damn apex seal
hey all
since i just got my flywheel off i started to fly through my engine and now i am on the first rotor housing and its all apart. BUT i noticed that only one apex had something wrong with it, the apex seal only had 2 peices yet mine is an 88 that came with the 3 peice seal, i just dismissed it as complacency of the person that rebuilt it before, but then i saw my worst nightmare. the housing had a deep gouge ALL around and theres little holes in the housing from where the seal i guess exploded. and the rotor has some damage too, but im not sure if its enough to render it useless. so from what you see do you think i could salvage the rotor?

The rotor doesnt look horrible, just make sure theres nothig there thats going to interfere with the housings or irons went put back together. From the pics it looks ok. Basically smooth it out the best u can. And cleaning them is the best part. Have fun. Lets see the housings too.

Haha, wtf? ^
Your rotor housing is junk. Any imperfection other than normal 1/8" of grooving on either end is not really acceptable. Your rotor...well, if the damage has interfered with or pinched any of the side, corner, or apex seal slots, then it isnt useable either. Apex seal slots can sometimes be filed out or even milled to 3mm, but corner and side seal slots cannot be repaired most of the time unless it's VERY light distortion. That doesnt look too bad though. The scratches on the face of the rotor don't hurt anything, the rotor floats and never touches anything so those scratches won't hurt, if the seal slots are all okay then it's fine.

damn is that bulge in the housing supposed to be there?
also how long were you running it with the seal busted?

well the front iron doesnt look good either it has some deep grooves and the coolant seal passasge is broken too, making coolant seep into the housing causing the front rotor to rust and well be a bitch at taking apart. but luckly i have patience. is it better to buy new hosuings/irons or buy good used ones?

At a cost around $400 each for new or $100 each for used, what do you think?
BTW, if the rotor is rusted enough, the seals won't come out of it, and you'll have to buy one of those, too. This is what happens when you have a water burning motor that you just shut off and let sit for a few months. IF you put oil or atf or something into the chamber and turn it over every so often this will displace the water and prevent rust, making the rotor useable in the future. Many people make this mistake, and often the rotorhousings and eshaft are the only parts that come out of a water seal motor that was left to sit for a while.

but all i wanted out of the motor was the rotors anyway so its no big loss anyway
