Anatomy of a Clutch Basket Replacement

Put the bike on center stand not absolutely necessary but helpful for draining fluids l.jpg

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 l.jpg

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 l.jpg

Drain the oil while hot, the chin guard will be removed after draining the oil


Slide5 l.jpg

A set of hex bits sockets really help a lot


Slide6 l.jpg

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 l.jpg

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 l.jpg

Here are our body parts removed, fairing, chin guard, and nose piece


Next we drain the coolant l.jpg

Next we drain the coolant


Slide10 l.jpg

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


Slide11 l.jpg

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)


Slide12 l.jpg

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 l.jpg

Need to remove right hand footpeg, again, hex bit sockets are the best


Peg and brake pedal come off as unit twist out of the way l.jpg

Peg and brake pedal come off as unit, twist out of the way


The brakelight switch spring comes off the brake pedal and just moves up out of the way l.jpg

The brakelight switch spring comes off the brake pedal and just moves up out of the way


Slide16 l.jpg

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


Slide17 l.jpg

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


Slide18 l.jpg

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


Slide19 l.jpg

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


Slide20 l.jpg

Remove the clutch plates (drive and driven), in order, and put them on the pressure plate, note the clutch rod, bearings, and washer


Slide21 l.jpg

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")


Slide22 l.jpg

This nut holds it all together, must relieve the detent with a hammer and chisel


Slide23 l.jpg

Holding the hub with clutch hub tool, use socket and


Slide24 l.jpg

Air impact wrench to make short work of the nut, remove inner hub, leaving


Slide25 l.jpg

The clutch basket which just slides off exposing


Slide26 l.jpg

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!)


Slide27 l.jpg

Note the brass screen trapping major metal filings so they don't flow thru the system, below the oil pump gear


Slide28 l.jpg

The oil pump drive gear is removed from the clutch basket with a ring pliers (see the inner hub next to it)


Slide29 l.jpg

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


Slide30 l.jpg

As you go along, keep all related fasteners together in bags, fairing and body parts, clutch cover, and clutch pressure springs


Slide31 l.jpg

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)


Slide32 l.jpg

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


Slide33 l.jpg

Here's a detail of the new design clutch basket, "I think I'll call him... Lil' John!"


Slide34 l.jpg

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


Slide35 l.jpg

"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


Slide37 l.jpg

And then slide the old bearing over the new sleeve and lubricate it well


Slide38 l.jpg

Install the old oil pump drive gear, keyway, and snap ring on the new clutch basket


Slide39 l.jpg

Slip clutch basket on the clutch hub and wiggle it back and forth to engage

the drive gear, THEN


Slide40 l.jpg

Wiggle the oil pump drive gear so that it also engages, so you can

slide the clutch basket all the way back


Slide41 l.jpg

Slip on thrust bearing washer, and then the inner hub


Slide42 l.jpg

Slip on the flat washer and the NEW convex washer,

note the orientation of the convex washer


Slide43 l.jpg

Put on the new clutch hub nut


Slide45 l.jpg

Next with chisel and hammer, make a detent on the clutch hub nut


Slide46 l.jpg

Close up of the clutch hub nut, this sucker ain't going nowhere!


Slide47 l.jpg

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


Slide48 l.jpg

Fuzzy picture of last drive plate, goes into OTHER slot


Slide49 l.jpg

Reinstall clutch push rod, oiled bearings and flat washer


Slide50 l.jpg

Reinstall pressure plate


Slide51 l.jpg

And pressure plate spring, hand tightened


Slide52 l.jpg

Tighten them down in a diagonal fashion, torquing to specs (read the manual)


Slide53 l.jpg

All done, nicely torqued


Slide54 l.jpg

Install the new gasket


Slide55 l.jpg

Note the slot in the upper gear....


Slide56 l.jpg

This slot will match the tab on water pump impellor, you may have to

turn the impeller to get the tab to line up with the slot on the gear


Slide57 l.jpg

Put the clutch cover back on, aligning everything including the water pump impeller, should slip on all the way around by hand, ya, you can hit it with your fist, but it must fit flat before putting in the bolts


Slide58 l.jpg

Put the "O" ring into the water pump housing cover, manual

says to apply a little grease to the O-ring


Slide59 l.jpg

Sort out all the bolts and put them into the holes accordingly, hint: the three longest go into the water pump housing, torque it all down by slowly tightening opposite bolts a little at a time, torque to specifications, go slow!


Slide60 l.jpg

Now put all the hoses back to proper places


Slide61 l.jpg

Install the foot peg, torque to specifications


Slide62 l.jpg

Refill crankcase with favorite oil


Slide64 l.jpg

Follow service manual procedures for clearing air in the coolant system, keep topping off. Several starts, bike on side stand, heat/cool cycles, etc, to clear the air. May still suck coolant out of the overflow tank next few days


Slide65 l.jpg

While engine is running, heating, put on chin guard (the "big-o" screw driver handle was used to tap the thermostat housing on the opposite side while the engine was running to dislodge any air bubbles)


Slide66 l.jpg

Button everything up, right side fairing, nose piece, AND YOU ARE DONE!
