Hello gents, i'm about to order my new clutch, including the spigot bearing. Many of you suggest to change the release bearing as well. It's a cost of an additional 350 euros. Under what conditions should this be replaced?

Had a talk with Miles in MC, he suggested to buy it and sell it if not needed. Is there any evidence that one's bearing should be replaced?

For example, if you hear a boiling noise, then it';s the spigot...what is for the release b?

The rule of thumb is that the release bearing should be replaced every other clutch. If it were me, I would buy it regardless and fit it and the flywheel and the bell housing rear bearing too.

The parts are cheap, its the labour that is expensive.

Myles's advice is sound. The release bearing should be inspected during the strip-down for the clutch change and replaced as required. This is also the same for the flywheel, however I guess either would cause a considerable delay in your case Nikos?

There's a difference between a release bearing that's breaking, and one that's wearing. If it's breaking the PIS point will be inconsistent and often accompanied by 'clanky' gear changes. If it's breaking badly you will drop gears, but if it's wearing then there may be no sign to tell you. The mechanic changing the clutch will inspect it and make a judgement as to whether the release bearing will work correctly for at least as long as the new clutch. If not then he should advise that it's replaced.

Ok, what we need to ask ourselves is how often does the realease bearing fail

I have had one clutch go bang and that was the clutch cover spring fingers or tangs.

Anyone else?

Another one of the more important things to note regarding the release bearing on strip down is .........it may be oozing its grease which is a sure sign that its wearing and prone to failure at some point , worth changing regardless in my view , unless you have clear evidence that it was changed at the last clutch replacement

If the finger springs were failing I'd replace the bearing without question because of the stress on the bearing and the risk of cr@p having gotten in there.

Hmm...I got answers from all the 4200 gurus here... Thank you so much! it seems that i'm buying this as well. The 4200 hasn't had a clutch change yet (still on original since 2003), and with me driving, it won't need one for another 75000 kms... So, i'll get it.. Has anyone a new one in the garage and wishes to get rid of, please get in touch.

I ordered my own bearing from Hills for £285.00 delivered. Comes with seals fitted and ready to go, which was a breather of fresh air said the indy, as the Maserati ones are apparently not ?? He also said that the fail rate of the maserati and ferrari release bearings was alarming, which is excactly what the guy said at Hills, which is why its their most popular item sold. They made the release bearing due to demand as the factory stuff was so sub standard. I think he states this on his website too.

Smoother action means smoother changes or smoother working inside the clutch/flywheel?

Because, i don't need smoother changes..

The way to avoid a nasty failure of the release bearing is to modify it. Will cost less than €50 or free if you know a good welder. See page 2 here http://www.sportsmaserati.co.uk/sho...ible-Bulk-Buy/page2?highlight=release+bearing

REMEMBER TO COOL THE BEA|RING IN OIL whilst welding or you will destroy it.

Mod could be done to an existing bearing without issue.

Yes its a great mod, but we are talking 4200 bearing which is totally different.....I thought I would state this so others don't get confused.

Thanks Matt. I was unsure but was leaning towards the subject matter being 3200. So don't try my fix on a 4200!
