COUNTERBORE MACHINING
Blow a head gasket? A warped head may not be your only problem. Before installing the head or during an overhaul, be sure to check those counter bores and your liner protrusion with a sled gauge. We sell gauge kits if needed. If the counter bores are out of specification, it's time to machine for shims to true everything back up and leave it better than new.
Have a Detroit Diesel 60 Series with a cracked upper counter bore? Or how about a Cummins? We can machine those as well and install repair inserts which are the most effective repair.
If your inline engine has a scored or cracked sleeve/cylinder we can repair it in chassis. Although not the most ideal situation, we can do it!
