355 Need a 355 Flywheel & clutch housing

What broke? What was causing your rattling noise?

 

Let's not confuse the flywheel and The voirh dampener. Billet flywheels are available from superformance. Voith is available used. Pumpkin new and used, I'd go used.

Thanks! Hopefully I've caught mine in time. One day it wasn't there, one day it was. How long did you have the noise?

Just wondering if I should get my car towed to my mechanic, 10 miles away.

 

Video of voith repack.

As far as the pumpkin unless the bearing would not seat anymore I would not replace the pumpkin for that minor scraping. That grease flung out you need to inspect the voith for cracks, only way that much grease comes out is if the case is damaged. The voith bolts to the flywheel.

The video will make it clear.

 

I do have a spare flywheel it would need to be surfaced and mostly likely have the grease repacked.

It came out of a F1 trans I needed parts from. I sold it as well as the cover but I do have the flywheel.

 

Glad you were able to source the problem. Sorry it was not as simple as hoped.

Have you look into a machine shop that can weld up the area and then machine it back to spec

I have done that with other parts (head, intake and mounts) that had cracks and was way cheaper all where aluminum parts

I have just bought a new billet flywheel from Hill Engineering. Very good price compared to brand new factory units.
The pictures show the old and the new unit.

Which part is causing the damage? The flywheel inner shown in the photos in the post above or the part with teeth for the starter... or none of the above?

The voith damper rubbed the housing. Probably the rivets which are in fine shape. It also threw grease which is not related to the voith rubbing. Not sure why the billet flywheel needs replacing, or the voith unless it's cracked from reusing clutch bolts. The pumpkin is hit or miss the voith rests on the bearing inner race not the housing. I'd be shocked it any of it needed to be replaced except the voi g which needs to be I inspected to grease escapment.

Looks nice. Probably wouldn't be of interest to most but did you happen to compare weights?

 

I did not put it on the scales but it was very noticeably lighter and very well made.
Notice the balance holes on the standard flywheel, then notice how there are none on the new flywheel. So clearly machined to tight tolerances.

 

Actual Flywheel plates wear over time, you can machine them but then they warp or wear sooner and gaps and tolerance can get thrown off, alternatively you replace them. The billet flywheel disk is a consumable part, like clutch plates. The Voith damper that bolts to the billet disk is rebuildable.

 

The part that touches the clutch is called the flywheel. The other parts your talking about is the damper. As said they can be rebuilt.
I replaced because it was very worn.
Just look at the face of the old flywheel in the pictures compared to the new unit.

 

Where did you get your parts? I’m looking for the o-rings (seals) to rebuild my damper. Thanks!

 

They're no individual parts for the o-rings that are inside the damper. You have to take them measure them and buy them online from an o-ring supplier . For the damper there are no seals just the kluber grease , o-rings around the bolts and the large o-ring for the two cases. Beyond that there are two bearings you can replace if they need replacing.
