As shown by title, I have just taken out my engine for a rebuild but have no clue where to even mount it to work on it. any tips and pictures would be greatly appreciated, this would also be my first time working on engines in general and have never used a engine stand.
I just have a standard 1000lbs engine stand with 4 small arms. I don't have bolts as well, so what kind of of bolt should I buy to mount the engine, or is using a engine stand even necessary, Can I rebuild it on the table?
My main concern is torquing the oil pan as its gonna be hard to do on a table.

Thank you

 

The 4 small arms are freely mounted in slots. They can pivot and slide to any angle or diameter. Tip the first: mount the yoke to the engine before mounting the yoke to the stand; much easier to align one hole than four that move around on you.

Using that crucial bit of data, it should be much easier to mount the arms to the yoke to the engine with it on the ground/bench/cherry picker.

You'll need long bolts for the engine side, and slightly less long bolts for the yoke side. Take a representative sample of yoke arms with you to the hardware store, and make sure you have an idea for how thick the yoke plate and back of the engine are, and add the full width of the nut you source. A FEW extra threads never hurt anyone, but too many can cause their own problems.

All this said, rotaries are assembled standing on the flywheel end rather than with the crank (eccentric shaft) parallel to the ground. Lacking a purpose made stand mount, rebuilding on a table, the ground, or a Home Depot bucket might all be options that make your life a bit easier.
