Clutch plates
 
1 Attachment(s)
It doesn't seem like people buy a Ducati to ride daily but my question is about how many miles are the clutch plates good for before they need replaced with regular riding not racing the bike.Attachment 93840

I got 10k miles out of my original plates & basket - mainly moderate road miles.

When you replace the plates it is a must to replace the basket or you just do it for good practice.

You only need to replace the basket when the tolerance between the friction plate teeth and basket becomes too much. OR of your switching from a 12tooth to 48tooth clutch pack. I don't know off hand what the measurement between the basket and friction plates is offhand

Rust doesnt matter on the friction

For the pressure ones (metal) I deglaze/derust them lightly on a wire wheel then rub them on a 120 emery mat (with rubber underneath) north/ south then east/west to etch a small pattern on them,then reutilise them.

If you start to feel some slippage get some scotch brite heavy duty (green pads) and clean up the friction and steel plates works wonders brings em back to life like you wouldn't believe

Ok Bdar that is the project for this weekend. I already have the pads now I will clean them and hope for the best. I've read on a different post lithium grease works wonders after they are cleaned. Have you heard anything of the sort?

Around 10k
my clutch basket got so noisy it sounded like I had a internal engine knock . The teeth on the plates and the basket were worn , but it felt fine and didn't slip at all.

That is right...even new plates come with a thin layer of of grease.

If you have to replace the clutch plates or plates/basket, what would they cost? If you had to have the dealer do it, what would it cost? Just asking because I am looking at purchasing a bike with almost 9k mi's. I'll have to look at the records to see if they've been replaced or not.

I highly recommend doing it yourself; too easy to justify paying someone else to do it IMO. As an example, Motowheels has basket/clutch packages around $375. Just plates will be cheaper.

I spray the linings white lithium spray lube (with no friction modifiers), wipe off excess and install. It works wonders to eliminate clutch chatter and grabbing and no, the clutch does not slip.

Linings? I'm sorry I'm not understanding.

The friction material on brake pads and clutches is sometimes referred to as lining

The standard test for detecting worn-out clutch plate friction material is to watch for slippage when accelerating in top gear. Some people are just harder on clutches than others, so service mileage will vary over a wide range.

You can often stop slippage by maintaining the force pushing the plates together. The idea here is to maintain the 38 mm new stack height as the friction material wears off and reduces the thickness of each plate. The higher the stack height, the more the springs are shortened/compressed, and the greater the force pushing the plates together. The clutch slips when there's not enough force supplied by the springs or the friction material is worn completely off.

The service limit on 3 mm friction plates is 2.8 mm. For 2.5 mm plates the service limit is 2.3 mm.

The plain metal plates come in stock 2.5 mm or 3 mm thicknesses. When the overall plate stack height wears 0.5 mm, replace one 2.5 mm flat plate with a 3 mm one. At 1 mm stack height wear, repeat for a second flat plate. At 1.4 mm - 1.6 mm wear, replace all the friction plates. Allowable friction plate wear is 0.2 mm (each).

Ducati considers both the plates and clutch basket to be wear items. By the time you need to replace the worn-out clutch plates the basket has been notched from the impact loads of the plates. Ducati specifies the allowable gap between the plates and basket as a quite small 0.6 mm, effectively saying to replace the basket and plates together.

Also check the pressure plate throwout bearing and pushrod for smooth rotation.
