Ford 289/302 and Chevy 305/350/454 balancer pullers work as well on our flywheels. Might get those easier in canada.

Mine recently took a couple of weeks to get off ... I completely destroyed the puller, including pushing the centre out of the puller's metal spacer that locates into the end of the flywheel, it left a metal Polo around the centre threaded section! In the end I felt it was the use of plenty of heat on the collar section of the flywheel that enabled it to let go, I just kept adding more and more pressure each day with my jack handle over the socket wrench. And when it went it went with a bang!

 

When you fit the new flywheel (or refitting the old one) use a little valve lapping paste on the crank taper and rotate the flywheel a few times to help take of any imperfections, obviously clean it up before finally fitting the flywheel properly.

Kept trying with the puller but the bolts just keep twisting as I apply more force. Ordered a different puller today. I'll have to wait until it arrives to try again, but fingers crossed it will work.

It does sound like the threads for the central bolt are too tight - oiled up you should be able to hold the bolt and literally spin the puller body up and down it (off the car obviously).

I managed this by using the puller tool as tight as it will go, then  the using a suitable drift ( a length of thick walled pipe or similar), place the drift thro the starter motor hole against the inside of the flywheel give  the drift a substantial hit with at least a 2 LB hammer,It will fly off so put something soft to catch it.

Received the new flywheel puller in the mail today and went back at it. More of the same, it's as tight as it'll go. The middle bolt on the puller is starting to strip but I've just kept tightening it. Tried lots of heat but it won't give. Is cutting my only other option? Where is the best position to cut without damaging the crank?

[nicklouse]

sounds more like tool abuse.

 

did you lube the main drive thread?

 

tighten and leave. tighten and leave. it can take many repetitions it can take hours,days or even weeks.  

 

they either come off quite quickly or they take time. never needed to add heat but a shock to the drive bolt end can help.

[pakgorgor]

Yes, oiled threads and greased the end of the centre bolt where it contacts the little bit which contacts the crank.

I've tried pounding the end of the bolt with a hammer and have left the puller on with tension for now.

It's not pretty, but it's finally off. A grinder took care of it swiftly! Thanks all for the help.

When putting it all back together, is it necessary to use a new flywheel bolt (the 32mm AF one). Haynes says yes but the question is why? It's not a stretch bolt is it?

[nicklouse]

the lock tab is welded to the bolt.

 

but a good threadlock works as well.

[cal844]

You dont need to change the bolt, I dont unless I dont have enough tab available

[need4speed]

Gotcha. Just had another look and it all makes sense.

[need4speed]

Now I've got my new gearbox and clutch I have question relating to the flywheel. As far as I understand, the pressure plate and flywheel are a balanced pair but I see nothing in the way of markers to say how they align with each other: as in rotation-wise in order to maintain the balance.

[cal844]

Usually the clutch is balanced on the crankshaft as an assembly. Unless it's a fresh build I just try to line the bolt holes and dowels up and go from there.

Hope this helps
