    Default snapped 4age flywheel bolts

    A combination of an uncalibrated tension wrench and/or, weak bolts and carelessness, has left me with a broken flywheel bolt for my smallport. We have managed to remove the broken bolt.

    Now what can i do? does anyone have any laying around? Particularly Adelaide? ASAP>?

    Should i ask for genuine toyota, or can i match the bolts at a motor traders. etc provioded they are high tensile steel and exact dimensions? Wreckers even?

    furthermore, should i replace just the one, or a whole set of 8, seeing as one broke, i dont want to take a risk with any others...if so, will a wrecker be fine or should i try source brand new?

    thanks guys

    ive torqued my flywheel bolts to spec once. the one time i did. pow. shnapped em.

    every other time ive used 2nd hand ones and just done them up TIGHT, with loctite (a debate in itself) and its been all swoit. for a while there we didnt use loctite, and ive actually heard one car i worked on the flywheel came loose

    you will be able to use a 4ac bolt instead of ge. the head is bigger, but it will fit between the 4age bolts, so you can use upto 4 4ac bolts with 4 4age bolts.

    i saw that the bolts were larger... i didnt bother taking them out... so you say i can use a 4ac bolt?

    seriously!

    theres no issues with balancement?

    and my mate said NO loctite... he reccomended a rattle gun swears by it....

    I wouldn't recommend a rattle gun, maybe on its lowest setting, but best to use a breaker bar (or torque wrench) and some loctite.

    do either, not gonna make a difference.

    i say use loctite. they do come out with some type of thread lock solution from factory on them.

    you can use a rattle gun if youre familiar with it.

    also.. im not talking from like, doing it once or twice..

    ive fitted about 20/30 4age clutches.

    New 4A-GE flywheel bolts from Toyota. Sometimes in stock, and affordable. Not something you want to take a chance with. I have bought new ones before, easy. $3 each.

    90105-10076

    Unless you are a mechanic and have done these up with a torque wrench a number of times and have a very good feel, then you need to borrow a torque wrench and do them up to spec.
