135 engine rebuild

[chris787]

Hey everyone, looking some advice please,

I have removed and stripped the engine block from my massey fergusom 135, I sent it to a local machinist to have the old liners removed and the block resurfaced.
The machinist has advised to boreout the 3 cylinders oversize and he will insert 3 new liners and for me not to use the standard sleeve inserts. He says it's the way he allways does these engines and he doesn't rate the push in sleeves at all.
What's your thoughts on this, most advice I see is that these cylinders shouldn't be recorded, has any one done it tgis way?

Secondly the crank has some scratches and will need reground, new cranks armt that expensive would it just be handier putting a new crank in and keeping the bearings standard?

Check to see if the block is a Perkins diesel block. I know some of them had the Perkins diesel block with gasoline heads and crank.

It's definitely an original diesel block, tye original cylinder head is done, I've bought a new cylinder, my question is it necessary to bore tye cylinders oversize instead of using the slip in liners?

I‘d trust the machinist on this one. He sounds like an old-school guy who knows these engines inside and out.
Boring them for new, thicker liners is a top-notch repair, probably better than the original slip-in ones. A lot of the best shops do it this way. The standard "slip-in" liners are fine, but they are very thin. If the block itself has any wear or pitting from over the years, just putting in new slip-fit liners won't fix the block underneath.
