How To: Barnett dry clutch upgrade

[korey]

In this tutorial I'm going to cover the entire process of upgrading any Ducati with a dry clutch to Barnett components.


Here is everything we are going to be installing. A whole new clutch pack, basket, springs/spring retainers, and pressure plate. They also offer a clutch cover, but I'm not going to be running any cover.


Here is the pressure plate. I got it in red but it is also available in black or gold. The design is a stronger reinforced design, which also helps protect the clutch in the event of a crash. Note the bearing and pin are also included.


Here is a close up of the basket. You can see it has a stainless steel insert that helps to stop grooving from the tabs on the clutch plates. It is also available in the same colors as the pressure plates.


Another picture of the basket.


The springs are black powercoated gloss black for a great, durable look. The bolts are stainless so they wont rust, and the caps are also available in an assortment of colors.


The clutch includes everything you need.


Now to begin the install. Here is the tired old looking setup that was on the bike.


First, remove the clutch cover from the bike.

First, remove the clutch cover from the bike.


Now start removing the springs.


Remove all of them.


Remove the old pressure plate.


Now pull out all of the old clutch discs. The easiest way to do this is with a small flathead screwdriver on each side, pulling outwards evenly using the tabs.


Here you can see the friction discs had no material left, this clutch is done.


Remove the shaft that connects to the slave cylinder. It pulls out.


No shaft.

The hub can be removed without using the tool if you want. Just put the bike into top gear and have someone press down on the rear brake. I used an impact.


Remove the bolt. There is also a washer behind it.


Pull out the hub.


Now remove the bolts holding in the basket. If you use an impact you don't need the tool.


You can see the grooving on the old basket, this is only after 5000 miles.


Now install the Barnett basket. The bolts need to be red-loctited and torqued in a criss cross pattern. Torque values may vary so look up what the factory says for your application. You will need a tool to hold the basket while you torque the bolts. You can buy one or make one, I made one however it was somewhat crude looking so no pictures of it. Here is more info on making them.

Put the hub back in place.


Torque the bolt, forgetting about the washer that has to be behind it. Once again use the tool to hold it in place while you torque it, torque values may vary.

Here is how the clutch has to go. Refer to the diagram that came inside the clutch bag itself. Also be sure to wipe off the oil from the metal plates.


The new friction plates have much more material than the old ones we removed. They are also an improved material and design.


Now time to put everything in the bike. Don't even try to do it all in one shot, it will never work. Do them one by one making sure to keep them in order.


Put the rod back in place.


Now time to put the pressure plate on.


As you can see there is a mark on one of the tubes the springs slide into.


It must be aligned with this post on the hub that is also marked.


The bearing and pin are preinstalled.

[korey]

Slide it on.


Now install the springs and caps in a criss cross order.


All of them installed. Tighten until the bolt is snug. Everything is done, you can now install a cover of your choice. I am running coverless.


Here you can see how tight the plates fit with the basket.



After riding the bike for a little bit the new setup is great! The clutch feels great and holds all the torque like nothing, also thanks to those improved springs. The basket is great and the clutch is MUCH quieter now than it was before, however it still retains the Ducati dry clutch sound. And the new pressure plate just looks amazing! All in all something I would recommend to anyone with a dry clutch Ducati! They also sell an upgraded clutch pack for wet clutch bikes. More info can be found by clicking the logo below.

Great writeup! Looks very straight-forward!

Did you have any problem with the stack height? I used a different basket and had trouble with the stack height on mine, hard to find neutral. I have it sorted out now. Nice write up!

Thanks guys

No I didn't have any problems with it, and neutral is still just as easy to find as before. However if I recall correctly I did see one or two people mentioning having problems with stock baskets I think? Personally I'd recommend everyone to go with their basket as well, mainly because of the stainless steel inserts on them that really should make the basket last a lot longer and resist grooving. What wound up causing your problem?

I went with a MPL hardened basket, pressure plate and 30mm slave. The problem is most likely because the slave doesn't have sufficient travel. I changed a few steel plates around from the old pack to get the proper stack height and all is well.
