Have a WD45 with serial #WD18690, Engine number is 45-47802G. The repair manual we have says there is a difference between the engines after engine number W45FG1001. As you can see our number is nothong like this so we don't know if it is before or after. The engine was rebuilt by someone, but had bad oil pressure and and probably dirt in it when reassembled. All main bearings, rod bearings and can bearings are now shot. The Main caps had one shim under on of the bolts. THis would seem to indicate an earlier engine, but not logical to have just one shim and only under one bolt.
Can anyone help me with identifying this engine so we get correct parts and rebuild it properly?
Have thought about just assembling by using plastiguage to check mains and rods. Would .002 be about right?
Thanks so much in advance.
