Reuse flywheel bolts? yay or nay

[EV0300]

As above want to know peoples thoughts i know certain vehicles are single use but i cant seem to find anything on mitsus.

G'day. I have used flywheel bolts twice before and, fingers crossed, the flywheel is still in the car. I use high strength Loctite on the bolts when I put the engine for the rally car back together.
Cheers

used mine a few times, torqued to spec, no loctite

 

[BMGTZ]

built many many engines and never thought to change these to be honest......also never had a problem

 

[SKMsport]

I have re used mine a fair few times.

I am now changing them with the items due to fitting a new flywheel.

ARP also do some to suite. But I think ill stay with genuine Mitsubishi items.

The best thing to do is probably just get new ones, then at least you know where there at.

Cheers guys thanks for the replys

I have read threads from some of the forums in the states who say stay away from ARP flywheel bolts as they are renowned for backing out. I can only imagine the carnage a flywheel would cause if it decided to let go!

Could end up being renamed Neil if it lets go !

3 of the 7 bolts are jammed on real good. even a high power rattlegun isnt getting them off.. ive soaked them in wd40 overnight aswell any other ideas on how to get these pain in the ass bolts off. I think the mechanic that tightened them last time just tightened the fuck out of them with a rattlegun when he did the clutch last..

If ya cant get it with a breaker bar, throw a length of tube over the end of it to make it longer, cross ya fingers ya dont break em..

3/4 rattlegun or a bluepoint or ingersol 1/2 drive.
Even wind up the air pressure a bit

 

[EV0300]

Tried both of those things

 

[BYBY5L]

Cant be trying hard enough, lol,
get a longer pole if ya still cant

 

[4piknup]

If you havent split a socket, you still got some trying to go.
Just dont burr the bolt head by letting it slip

 

[EV0300]

i did split one,and it slipped and has semi rounded, any thoughts on heating them with a torch?

 

[Ian91]

You could try that or freeze spray maybe

I hang a chain on the flywheel where one of the pressure plate 8 x 1.25 bolts are, then poke a larger Phillips head srew driver thru a bell housing bolt hole in the block. This locks the flywheel solid when you attempt to crack the flywheel bolt with a "long" breaker bar . It may need a tube on the end to lengthen it. use a short hex impact socket and lean away. its probably been rattled on with Loctite ! You may have to give the flywheel bolt a bit of heat from the oxy to help stretch the bolt a bit.

 

[EV0300]

spoke to the mechanic that did my clutch last time he confirmed it was loctited and rattled... ive gotten a longer pole about 1.5m all up and ill give it another crack this arvo, but the bolt corners have already started to round off so im not liking my chances.

 

[blackvr]

I use a special short impact socket that has been ground down on the hex opening. This ensures maximum hex engagement on those OEM short height flywheel bolts. It gives you another 2-3 mm of engagement, and really helps in not rounding off the head of the really short flywheel bolt.

 

[4piknup]

Sounds like a good idea↑ ground down single hex...
