Thanks mate is .030" the thickest shim available?

Also can the shims be stacked?

It is not advisable to stack shims, but my engine machinist has cut thicker shims and used them, but it seems like we were talking about a 3306.

His opinion was to avoid the thin shims for fear of exhaust gas erosion, but I always figured that Cat had done a little research on that when they designed them.

As always great information guys i guess i may have to find a laser cutting place to cut out thicker shims or my other option is caterpillar will machine up inserts but i dont have a spare arm or leg to give up lol

Hi Justin,
maybe contact Head Hunters in Dandenong and see what they offer. They are now part of William Adams but did all of our engine machining work for years and may have done your block and supplied the shims to suit back in the day.
Cheers,

The first task to do is drop all the cylinder liners in the holes and check the "Dip" facing up the block involves topping the pistons so more work, the liner shims can be stacked if you have to but avoid using 1 thick shim and 1 very thin shim, if you do stack them use 2 shims as thick as possible to attain your height target, is this a 4"1/2 or 4"3/4 bore engine?
