Slipper clutch fitment
 

Hi,

I am planning to fit a new Bucci slipper clutch which was brought in from Italy. Does anyone have a copy of fitting instructions in english as my italian is a bit poor. I have the haynes manual and the slipper does not seem too different to standard to fit but not sure if I need to grease the ball and ramp assembly. Can anyone help.

Cheers Andy

Have you got the proper tool for removing the centre hub?

As far as greasing the bearings, there is a high temp grease available,....but i have used a minute amount of copperslip in the past.

If you get as far as building.......... you need to build in the right sequence includind setting the dished plates the right way round, finishing with the height of the stack set correctly!

Andy You have email regarding the holding tool

What plates you using Andy748?

Alloy plates as from what I have read on the message board this seems to be the best choice.

Good. You don't want to eat that lovely basket up bu smashing away at it with steel plates.

If you strip the clutch right out as per the manual instructions.

1 Pull out the top hat spacer and slide it off the crank.

2 Remove the rubber "O" ring from inside the top hat spacer and put it in the new spacer.

3 Apply a smear of crease to the new spacer and slide it gentley on to the crank and push it fully home.

4 Slide the dished washer, dome face towards you onto the crank and push it against the spacer.

5 Fit the new basket,

6 Take the outer hub and smear a bit of high temperature grease onto each ramp. Then put one of the ball bearings onto each ramp. The grease will hold them in place. Place the center hub over the top so that the pins lin up with the holes and slide it into place.

7 Push the whole assembly on to the crank and push it home.

8 Place the spider spring over the crank allowing the arms to rest in the machined out places for them. You shoud have a stepped washer. Place this over the crank up against the spider spring. The stepped side should fit the spider spring like a glove. Fit the center nut and tighten it up. You will need a clutch holding tool for this.

Start first with a friction plate, ( not has the manual )
Then a steel pressure plate
Friction plate
convex pressure plate with dot towards you.
Friction
Pressure, so on and so on.

The final convex plate should be placed one from last with the dot
facing away from you.
Now the final friction plate
and now the final pressure plate. Never finish with a friction plate.

You should now measure the distance from the face of the last pressure plate to the face of the center hub. It should read between 3.5 and 4.5 mm.

Any diverence should be taken upby swopping the pressure plates over for thiner / thicker ones.

Its just a question now of placing the final pressure plate and fitting the springs and washers, etc.

Hope this helps.

Good post Jon, quality!!

Thanks again Tp. There is not too much difference between a std and slipper other than starting with a friction plate and making sure the correct Sequence of spacers, washers, etc, is kept too.

Jon,

Many thanks for that - just 1 additional question: I only got 1 convex plate in the new pack (for 748 bip), do I use the one from the old stack to build as you stated?

Mikey,

Cheers for the tool details - will try to contact them.

Yes Mike. Use the same torch settings stated in the manual as well.

One more tip. After you have fitted the ball bearings and placed the center part of the hub on. Turn the hub clockwise to check that everything is running smoothly

Jon,

Thanks again for the quick reply.
