Default Flywheel Bearing?

I'm having the clutch and gearbox mounting replaced on my Navara (D40, 2009, 4x4, 2.5 diesel, 4 dr).

the chap says he's worried about the "flywheel bearing" as it may be faulty. He says that it is an integral part of the flywheel and cannot be replaced separately....is this the case?

P.S. - the guy is not a Nissan specialist, more just a journeyman mechanic.

BTW - it doesn't have a dual mass clutch.

If he is referring to the pilot bushing, yes it can be replaced. It is a small roller bearing or bronze bush that sits in the back of the crank and is where the input shaft of the gearbox goes into.

to get it out use grease or a non messy method is wet bread. shove into the hole and use a socket extension or something of similar size as the input shaft to push into the hole to get the bearing out.

As Tony mentioned above, they are/were also known as a spigot bush.
Curious to know if he is possibly referring to the clutch throw out bearing, both can squeal when pushing the clutch pedal in and out. either way, the box has to come out!

I'd be interested in what he's referring to as well.


The flywheel is bolted (quite firmly) to the crankshaft and has NO bearing other than the crankshaft's bearing.


There's a throw-out bearing that presses against the pressure plate - sometimes called a "thrust bearing" - and I can't think of anything else that might be an issue in a clutch change.

Never heard of a "flywheel bearing"?

As others have said, there are no bearings in the flywheel. It's just a big round lump of metal bolted on to the crankshaft.

The spigot bush and thrust bearing are usually supplied with the clutch kit (some also have a plastic centring tool). Changing them with the clutch wouldn't normally need mentioning, it's normal procedure.
