Flywheel Bolts Wont Come Off!

Gday Folks

Im trying to remove my flywheel bolts but with no luck. Im using a 19mm socket over them and originally tried to remove it with a repco breaker bar but to no avail.

So far Ive tried 2 different Rattle Guns and 2 different Compressors and had no luck what so ever. Ive hit the bolts with a hammer and still no go with the rattle guns.

Right now ive got my front pipe bolted to the flywheel (pressure plate bolts) so that the flywheel wont rotate (stuck against the chassis rail) and still it wont budge.

The car is only on ramps at the moment - do you think a metre long breaker bar would do the job if I got the car on a hoist?

Cheers,

JK

Like above,

I've just done my flywheel, clutch (R33) on stands, got it of with a bit of force. I used a big torque ranch that you use to bolt up engines with and off she went... :(

Rattle guns are not always good. If your using a standard size ranch just put a pipe on it as big as you can find that fits under the car and you should be ok.

Cheers,

Alex.

Would be a lot easier on a hoist.. you can't get decent leverage with the car on ramps/axle stands.

I remember trying to change the pulsar's gearbox oil and I even jacked up the end of the ratchet until it was just twisting the engine on its mounts.. nothing. gave up and let the mech do it and it took him 3 big goes at it with a breaker bar to get it undone.

I ran into the same problem on a converted s14 engine recently. The japs must be mad for over tightening flywheel bolts. Combined with loctite they take can take a lot of leverage to crack. We managed to crack the bolt in the harmonic balancer before some of the bolts in the flywheel as we had the engine locked off that bolt originally :P

On the flip side, removal of the stock flywheel on my rb was a piece of cake with a short breaker bar and socket

yeah, sounds like they have been tightened to death.. as the torque on them is not stupid. I removed my old auto flywheel with just a standard breaker.

Tightening them too much can actually have the opposite effect, they stress, and can fracture. Fractured flywheel bolts can get very nasty. Don't over tighten when you do put it back on. The torque settings are in the service manual (that cannot be asked for.. )

J,

Did my flywheel recently - 3 bolts came off with the rattle gun, the others required a slug with the hammer first before the rattle gun worked.

I've found lots of stuff stupidly over-torqued on my car.

HTH,

Kot

      Mistakes were made, my R34 Story

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
