So I was helping my son with a TII 13BT engine that he bought from a guy that rebuilt it but didn't set the thrust bearing properly and the assembly had almost 3mm of slop/forward-rearward movement. Took the front cover off (engine is on my work bench) and sure enough the front thrust bearing behind the plate was trashed. Removed all that to prep for new parts to replace the bad. It's been over 15 years since I've built a rotary. I made the mistake of spinning the assembly by hand as we were moving it around to rest on its flywheel. Then I remembered that I wasn't supposed to move the assembly with all that off. I did though. I've searched and searched and can only find statements of don't rotate the assembly with the gear off. Nothing says what damage is done by rotating. What have I done by rotating the assembly?

The only time it's an issue is when the engine orientation is as it sits in the car and the e-shaft bolt is removed and replaced. The issue is that the thrust bearing can drop.

Your all good. Make sure to mark TDC for timing.

 

 

Did you rotate it with the front stationary not in place? If so place the stationary back and rotate till it lines up and you can bolt it down. Should not be an issue its just a matter of getting the rotor gears and the teeth of the stationary gear to line up.
