My rebuild thread
Well against all common sense and good judgement I have decided to rebuild my own motor. I tore it down today and found exactly as suspected. The front rotor nuked an apex seal which destroyed the rotor and nuked the front housing. The irons look like they might be ok but I won't know anything for sure until I take some measurements. I planned to have them machined anyway so I guess that's ok, and I planned on replacing both housings also. The rear rotor is in great shape so that's good!
I have to tell you, that front bolt is my arch ******* enemy!! It took an hour and a half combined and a 3/4 " impact to get that god damn thing off, plus I broke 2 impact sockets
!! I took a bunch of pics that I'll post tomorrow, I'm too tired to do it tonight.

Have fun in your rebuild, take your time, measure twice......
On another note...My IR 1/2" impact gets them off, no problem. You need to buy better tools or you need more air....LOL.

ok here are some pics.
Here is a pic of that evil bastard known as the front bolt.
this is the rear housing looking to be in pretty good shape
the rear rotor is in good shape but I noticed the outer oil control ring was bad so the whole side and 3 faces of the rotor had pretty good oil residue on them
this is the only mark on the rear housing, you can see it but you can't feel it. No worries as I intend to replace it anyway.
Now here is where the problem starts. 1 apex seal was broke and 2 were pushed in. I assume this is what people mean when the talk about a stuck apex seal.
here'a a shitty pic
this is the rotor housing and front plate, the housing is fucked but the plate isn't as bad.
I'll post better pics of the good and bad rotors later.

Ok I just took some measurements on the rotor I believed to be good and here's what I got measuring the maz rotor width at the 3 points specified in the manual
point a =3.2000
point b =3.2090
point c = 3.2195
that makes the difference between point a and point c .0195.
If I am reading the manual correctly I am allowed between .0043 - .0083 difference between the 3 points thus making this rotor unusable? I can't wait for bruces video to get here lol.
Edit, I think I misinterpreted. Of those 3 measurements I now believe I am supposed to take the maximum and compare it to the housing width and have between .0043 - .0083 clearance with the minimum usable clearing being .0039. On a side note I am now considering reusing the rear housing if it is forund way within spec.

Yeah I've heard nothing but good things about him. Well the irons are at Racing Beat getting lapped and ported. Turns out UPS cracked the rear iron so I just bought a new one with ups's money lol. RB should have the iron's back to me in a few weeks then I'll start worrying about housings..
