    Default Removing/Installing clutch basket

    I suck at tutorials so be patient. I have trouble uploading more than 2 pics at a time so it will be broken down into several replies. I'm also going to use some of these pics to show clutch replacement. Basket removal is no big deal, it took me maybe 30 minutes (counting smokebreaks too) to do the work and take pics too. You need to start with a clean place to put your parts and keep them in the order they were removed. The only special tool you will need is something to hold the inner hub while removing nut. I show you how to do it with an impact which I highly recommend. It makes the job ALOT easier. You will need 10mm socket (1/4" drive) and 30mm socket (1/2" drive).
    Either drain the oil or lean bike on it's left side (I've had success leaning it against wall in shop). Remove the cover and this is what it looks like. Next, remove 5 bolts (10mm socket) and remove clutch springs. Clutch cover turned upside down makes a good holder for the bolts/springs.

    Next pull the pressure plate off. A couple of plates/fibers will usually stick to it, no big deal.

    You can buy/rent a special tool that holds the inner hub while you use a breaker bar to remove this nut. I always use an impact w/30mm socket to remove it. The inner hub will spin, so I stuff shop rags between inner hub and basket. Stuff half the rag in there and use other half to protect your hand as you hold one of the fingers on the hub. Be VERY careful as the edges of the basket and inner hub are sharp and can cut the hell out of you if not careful (don't ask me how I know). Now zap that sucker off.

    Remove the nut and washer. Note one side of the washer has the word "OUT" stamped on it. That will be important when installing everything. Now you can pull the inner hub out. (plates/fibers will come out with it)

    Notice the center of the basket. It has a sleeve over the tranny shaft and needle bearings over that. Notice the sleeve, there are two notches 180 degrees apart. With needle nose pliers grab a notch and pull on the sleeve while wiggling/rotating the basket. You may have to alternate between the two notches to get sleeve to budge. Just be patient and keep wiggling it, it'll come out.

    With the sleeve out, basket will slide out with ease. This is what it looks like behind basket. Gearshift shaft/drum assy. to your left and oil pump to your lower right.

    Okay, after you've done whatever repair you had to do, time to put it back in. Slip basket over shaft. Push it up in there and engage teeth of basket gear with teeth on crank. Next while trying to center basket over shaft, insert sleeve into basket. This is trickier than it looks and may take several tries so don't get discouraged. I've had it go right in and I've wasted 5 minutes trying to do it.

    With both hands, grab basket and rotate it back and forth to make sure it engaged teeth on crank. Next take a medium sized screwdriver and insert it through hole in oil pump sprocket. While pushing in on basket, rotate sprocket with screwdriver. The back of the basket has holes that engage drive sprocket for oil pump. What you're trying to do is engage basket with the drive sprocket. You will know it's right when basket goes in and seats and you can no longer rotate oil pump sprocket. Double check this to make sure it's locked in good and tight.

    Next install big flat washer, doesn't matter which way it is turned. Then install hub, it locks in with splines on shaft.

    Remember the washer with "OUT" stamped on it? Install it with OUT facing...you guessed it..out (facing you). Next install nut and finger tighten it.

    Next you're going to use shoprag trick and impact to tighten the nut. Purists may jump in and bitch cause I'm not torquing it to spec, but I have NEVER had a problem with using the impact.

    Next install pressure plate and then install springs and bolts. The bolts are under considerable pressure (especially with Barnett springs which I HIGHLY recommend) so just get them started with fingers. Finish tightening them with ratchet. Be VERY careful tightening these bolts. The bolts are soft and the fingers of inner hub are pretty fragile. Use a 1/4" ratchet and just snug them. They are under pressure and aren't going anywhere.

    Barnett springs are slightly larger than stockers and can ride against the pressure plate if not lined up correctly. Squeeze the spring with finger and thumb to line them up with the washer before tightening them all the way.

    Okay cover is ready to be put back on. Clutch lever on cover only goes one way. It's pointing almost directly at the engine. Hope this was useful to someone, if you have any questions, just ask. I'm also going to do clutch replacement but it's almost midnight and my eyes are squinted almost shut from looking at this monitor, I'll get on it tomorrow.

    Look at your other post, there are pics of the shaft. It simply pulls out and it only goes back in one way, just align the tips of the spring with stud in case.
