- New Holland T1030
I'm doing a complete rebuild of the engine for my New Holland T1030. The engine is a Shibaura S773L. The block is cracked in several places and also has a hole in it (threw a rod), so I'm replacing the entire block. I'm not a diesel mechanic by any means but I am willing to tinker and learn. I was able to find a used, but good condition, block. That being said, the original engine from my tractor is an S773L M662 whereas the used block I acquired is an S773L M661. As far as I can tell there is only one minor difference. The M662 has a small gear that is located next to the Cam Gear. The M661 block does not have a place for this gear. Also--I can't figure out what that gear does. It doesn't seem to engage or turn any other parts but I know I could be mistaken. The attached pictures show the gear in question and the difference in blocks. Anyone out there have any idea what this gear does? What are the chances I could rebuild the engine in M661 block, without this gear, and not have any major issues? Otherwise, I suppose I could have the block machined to receive the gear...right?
Thanks!
