Anatomy of a Clutch Basket Replacement Daniel M. O'Brien, (c) 2003 Converted to PowerPoint by Janice Clanfield, 2008
Put the bike on center stand, not absolutely necessary, but helpful for draining fluids
This is the clutch side of the engine case, where the glass oil sight is
Drain the oil while hot, the chin guard will be removed after draining the oil
Remove the nose piece, and right side fairing, the engine guards keep the fairing from coming off easily, so I had to remove the black piece from the fairing first
And leave the black piece in place, no need to remove it, note the radiator cap, don't remove it yet!
Here are our body parts removed, fairing, chin guard, and nose piece
Remove the lower coolant drain hole, it will drip just a little, put a container under it, remove the radiator cap, and watch out as it comes out fast! there's another drain hold to the right, follow manual
Remove the radiator hoses from the water pump, a 1/4" hand driver works well with a 6mm socket, two hoses need it, other is simple squeeze clamp, note the pan below to catch incidental coolant and oil (don't tell my spouse, but its her turkey pan)
Water pump housing showing the three connections with hoses removed (I don't know why, but this picture is one of my favorite)
Need to remove right hand footpeg, again, hex bit sockets are the best
The brakelight switch spring comes off the brake pedal and just moves up out of the way
Remove the water pump housing (remove all the housing perimeter bolts), leaving the "O" ring (not really an O is it?), note the impeller, you will have to turn this to get the impeller shaft into its gear when installing the clutch cover
Then remove the clutch cover housing by removing all the perimeter bolts first, then it just pulls off, there will be some extra drainage, thus the pan
Next, again with hex bit socket, remove the clutch pressure plate springs, loosen all first, then remove opposite bolts, when down to last two loosen both equally until they come out, remove top pressure plate
The pressure plate removed, leaves the clutch plates, also remove the clutch rod, bearings and washer are likely stuck to the inside of the top pressure plate
Remove the clutch plates (drive and driven), in order, and put them on the pressure plate, note the clutch rod, bearings, and washer
All that is left is the inner hub that drives the transmission and the clutch basket that is driven by the engine, note the big nut in the center (30mm or 1 3/16")
This nut holds it all together, must relieve the detent with a hammer and chisel
Air impact wrench to make short work of the nut, remove inner hub, leaving
The bearings the basket rides on (it will slip forward when you pull the clutch basket off), and below is the oil pump gear driven by the clutch basket (make note of this gear, you must align the gear when putting the new clutch basket on!)
Note the brass screen trapping major metal filings so they don't flow thru the system, below the oil pump gear
The oil pump drive gear is removed from the clutch basket with a ring pliers (see the inner hub next to it)
Removing the ring, gear and a type of keyway that engages the oil pump gear with the clutch basket, these are reused in the new basket
As you go along, keep all related fasteners together in bags, fairing and body parts, clutch cover, and clutch pressure springs
For the installation section, the most important tool is the Service Manual -- don't proceed without it! Torque Specs are in the back if not in the specific procedures (clutch cover, foot peg)
Here are all the parts that we are replacing, clutch basket (comes with new hub sleeve), clutch cover gasket, water pump O ring, clutch hub nut and convex washer. Here's my order, all of these should be replaced together.21200-06811 GEAR ASSY,PRIMA = $182.4809164-24006 WASHER CL SLEEV = $1.4811482-06G00 GASKET,CLUTCH C = $6.5117435-02F00 O-RING,WATER PU = $4.3609159-24010 NUT = $5.25Subtotal: $200.08Shipping: $15.00Grand Total: $215.08
Here's a detail of the new design clutch basket, "I think I'll call him... Lil' John!"
I was suprised to find the clutch hub sleeve with the new basket, not sure why they are replaced as a unit since there is a bearing set that is reused
"There she is, Miss America..." or is that Miss Universe, anyway, she's exposing herself a bit, but don't worry, the doctor will soon take care of this
And then slide the old bearing over the new sleeve and lubricate it well
Install the old oil pump drive gear, keyway, and snap ring on the new clutch basket
Slip clutch basket on the clutch hub and wiggle it back and forth to engage the drive gear, THEN
Wiggle the oil pump drive gear so that it also engages, so you can slide the clutch basket all the way back
Slip on the flat washer and the NEW convex washer, note the orientation of the convex washer
Next with chisel and hammer, make a detent on the clutch hub nut
Close up of the clutch hub nut, this sucker ain't going nowhere!
Put the drive and driven plates back in the order they came out, if you've mixed them up, then you need to review the manual and take measurements to determine which kind of plate goes where
