13B rebuild
i just found this forum this morning! great place! this is my first post here, but i already have a technical question. i've owned three -7's (currently without one ), and i'm tearing down a 13B out of an '86. i can't get the flywheel nut off! it's driving me crazy! i've bent two pieces of steel angle, and broken two torque wrenches trying to get this this off.
is there any sort of lube that'll seriously loosen it up, or do i need to take the engine to a shop to have 'em impact it?
btw, in addition to my rx-7 experience (or because of), i am planning on powering my airplane with a rotary!!
thanks!!

do you have a compressor and air tools? if you have already tried an impact wrench then do what i did... use an air chisel. tap the nut at an angle and it will loosen it.

i do have a compressor and lots of air tools, but no air impact wrench. could probably borrow one though. never thought of the air chisel idea. i may have to do that, 'cuz this thing is ON THERE!

i don't know why i typed torque wrench...i broke two breaker bars. one napa and one craftsman. both of them were 18" bars. i'll have to borrow an impact, but i'm sure that'll get it done.
btw, sweet avatar!

oddly enough, the e-shaft bolt came loose easily (relatively speaking, of course). it should be torqued higher than the fly nut, but not sure in this case...
now i'm having problems locating a 54mm socket. i borrowed one before, and it's not available right now. i went to five different stores to spend the $25-50 for a one time use socket, and can't find any. sears usually has a 2 1/8 (same thing), but are out of stock right now. maybe over the weekend. i will try heat when i find a socket to use.
anybody want to send me one to borrow (3/4 inch drive)? i'll pay shipping both ways...

this nut just WON'T come off!!!!!!!!!!! i think it's time to it.
impact didn't work. somebody torqued this thing down WAY to tight. i'm gonna have to get a cutting torch and slice it off...

If you were any closer I would let you borrow mine. If my car is done at aspec any time soon I will pm you. I have the 54mm mac socket and my 1/2 impact. if all else false you can rent a 3/4 impact and try again well if that doesn't work god help you my son.
good luck with your rotary powered aviation project you and my father should get together hes been talking about putting a rotary in a RV6 since he got his first ride in my FD. I will be flying with him down to schwamburg in his cherokee 180.

well, i FINALLY got the damn thing off tonight!!!!
i went at it sort of unconventionally...with my dremel tool. i just decided to cut it off. using the cutoff wheel, and a chisel, i busted it off. this engine is beyond repair anyway, so now it's just a matter of principle in getting the thing torn down to see if there's anything salvagable inside.
thanks for all your recommendations!!!
rocking rotary, have fun tomorrow!! looks like a nice day! btw, tell your dad i'm building an RV-7. not sure on the engine choice right now, but i'll keep you all in the loop if i decide to go with the 13B.
