Installing motowheels slipper clutch...HELP!
We're currently installing our MotoWheels slipper clutches:
Linky
We took one of them appart from how it came from Motowheels, started installing and left the other one intact so we could tell the order of everything when putting the first one back together.
Well...we're confused.
You put the basket in, and put all those bolts in, then you put the hub in, then put the plates in, then there's this spider spring. It has 6 legs. It goes in, then there's this washer that fits down in the hole that goes around the push rod. Then there's the nut that holds all that together...
Then what?
The way it all came from Motowheels, the next thing is this steel curved washer then this thicker standoff....but how are you supposed to keep the washer in place? It drops down and hangs off of the pushrod and there's no way to hold it in place, same with the thicker standoff washer.
I put a bit of grease on the steel washer and placed it against the nut to hold it in place, then put everything together, put the 6 springs in and tightened everything down.
When I pull the clutch, it doesn't pull even, the pressure plate doesn't pull in evenly and I'm sure that's not right!
Anyone have any ideas?
Anyone?

This is how things are installed now:

Here's the back side of the pressure plate:

And here's the steel washer thing:

And here's the thicker standoff washer I mentioned:

I've taken the last two images out of the stack and things seem to work fine. With them it it slipped like mad (20 mph, romp on it, hit 6k, going 23mph now). Now it doesn't, but it also doesn't seem like it does the job of a slipper clutch either
Does this seem right?
We also have 7 friction plates installed and 9 steel plates.
That left us with a friction and a steel plate left over from the kit. They wouldn't all fit in there. What we have in there now is the same numbers as stock....does that make sense?

I've found this link:
http://www.mad-ducati.com/Technical/BucciSlipperClutch/BucciSlipper.html
On page 2, it shows that when you remove the stock basket, you will have the group 'F' come with it. However, on both of our bikes, we didn't have all of group F. We only had the first nut on the left and the 'F' piece that is shown below the plates on that same page.
If you look at page 1 (exploded view of the aftermarket clutch), it shows parts 16, 17, and 18 going in BEHIND the basket. These LOOK to be the parts that we can't figure out where to place. However, they show part 18 to be substantially smaller than what we have that came in the kits.
I have taken out the clutch plates and the clutch hub and just have the basket bolted in. The input shaft looks like the following:

To us, it looks like the spacer is actually mounted from behind the bearing (with a possible lip holding it in place from behind the bearing?). It looks like it would require pulling that bearing out to remove that spacer. Is that where this piece goes?

The second pic? The second pic is the pressure plate??blade625CT said:
Or are you saying the last pic?
If so, when we place the 'flange' (the part that holds the bearings and has the studs on it) on the input shaft, and then place that spacer ontop of it, we have no threads sticking out to put the nut on.
We only have one dished washer it looks like this:
??????
As it is right now, it's not backing against the 8 basket bolts because the spacer seen in this pic is spacing it out.
I have looked at the back of the hub/drum and there are no marks what so ever on the back side of it from the 8 basket bolts. The only mark is from that spacer in the above pic.
so then the plate order is COMPLETELY different from stock? The plate order in the desmotimes book is only good for stock (non-slipper) clutches? Can you tell me how the plates should go in then? Because if I do friction first it's as follows:
1) friction
steel
2) friction
steel
3) friction
steel
4) friction
steel
5) friction
steel
6) friction
steel
7) friction
steel
8) friction
steel
steel
steel
thanks!

I'm looking at this image:

And realizing that the MotoWheels slipper clutch kit looks IDENTICAL to the STM kit. There's two differences. We only got one 10 and didn't even get a 9.
if you look at this image:

It appears as if 8 and 10 go in place of the spacer that I took a picture of here:

But to do that, I'd have to pull the bearing that surrounds that washer out...that doens't seem right!?
grrrr.....:crazy:

why would you respond to this post if you have nothing of value to add?thisnjducquacks said:
fwiw: we're a coupe who have installed two superchargers on our truck over the years, not having any instructions either.
And, we've installed a world class, world finals winning carPC and sound quality system in my car....that didn't come with instructions either...
Do you have a manual that tells you how to whine?

no mechanical know how?
how about a degree in mechanical and manufacturing engineering technologies from one of the top engineering schools in the nation?
how about working for race teams myself? (not just mearly working for a mechanic, probably just handed the guy the tools he asked for....heh)
The simple fact of the matter is that installing the slipper clutch without removing the spacer and replacing it with the two pieces in question, did no damage whatsoever. It also didn't make a difference when we installed the two pieces that were in question. This was the only area where we were truely stumped.
Having mechanical know how includes knowing when to ask questions. Having mechanical know how includes being willing to try things on your own, and not forking over hundreds of dollars to someone else on something as simple as a clutch install simply because you don't want to do it or don't have the nuts enough to even attempt it.
I'd appreciate your not coming in here and trying to exert some superiority over someone you know absolutely nothing about, because quite honnestly, it shows your age.
On another note, thanks to everyone who actually came in here with some insight. Especially blade625CT. Your last post was the one that we needed.
Even without pulling that piece, when we installed everything the first time and left the two pieces in question out, it still did it's job just fine. We pulled that spacer and installed the two pieces and everything works just fine, the same as if we hadn't of removed that spacer infact.
I do have a concern about placing a friction plate against the metal ring that's around the slipper portion. Those flat topped screws that are recessed into the ring are NOT 100% flat. We're concerned that putting a friction plate against that will eat up the friction material in a heart beat. We just want to check on that.
BTW: I've hosted pics of the process here:

I really appreciate your post 2DucJ. I wonder why MotoWheels doesn't send out that exploded view with these kits? It's something I would consider manditory when shipping a product like this. It sure would save on the Advil on their end from having to answer a bunch of questions, etc.
