Well just the o-rings is duable (i think). The hardest part looks to be removing/reinstalling the flywheel. Does anyone where where to buy that huge socket?



The apex seals requires "alot" of attention to detail but I won't mess with the rotors (didn't have compression problems anyhow).



I can actually see the orange o-rings squeezing through the cracks in between the housings and I have no idea if it means their warped or the Mazda assembly people were retarded.



I can't test any of the housings for warpage, so i'm not sure if i'll take those to a shop for testing or not.



The very last step testing the excentric shaft for play, which I can't do either.

if you can actually see the O rings (theres a gap between the housings) you might have tension bolts that came loose and/or broke.

buy a 2 1/8" socket from sears

And a 3' steel pipe extender from Home depot

It will look good when ya finished....

I seem to recall saying this in another post recently....



It's silicone RTV that is used with the coolant seals during assembly that you're seeing "squeezing" out between the housings.



I have NEVER ever seen a coolant seal get pushed out between housings in over 50 motors that I've done... https://www.nopistons.com/forums/pub...#>/biggrin.png



Mind you, we are talking about rotaries here, so anything's possible! https://www.nopistons.com/forums/pub...IR#>/boink.gif

If you have a true surface (machined to be flat) and some feeler gauges you can check for warpage. If you don't have a true surface, go to a machine shop and have them make one for you. They are easy to make, so it should be cheap. If you don't have feeler gauges, GET SOME, you shouldn't be rebuilding your engine without the proper tools.



Buy a stand and a dial indicator, they are not that expensive, and they have many uses. If you rebuild your motor another time the purchase will be more than worth it.

I'm rebuilding my engine with 113k miles. how important are the tests for wear if the only problem was a blown apex seal? i'd rather not buy precision measuring tools if i'm only gonna use them once. would it be risky to just do the visual inspection and feeler gauge tests on the rotors and housings?

You could get away with it, but you never know. I mean, it's your money, so if it is worth it to you to risk another rebuild, then go for it. I don't think I would do it without checking. See if any of your friends have any of the tools.



If you are gonna have this car for awhile, or you are gonna have more rotary vehicles, the tools would be a good idea to pick up as you could use them forever....you could always sell them on ebay when you sell your rotary vehicle, or include them with the sale https://www.nopistons.com/forums/pub...IR#>/dunno.gif

usually if it passes the visual tests its good, but once and a while you can get bit
