I've had one laying around waiting to be fitted . I have 1 question - What grade/type of grease should I use on the ramps/balls and the spider spring ? Do any of you have any other advice before fitting ? Cheers .
Thanks for prompt reply! I have already downloaded and printed the tech sheet , hence the question about grease . Presumably high temperature stuff ? Should I get a new spring for the spider just in case ?
I never used high temperature grease. It was only used on the ramps and ball bearings surfaces and I haven't encountered any issues. You could use high temperature grease I suppose. The Ducati workshop manual for the 1098R slipper, again specifies "Grease" without being specific. Spider springs are expensive. If the one you have is fine, just use that.
Molykote dry coat molybdenum sulphide spray as used by my preferred workshop or generic "fifth wheel grease" which is similar to the stuff Ducati recommends. Whatever you end up using, use it sparely as you don't want the grease melting and running into the clutch. Regular cleaning and routine maintenance are key to operation and a long trouble free life. If your spider spring has not been under compression all the time it has been stored probably not but if you do decide to change it, be prepared to pay £60. Andy
Actually, the 1098R manual is specific. Thumbing through the manual, this is what is specified for the slipper ramps. The grease I used on my clutches falls within this criteria.
Fitted the jhp slipper to my 9s (same clutch as Dp) very easy install just get the stack height correct, Ive since installed a set of barrnet friction and steels, All good
I also note that 1 of the steel clutch plates should be dished , is that correct ? By how much ? Putting a steel rule across them would suggest that all 8 are flat ! I don't know why but .. Would the std Ducati plate suffice ?
Dry slipper clutches are notorious for juddering has you let the clutch out from stationary and the 1.5mm steel dished plate is added to illuminate or at least alleviate this. I currently run 2 x 1.5mm dished plates in the middle of the pack in a dished, friction, steel, friction, dished sequence which works for me. The set up whilst not complicated can take a little playing to get right, it is just a matter of trial and error if it is not right first time. Nominal pack height is 36.5 but can often work better slightly smaller, say with a 1.5mm steel instead of a 2mm steel. I have also found finishing the pack with 2 steels often helps. Andy
I run 2 dished plates on the Streetfighter as I couldn't stop the screech when pulling away with only one dished plate.
I have reverted to the earlier 748R all steel, 3 ramp (no ball) slipper clutch in the 853 because I have found a formula that works for me. I spent far too much time faffing around with the 6 ramp and ball slipper and never could not find a sweet spot and I was shocked at just how quickly the tangs on the aluminium friction plates wore out in comparison to the steel ones. Just rebuilding the all steel slipper from my spare 748RS engine to put into the 1098R to see if it makes a difference. Andy
Hi RickyX , None of the steel plates that came with the S/H clutch are dotted/marked to signify they are dished , they are all 2mm thick as well . The clutch currently fitted to the bike definitely has a dished 1.5 mm steel plate . Can these be purchased separately ?
Not from Ducati any more but EVR do. If you ring Craig on 01962877998 (option 1) at Moto Rapido, he does usually stock them and the postage is reasonable. Andy
As far as I'm aware, your Ducati dealer will be able to source them for you. I've bought 4 in the last couple of years. The part number you want is 19010243A. They are about £7 each iirc.
Hi , I had already emailed the efficient Moto Rapido and can confirm they do stock the dished plates @ £9.50 each . Thanks for your help guys . Clutch plate pack height to aim for is 36 mm ?
