View Full Version : Tool needed. Some sort of impact gun for about 20 mins.
Need to get my flywheel back on and am told that I need a impact gun to get them tight enough. Don't have a compressor so would need to be a battery jobby.
I will love you long time if you can help me out. :-)

Spanner and a heavy hammer does the trick :)
Would that not just turn over the engine? I know I couldnt get them off without a impact gun as they just turned the engine over.
Oooh, Also need a clutch alignment tool. :-)

Put the crunk pulley and bolt back in matey and use a a big bar to stop engine from cranking. Even if you use an impact gun you would still need to torque the bolts up FT!

They're not difficult to get torqued up by hand. Just wedge the flywheel/crank bolt so the engine doesn't turn and use a big ratchet.
As for the clutch, it's not hard to do by eye, just make sure the plate is dead centre of the cover.
Stick an old bolt through one of the bellhousing bolt holes and jam a large flat screwdriver in the ring gear so it jams againt the bolt. Then do the bolts up :thumbs:
When I was trying to get them off, I put a socket with a breaker bar on the bolt on the crank pulley, and stood on it. All I archived was a mate lifting me up when he has a breaker bar on the flywheel bolts. Took a gun to get them off.
Is torque settings that important? I have just been putting everything back on with a splash of threadlock and a sensible tightness, not so much that its loose, but not so much that its solid tight and I have had to hand on the ratchet.. Not taken anything engine off apart from intake and manifold so the important bits like crank, shells, headbolts etc are untouched as I know they're rather temperamental to tightness.
Suspension was done the same way, but I lowered the rear down onto bricks before fully tightening so the rear was holding itself up. Now that was awkward.

On a flywheel?
Well it all depends how much you like your feet I guess :wack:
as mark said, don't **** about with flywheel tightness if you can help it.
FT and threadlock minimum, ideally get a torque wrench and wedge the flywheel solid and torque correctly.
if the flywheel comes off it has a nasty habit of smashing through the bellhousing and straight into the cabin. it's why drag racers have a kevlar jacket over their bellhousing. you DON'T want to be on the receiving end of 5kgs of metal flying off at speed and spinning at 7000 RPM.
Indeed, it will be getting threadlock.
So you advice not using the tried and true method of very tight, a extra "urgh" and done, but instead fooking fooking really tight when it comes to flywheel bolts?
Does anyone have any pictures of this ring gear I need to jam? Will it be obvious once I have a look as in work at moment.
The two last posts make me want to do this properly. ¬_¬
Make sure all threads are clean before you install the flywheel. Old crusty threadlock stays in the thread and will disrupt the torque readings.
You want to get the torque right, over or under tightening the flywheel can damage your feet

Does anyone have a torque reading for the flywheel?
Rather tempted to get a torque wrench now. Rather £50 than a missing foot. Anyone know what the best range of wrench for a 13 would be as I see they go in grades.
Hmm, interesting read.
Over 100NM for those bolts, seems rather high... like the kinda number that would be quite hard to guess at.
Wondering if I could justify the money for a wrench to the girlfriend though? V_V

Service manual says 98-108 nm / 72-80 lbft for the flywheel bolts.

I got a small one and a big one off ebay aaaaaages ago, didn't cost me more than about £15 each. Done well so far, but they only get light use.
Yea thinking I will just pay the money for the piece of mind. Rather £60 now and happy motoring, than free now, 200 happy miles, a written off car and trouble finding places with wheelchair access for the rest of my life.
Fair trade off I think.

im a bit worried after reading this now lol....mine was under the car with the gearbox just off doing them up cause some wolly forgot to do them up before they put the engine in! lol. So i just used a spanner and wacked them with a hammer without locking the wheel up.
Ricky - Sorry mate but that gearbox is gonna have to come back off again :(

Parr, do you still need a impact gun? my snap on one will do over 200 nM in about 8 impacts if you want to use it but i cant get to you till the weekend
Thanks Joe but I grabbed myself a torque wrench now. Going to wonder around the car making sure all the bolts are torqued to spec, spesh on the suspension as I imagine that could make a difference?
Need to get you down our unit though, pay you in cider for free labour? :-)
Good news! :D DONE!
Threadlocked and each torqued to 100NM.
Which interestingly must be pretty fooking tight, as I tightened the pressure plate bolts to the manual 30nm, not thinking it was tight enough got my normal smaller rachet and tried getting a extra push on it... nope.
Jobs a good one I think, went far too well, ended up shoving a socket with a mate on a bar on the bolt on the crank pully to stop it from turning over. Clutch alignment tool still goes in and out nicely so all is straight.
Next job, gearbox. xD

Nice one. I tend to only bother with the correct torque for things like suspension, rotating bits or anything else that's vital it doesn't come undone like wheel nuts. Other stuff like random bolts just get done up tight.

My elbows are all over the place, that's why I need a torque wrench :wack:
Makes me wonder if I should check my suspension now. But I thread locked everything and cba messing with it again. ¬_¬
