Allis-Chalmers model C cylinder liners

Hello! Trying to do a engine rebuild on a 1950 Allis model C. The new cylinder liners stand out from the face of the block 0012", the manual said it should be no more than 005" What to do? there is no dirt under the liner flange.

You need to clean up the bottom of the block real real good before you slide in the new sleeves. You also need to use a slick stuff like dish soap when pushing them in and even then you may not be able to push them down enough by hand you have to put the head on to get them all the way down some times. So yes you need to double check that you have it clean

Are you inserting them without the O rings installed?
They have to go in easily WITHOUT the O ring before you can attempt to install them with the O rings.
Turn the liner unside down and insert the flange in the recess and check the offset. LOL Bob

If you typed your spec numbers right, you are under 5 thousands as your book called for.
.0012 is touch above .001
If you are in fact at .012 install without the seals, rotate them back and forth and clamp them down with washers. Then measure. You will have problems if left too high.
Good luck.

Just had another thought, measure the flanges on the old and new and compare. Are they in fact that different? If so, could be a new part problem.
