DIY Dual Mass Flywheel

[jesus_man]

I suppose I need to tackle this over the coming months before it explodes and takes out more stuff. Not a project I am looking forward to, but before I decide to DIY, are there many special tools that would merit looking into a local shop to have it done? Anyone come across any good write-ups? I have found youtube videos, but have not watched them yet.

I don't remember having to use anything special when I did mine. I think 90% was socket wrenches. You'll need a way to hold and manage the transmission. So ratchet straps, jacks, blocks of wood, etc if doing it in your driveway. Other then that it was pretty straightforward

I agree that other than a transmission jack and the usual triple square sockets, my first one was out in less than 3 hours. It is nice to have the tool to lock the flywheel when you torque the bolts. I didn't even lose any transmission fluid. The hardest moment is getting it back on and lined up so it just 'falls' back in place. Do NOT use bolts to tighten the bell housing. I did use a big wrench to turn the crank a little bit so that everything lined up. Oh, the transmission is HEAVY!!

Any tricks to removing the pilot bushing?

Yes, and what other things should I replace while I'm in there? New DMF bolts, etc? This is for a DSG if that makes a difference.

I rented a bearing puller from the auto parts store as I did not have one the worked.

I read a post somewhere that said you could take a piece of bread and use a dowel or rod that was about the same size as the hole and mash the bread into the hole and keep hitting the rod and it would slowly build up pressure as you mashed the bread into the hole. This eventually pushed the bushing out.
As silly as this sounds I will be trying it just to say I did.

Instead of bread, what I've read is packing it with grease then knocking the dowel/rod in there. The "hydraulic" pressure from that causes anything that can possibly move (the friction-fit bearing) to indeed move.

And then there's the cases where bread/grease/dowel don't work, and you need the bearing puller tool anyway.

 

[Tuheeden]

Yep, I tried the grease trick and still needed a puller!

 

[jesus_man]

Depends on how tight the tolerance is to the dowel, and how full the cavity is with grease. I've seen it work.

Pay a shop if you can! Had mine done here in Sac for $1800. Parts and labor. Pilot bearing was toast too.
