Komatsu D21P-5 serial 45515 Engine 4D94-2 casting or serial on block 15352
No problem right?
Block tunnel bore is 75.75mm - I believe this is .75 mm beyond spec. It is round and had a non Komatsu PN# bearing installed which would work great if the crankshaft had not been turned down to 69.5mm I belive it's been line bored oversize for whatever reason. Not the standard way of doing things but this is what i have. I desperately need a set of main bearings . Komatsu .5mm bearings are 2mm+- too small due to the increased O.D.
I can't find any supporting information on a standard block bore size of 75.75mm maybe someone can help me there. I really need bearings and i find nothing in the catalogs available to me. Any help is beyond appreciated as i have called, surfed, until I'm out of ideas . As a lurker around the site I thought if someone can find them or point me to them it will be here. Thanks for your help and good day!
Thank You
