M10 x 1.5, length varies depending on your stand. Which brings me to the next question:
I just pulled the OM603 out of my 300D to replace the timing cover, and do some other assorted maintenance. I was going to bolt it up to my Harbor Freight engine stand, but then I noticed the bellhousing bolts are awfully small... M10! Is it safe to hang all the weight of a complete 603 from four M10 bolts? The last thing I need is to break off the back of the block or something...!
Am I just being paranoid?
Best regards,
