I have a oliver 1800C diesel serial# is 139002-844. It has a cracked piston skirt on the #2 cylinder so i pulled it out and tore it down. The confusion that i have is that i thought that all 1800C had the 310 Waukesha. But after i take the head off it has a flat top pistons in it? I am need of help getting this identified to hopefully get it back together. All the casting numbers below were taken off the components.
The cylinder head has a 221902 casting # on it
The block has a casting # of 157329A and 221120C.
The crankshaft has the 221411 casting# which is for a 310
The connecting rods has 221407 casting # which is for a 310
and the piston has casting # of 221804
