It would seem I bought a red headed step child here. Even going to the local Massey dealer they could not give me any detailed information. Serial no. not listed. I need to purchase shop and parts manuals but need to know if they will apply. I believe it is a mid 70's MF40 Industrial. It has a MF32 Loader S/N L810010847 with dual bucket cylinders, 3 point hitch arms, with all controls. 152UA Perkins, Original S/N 389469D per Owners manual. S/N on block is 152UA131161D. Std clutched xmsn with a lever on the left for forward and reverse. Looks like the previous owners bought a short block, no rust on the unpainted block but head is yellow. I have an issue with compression gases pressurizing the cooling system, I hope it is just a head gasket. I bought the gasket but do not know the torque for the head. Any help would be greatly appreciated
