We just put the short block together but I can't get the rear stationary gear installed. I tried to rotate the e-shaft but it only moves about 1/8 turn before stopping.
Does the stationary gear need to be installed before the e-shaft and rotors can be rotated? If not, why won't the spin?

No suggestions.
I guess I'll tear it back down tomorrow and see if anything appears out of the normal.

loosen all the through bolts see if it will spin then if not the front rotor might not be seated all the way on the front stat gear if so make sure all your apex seals are the correct length and your housings are not warped my apex seals were all to long on my build and wouldnt allow the motor to spin

Thanks for the input. I'm going to disassemble the keg and check the things you mentioned. Hopefully something easy will become apparent.

I don't usually name my rebuilds but, because all of problems that have occurred during this rebuild, this is Project Angie. I should just package up all of the parts and sell it.

Don't move the eccentric without the stationary gears installed! Only a few degrees in either direction is acceptable. It won't move further because it will bind!

It can sometimes be a pain to get the stationary gear in. Where is it stopping? If the gear teeth don't mesh, turn the eccentric VERY slightly in either direction until they do. You may need to rock the gear a little bit. It is a VERY close tolerance, so it may take some wiggling.

Thanks Aaron, after I had already removed the rear iron, I started wondering if the stationary gear needed to be installed before the eccentric was rotated.

I did find a small problem though. One of the longer apex seal springs was bent. About 3/8" on the end was bent up. I pretty much straightened it out but now I'm wondering if it is still safe to use it. It was a little more bent. The spring on the left is for comparison.

Yea, I wouldn't use it. It just looks too bent to me.

Thanks, yea, I better not use it. It was actually bent more than in the picture and I straightened it out with pliers. I should have some lightly used ones laying around but I can't find them. They aren't expensive to replace but I hate to buy a whole set and wait a week for them to arrive.

Mazdatrix has the seals on their site for sale individually. So, I ordered a couple. I figure that if they are in stock I should have them by Wed.

Wonder if the apex seal spring was bent by trying to turn the e-shaft before the rear stationary gear was in place or by something else?

don't rotate the e-shaft to line up with the rear stat gear, alternately use a plastic dead blow to tap the gear lightly into the block, if the gear doesn't mesh right away use the hammer to rotate the gear slightly by tapping in the crescent cutout in the gear to mesh it all. again tap the gear down into the rotor then twist the gear again to line up with the alignment pin.

rotating the e-shaft without the gear in place the rotor has no timing and will bind up inside the housing and can even drop the seals out.

or a new spring from the dealer will cost you probably 7-15 dollars

I thought of going to the dealer but the closest Mazda dealer is 45 minutes from me.
