ok, needless to say i have a big problem with my engine i just put together-it won't rotate correctly! So i open it back up, and i am able to turn the e-shaft and move the rotors around, but then it just stops abruptly at a particular place, and i can't move it further in the same direction. However i am able to move it back and forwards again and it eventually allows the rotors to continue in the 1st direction. So i decided to try a couple things:

1.take out rear rotor and see if it still gets stuck therefore seeing if the problem is in the front housing
2.take out apex seals and see if the rotors still get stuck

Well i took out the rear rotor, and the e-shaft moves freely and never gets stuck now, so the front of my engine is perfectly fine and it has good puffs. So i decide to put the rotor back in without apex seals. And it spins fine. I try putting 1 apex seal (and springs) at a time and spinning the rotor to see if this problem is related to one corner of the rotor, and no matter what side i put the apex seal on, the rotor stops abruptly.

I noticed that when the rotor gets stuck, the apex seals are not at the point where they are fully compressed by the housing, they are sticking out fairly far.


oh btw i noticed that the rear rotor can be rotated a little bit around the e-shaft journal like there is some play. i can do this without moving the e-shaft itself. is this normal since its not meshed with the stationary gear?

What could the cause of this damn problem be? :/

 

one of the side seals or apex seals could be catching on a port...or trash in the stationary gears...

 

well when i was watching the rotor get stuck i had the rear side housing off so the stationary gear wasn't on there. I'll go look to see if a side seal is causing it to stop...

 

ok well it doesn't look like a seal is catching on an intake port. what it looks like is that the rotor can move a little bit back and forth around the e-shaft lobe, a little to the left direction, and a little to the right. and as i turn the rotor it moves left a little on the lobe and the apex seal gets wedged against the rotor housing, but when i readjust the rotor (moving the rotor to the right around the e-shaft lobe) it moves just enough so the apex seal is no longer wedged. im thinking that maybe i can move the rotor to the right and put the stationary gear on, and maybe it may keep the rotor from wedging itself. Which would mean the stationary gear was a tooth off, but im going to go see... for certain...
