Hi guys, I'm planning to install a 48t yoyodyne slipper on my 1098s and my question is when I torque down the clutch center nut i was told to use an impact wrench ( which is what the race mechanics do), well my impact wrench (sears craftsmen) has 3 torque settings but has no specfic torque ratings for these 3 settings according to the manual, the max torque of this wrench is 550 ft lbs.And when I use the 2nd setting, it doesn't seem tight enough, so am kind of hesitant of using the max torque setting in fear of stripping the threads. If I opt to use a torque wrench, then I would have to buy the 48t clutch basket tool and then I will have buy another torque wrench since the torque is 184 ft lbs. what has anyone else done on this issue and any suggestions would be helpful, thanks, bill

Take it to a dealer....or buy the tools.

I went with the second option.

I wouldn't do it with an impact gun as you have no idea what setting you are tightening it to.

Probably not the answer you wanted to hear.

Buy the tools man. Try contacting Phil 1098 on this forum I know he makes really nice clutch holding tools(as I use it) and I think he now makes one for the 48 tooth basket.

And the 1098 calls for 250NM on the clutch Min 236NM max 264NM, I dont know what the ftlb conversion is but you may have it right.

Its worth the money in the long run as you will be removing and inspecting etc...

thanks for the replies, I contacted TSS directly (they make the clutch for yoyodyne), they are based in the czech republic and the tech there replied to my emails within just hours, so good customer service, anyways he said a universal clutch holder should work to hold the drum in place so I'll see, if not I'll check out phill's stuff. Just a note to anyone else interested in this clutch, TSS now makes a 1098 specific model for the 1098 now (model #10951), obviously it comes with the larger nut and washer but the main difference is the diffterent pressure plate because of the different size clutch springs that the 1098 uses. To make my clutch work (model #10911), the tech instructed to use 999 clutch springs, so I ordered some from motowheels, will probably install this coming weekend, let you know how everything went.bill

What do you mean by standard clutch holding tool?

If you mean the vise grips looking one from motion pro etc...DO NOT USE THIS ON YOUR DUCATI HUB!!!!!!!

YOU WILL BUST THE HUB FINS because of the extra torque, the motion pro tool works fine for others but not the duc dry clutch.

I have the tool for my 675 slipper and wouldn't dare using it on my duc.

thanks for the reply, well the tech from tss said I could use this troublefree, (he actually quoted a yamaha or honda universal tool), I happen to have a 02 r1 track bike and in the manual the tool is the exact one that motion pro sells. but I'll take your advice and shoot for something else. are there any suggestions as to what tool will work with the yoyodyne (tss)clutch?

It's 185lb.ft of torque. I used a big torque wrench on mine while developing and testing the clutch hub tool. Your eyes will get big just before the torque wrench clicks...........it's a LOT.

You will find the old saying about having the right tools to do the job right to the extreme on this one.

I did my STM two weeks ago and man was I happy to have the right tools.

Phil when will my promotional checks start coming?
