 and hammer. I just was a lot more comfortable pulling sleeve with a puller. Those seals seemed to have a good bit of drag to them, and it wasn't the kind of deal you could whap once and have it come out.
