Title: Tips for removing crank bolts?
Post by: emery1990 on 05 February 2012, 12:44
Think they are called crank bolts. the 6 bolts that hold the clutch plate on. Well I started on my car again after 5 weeks off, first minute it slipped and took a chunk out of my thumb, It just doesn't want to budge at all. I'm hold the other side with one hand and using my foot to try and undo the bolt, but nothing! Is there something that holds the crank still while I try and undo the bolts?

Use an old piece of timber or metal with a hole each end. Put a large hole one end and secure it into one of the gearbox mounting holes, and a smaller hole the other end and thread a long bolt through it and through one of the holes in the pressure plate, and stick a nut on the end. It will bend, but it shouldn't snap so should be sufficient to hold it still.  :smiley:

Ok that sounds like a good idea! Cheers.  :smiley:

spanner works to wedge it     put a bolt through the ring end then wedge it against the pressure plate

You may need to warm them up with a blow torch to melt any thread lock. Mine were all locked on. 5 came off easy when warm, 1 got ground off with my grinder :shocked: then sloted the stub and used a screw driver on that once the plate was off. Theres some trick to lock the crank. Broke VW gearbox chap I think it was.

Broke VW used a spanner, like Danny suggested.

cheers, ended up using the spanner and blowtorch mehtod, came out so easy then! When putting it back on the pressure plate has to centralised, haynes say either a vw tool or a homemade bit of wood and dale. Any other tips for putting it back in central, got a lightened freewheel to go back onto it :cool:

I didn't have a tool either. I just used a vernier caliper on the 3 or 4 corner parts that are closest between the clutch plate and the flywheel. Took a while to get it perfect, as had to keep doing up, then undoing the bolts to make sure it was central, but worked a treat!  :smiley:

you'd be suprised how close you can get things by eye and feel.   the trick is to just tighten the bolts holding the pressure plate on so you can nudge it about before tightening it up.   

as long as you can get the main shaft to locate in the friction disk and on the box on the dowles it's fine,   there s a littel bit of give in the assembly and when you first operate the clutch it'll settel itself where it wants to be.     the cluch centering tools arn't that accurate anyway.

on an 020 you can eye them up easly   the center of plate that the push rod hits makes a good target to sight against

i do em with a small piece of steel rod and use insulation tape to get the right diameter on the rod in the right places in relation to the plate and crankshaft but make sure they are a nice tight fit.works everytime.

Been waiting for this weekend for ages! When fitting the flywheel, do I have to get the engine to tdc then fit the flywheels mark at tdc too? Or do I just put the flywheel on? haynes doesnt say anything about this. Its a brand new clutch and a new lightened flywheel.

Just read that the flywheel can only go on one way? Can you see the push rod, I didnt see when taking clutch assembly off my 9a, neither did I see it taking it off my abf. But it keeps on going on about a push rod.

Got the engine in, round the back the clutch assembly is on show, is this right? I'm using an 020 gearbox with abf. How many bolts actually holds the gearbox to the engine, so far I have only out in the top two, but on the 9a, I removed one next to the drivetrain, but this is no longer there on the abf. My starter motor bolts are to small for the abf, so need to get some bigger bolts. They are the problems i've got, so hopefully easily sorted!

two bolts through the gearbox into the engine at the top,   one bolt through the engine into the gearbox lo down at the back of the engine.

then the starter bolts carry the frount mount bracket,  run through the starter, box, engine and into the bracket.

should all fit without problems tbh

Ok sweet, I was being thick about the starter bolts! Theres no problem. Is that normal for the clutch assembly to be on show then?

Ive done it on a golf but theres normally a thin metal plate between the engine and gearbox that hides everything

hmmmm, ill get pic up later, cant see it being right with metal at 7000rpm on show

I assume you mean at the bottom. There should be as said, a thin half moon shaped metal cover that sits over the top of it. Lots get lost over time though, but if you cant get hold of one, any thin aluminium plate cut to size will suffice. Its only held on by 2 bolts.  :smiley:

one of my cars had this missing makes driveing through a flood suboptimal aswell.

  it makes a rather diffrent and unusual sound when a load of water gets in the bellhouseing and starts getting thrashed about by the flywheel  this must also disapear quite a bit of power as well   so end up needing more revs so it makes more noise.   

first few times you'll wonder whats just broken
