Barnett Clutch Installed

I just finished installing the Barnett clutch pack. This replaces the second clutch after about 29K miles. The first one crapped out at 11K and was replaced under the factory warranty. The extended warranty won't touch anything to do with the clutch and I was unwilling to spend $1500 just for the replacement parts from the fatherland.

The clutch didn't slip, but had rather severe juddering as did the original when it failed. The friction pads on the first disc, where it rides on the aluminum hub, were gone. It was aluminum on aluminum. Only very slight wear on the hub surface. There were no undulations hammered into the hub splines by the drive plates but there was slight hammering on the basket. I chose not to dress it up as it was fairly minor,

Disassembly was straightforward with the factory clutch holding tool. The center nut is torqued to 148 ft. lbs. so the proper holding tool was almost a necessity. Assembly is pretty easy but you have to be careful to get the friction discs in correctly. There is one narrow slot and a narrow ear on the disc but they are not symmetrical. so you have to make sure each one is flipped the proper way to slide into the basket. The small ear is marked with red on each friction plate. Torqueing the center nut to 148 ft. lbs. would seem very challenging without the holding tool so I was glad I got it. The six 5mm bolts that hold the spring were torqued to 20 Nm. I replaced the one-shot aluminum cover bolts with reusable titanium bolts tightened to 80 in. lbs.

The test ride went well with no juddering or other problems. The whole job could be done in about an hour or so. I took a bit longer but it would go much quicker the next time.

I don't have any problems so far, but others have done this with great results. Did you happen to take pics along the way? Would make a nice DIY post

No pics, sorry. One further observation though, it is evident that not enough oil gets to the clutch. When the first replacement clutch was installed by the dealer, they installed the updated oil nozzle. Apparently it still isn't enough.

Where did you acquire the clutch parts and Ti bolts? Thanks for the good tips.

Ebay for both. The Ti bolts are Torx head made for bicycles. They are more expensive than the stock BMW aluminum bolts, but I will never have to replace them just because I removed them. (There is no reason you couldn't use steel bolts.) One more comment, some will use an air impact wrench on the center nut but I don't like the idea of hammering on the transmission so I loosen it by hand.

Good stuff here. Wish you had some pics, though. I will be doing this as well shortly. Your description of your clutch failure Is a match to my symptoms right now. The stock clutch made it to 20k. I like the fact it is practically in my lap for working on, though! Thanks for the info!

I have the same question for my '06 K1200S, fwiw, so I'm bumping again. Some people have reported drilling out the hole in the end of the flat-on-one-side end of the nozzle, but no one has posted either a how-to for that home remedy, or an "updated oil nozzle" we can just buy and install ourselves.
