400 7fb jwac 3406b cat problem after rebuild

Cat can, but around my parts there are some independent guys that do it just as well and cheaper. Call or ask around local shops. Might talk with someone that works on heavy equipment too.

 

I’m guessing you’re in West Virginia?

 

@OLDSKOOLERnWV may know someone that can come to you and do the machine work.

 

If I recall correctly, around 0.010 is all Cat states can come of deck. Upper inserts, water hole erosion repair, clean up resurface on block deck should outlast you if done properly! Let's see what block looks like.

 

Those blocks will last just about forever if they don't have a catastrophic failure. I just had a 92U 3406 at a machine shop. Engine's 40 years old and that was the first time the deck had been cut. Only reason I had it cut was due to some minor errosion around the coolant ports. Hell the main bores have yet to be cut oversize or the original crank has yet to be cut to its first undersize.

 

Standard height of production block is 16.750" +/- 0.006". Minimum height is 16.733". Cat states minor erosion can be cleaned up if doesn't exceed 0.011".

 

What neck of the woods you in? I’m close to Huntington myself.
