flywheel removal?

[dubber91]

what size is the flywheel nut on a 2nd gen rx7 13b engine? whats the best way of locking the flywheel to release the nut?
cheers

54mm dia, a 56mm dia transit hub socket will also work

To lock it you can use some alu or steel angle iron bar with two holes drilled, which are aligned to bolt through to two adjacent clutch cover threads on the flywheel.

Best of luck,

Paul

P.S. A nice 3/4 inch breaker bar will bend a lot less than a 1/2 inch bar and as such should require a lot less effort to undo the flywheel nut  :yes

Wav you may wanna tell him the use a mate to jump on the breaker bar tip when undoing flywheel nut.

Babz\'s ecu gave no joy so will be towing fd down very soon!

if you need any dimensions for a locking bar i can measure mine, i had to buy  a 54mm socket, think it cost me £27.00 somewhere on the net, where are you based in the country?

i also made a tee puller in order to get mine off without damaging anything. basically i followed the procedure on the rotary aviation rebuild vid.

this said remove the nut usually someone stands on the block and a friend jumps about a bit on the bar.

then attach the tee puller and tension it

then tap arount the edges with rubber mallet and it just sort of pops off.


ps the bell housing bolts are the same thread as the ones in the fly wheel, this is what i used for my tee puller

what happens if the engine is still in the car then ?

Yep that certainly helps :wiggle

And yeah bring it down as soon as you can, am running out of time to get everything done before I move.

Ta,

You will need to hold the motor somehow or else the engine mountings can break.

bollocks so its actually 54mm? just ordered a 56mm transit socket...hope it works!
i will need to lock the flywheel though what are the demisions of the bits you used guys? cheers

Don\'t worry, the 56mm transit socket works fine and is generally much cheaper and more widely available

The piece of angle iron i use is just over 1 foot long and is probably around 40-50mm across on each flat by approx. 4mm thick.

sorry your losing me! do you just bolt it to two of the clutch mounting holes, and it lock against the stud from the case?

Yeah, mount it to two of the clutch cover threads and then have it locking against the floor.

Paul

P.S. Much easier if sump and pick is already removed, that way the block will sit nice and flat on the floor.

not gonna happen, im only removing the flywheel because its a vw/mazda one! the engines in a beetle...

Hmmm, well either get a piece of angle iron long enough to rpop agains\'t the floor from where the engine is sitting or find someone with the correct tool to borrow or copy dimensions off. Of course mazdatrix in US sell one i think aswell.

Paul

[dubber91]

well its on the floor already....ill have to see how easy it is to move. two man job either way!
whats the torque setting when refitting? Is there a flywheel oil seal to check?

Steve

[oldone]

If its a 2 man job,how come I strip a motor and put it together by myself,nobody told me i need a mate to help me.!!!!! :mad:
