Panigale V4 dry clutch pack

So as I read it the clutch pack thickness is laid out to be 36.5mm thick. This is made up of friction plates, 1.5mm steel plates and a final 2mm plate.

I also read that the clutch pack does wear quite quickly.

On the older 1198 etc slipper clutches I have had, like the v4 a fairly quick job to take it to bits to measure and if required I have maintained the pack height by swapping out a 1.5mm steel for a 2mm steel to attain the pack height again.

So who measures their dry clutch pack height and once there is a total of 0.5mm of overall wear to the friction plates, has or would swap out a 1.5 to a 2mm to get back to the recommended pack height?

Nifty question. So compared to the wet clutch, the dry is for sure more of a pain in the ass from a maintenance perspective. That being said for me (personal opinion) the dry is am much nicer to operate, modulate and the predictability is again for me, excellent. The wet clutch is like a giant flywheel.

To your question and there are some assumptions. Assuming you are measuring your stack with a flat set of plates (you have actually laid the steels on a machined flat surface (steel or stone) and measured the flatness with the appropriate feeler gauge) you have determined that .5mm of friction material is gone, you have inspected the friction plates and determined that the wear is uniform and not excessive on a disc or two, then yes, you can make up the stack height with a .5mm steel and restore the stack spring pressure. I would also inspect the steels for thermal degradation.

Now you do have degraded friction plates so you will obviously have to monitor. There is a nifty tool available that allows you to measure the stack without pulling the plates. It takes a few seconds. Definitely worth having.

On the older 1198 etc stuff I had a top tip from John Hackett regarding measuring the stack height in site rather than pulling them all out.... this used to be 4-5mm height of the last plate below the inner drum....
;-)

where do I get the tool from? any links?

I always had an extra clutch pack, when the clutch slips it’s time to replace,

Yes do do I but I can’t see any reason why it’s not acceptable practice on a v4 to do the same as the previous dry clutch models…

Here’s a thing…
The v4 clutch plates are the same size as the 1198 48 tooth ones
New v4 on right old used 1198 on left..

And I’ve got a few 2mm….for the future

Easy way to do this is get some baseline measurements with a new, correct stack installed and measure the distance between the last plate and the edge of the basket. You can then use this as a reference point using dial calipers to monitor the wear.

So the same principle as the old one….
Currently mine is 5.3 outer drum down to last plate outer..

That’s about as easy as it gets

Yeah… I guess the outer drums vary so can’t compare yours to mine..I’ve got a new plate set I can set my datum to then go back to the current set and see…

Good plan

New plates in ….4.9mm
Change a 1.5 for a 2.0 …4.99
