M103 Transmission Bellhousing Bolt Size for Engine Stand
 

I hate to ask this since I looked up this a few years ago to put an M103 on an engine stand and found the answer on this forum. But I cannot seem to find the answer today.

What is the bolt size and thread pitch for the bellhousing on an M103? I plan to go to the hardware store and buy 4 bolts for an engine going onto an engine stand.

If I had to guess I'd go with 10X1.5

All i find is M10 lock up to 56 NM

Sorry to thread-jack but do you support the engine with anything else, or have you found that the m103 mounts to a stand fine without need for additional support? I’m looking for a stand to put an m103 on and found a thread suggesting the need for extra support. Seems like some use a bottle jack. Thanks.

I have an M103 on a 1000lb engine stand at the moment. No problems with needing any extra support.

Your guess was right. Confirmed that it was M10x1.50

Thanks!
