Mf 135 diesel liners

Have you a manual? we use the I&T shop manual, about $30 at the left of the board.

A puller is essential. You can make it - I can send you a pix of mine if it will help.

I run several fast LIGHT electric weld beads up the sides of the old sleeves to shrink them. Too heavy and the weld penetrates and fuses the sleeve to the block. (How do I know?)

If you're doing this with the crank in place, PROTECT the crank journals from splatter.

Then pull them - they may still come quite stiffly for the first half way.

Replacing - wipe the sleeves clean and put them in a deep freeze for a few hours to shrink them. Clean everything, remove any burrs from the hole, remove any carbon from the top groove,insert fast, push down as far as you can, and pull down tight with the puller. Hammering will break them. (How do I know?)

Hope this helps.

I'd be interested in a picture of the puller as I think I may have two engines to do sometime. I saw one available commercially and the business end looked like a disc with a flange to bear on the bottom (or top)of the liner and was thinking I could make something similar. They are VERY brittle and thin and I don't think you could put a hammer near them without almost certain disaster.

Luckily I have an old block to experiment on. (or maybe unuckily, as I only have it because the machine had an engine blow-up!)
