Replace clutch cushions on 2015 fj09


Recommended Posts


2015 fj09. Had a buzzing/ zzzzzzzz/ vibration at idle, off throttle, low speed, and 4-5k rpm maintained speed at low load. Reading many posts on this and fz09 forums I concluded the clutch cushions were loose and sloppy.


The clutch disassembly and reassembly is covered well in other posts. I suggest using a dowel rod to keep parts in their proper sequence.

Be sure to put rags or paper towels in the gap between the oil pump and interior engine sump. Can you imagine how unhappy you would be if debris or parts fell into the motor!

1. To slide the basket off the shaft the oil pump sprocket has to be unbolted from the oil pump. I probably had 3/32" play between the basket and driven gear due to cushion deterioration.

2. There are eight 6mm x 20mm rivets holding the basket to the driven gear. I used a 40 grit flap wheel to remove the rivet heads and punched out the rivets. Could not source 6mm rivets.

3. The 6mm bored holes would be perfectly sized to tap for M7 bolts. Could not source M7 bolts. I decided to either use .250 rivets x .875 length or 5/16"-18 x 3/4". Could not source .250 rivets. Decided on 5/16"-18 bolts.

4. There is a clearance issue between the oil pump chain and rivets to consider. Measuring the clearance between the oil pump chain and driven gear backing plate was approximately .135" to .140". Any fastener must finally fit.

5. The next decision was bolt head type and material.  Button hex socket head, socket hex head, din 7991 flathead hex socket, hex head. Material, stainless, steel, g2, g5, g8. Decided on hex head grade 2, steel.

6. I had a 3/4" flat steel plate and drilled and tapped for the bolt, 5/16"-18. I screwed the bolts into the plate and using a 40 grit flap disc, shaved the bolt heads to .125" thickness. (Gave me a solid secure base to hold the bolts while grinding)

5. I drilled the clutch basket bosses with F drill and tapped with the appropriate tap. I drilled out the holes on the driven gear backing plate to 5/16".

6. Clean, clean, and reclean all parts.

7. Install the cushions on the bosses. Factory cushions have letters on one side and are installed in the up, or visible, position. The Hinson replacement cushion kit,CU216, are not marked. The bosses are also tapered that you know assembly is correct. 

8. Install the two steel rings between the basket and driven gear. The flat ring goes first against the basket. The tapered ring (think concave spring washer) is next. The concave towards the basket. Next in the assembly is the driven gear. Then the backing plate (which is marked OUT, visible to you). Add a drop of red loctite to each bolt and assemble. Torque the bolts to 106 in./lb. (I torqued all the 5/16"and M6 bolts to 106 in./lb.)

9. Reinstall the clutch basket in reverse order and your done.

I installed the slipper clutch kit.

To be clear, the vibration inherent with the triple is still there. (That what we like) The offensive vibration is gone.


see ya

Oh, I forgot....

Attach the oil pump chain on the gear prior to installing the repaired clutch basket. 

Install the oil pump sprocket and secure to the oil pump, 106 in./lb. Torque to the bolt. (Check that the flats on the pump shaft are mated to the sprocket correctly)

Ill be doing this as well this winter however i might be going with polyurethane bushings. I was offered a new clutch basket under warranty but I said not to bother, just going to do the same thing. FYI mine is a 2020 and has seen many clutch up wheelies in it's short 7.5k miles.

Hi David,

Thank you for the update. I originally thought I could remove the clutch basket bushing(inner race) and needle bearing but was concerned about the needles falling out of their cages.. ( didn't know the construction of the bearing).

see ya

I know this is a really really old thread, but if anyone has the knowledge.....(my 2015 FJ09 only has 4500 miles, but oh my goodness what a racket it makes, but quietens in neutral when I pull the clutch in.

Just wondering if buying a new clutch basket could have been an option for OP (by the way Bill, if you are still around - thank you

Hi, My 2015 also has this issue and have gone over many videos on this and am planning to do it as well.  Yes, you can replace the basket/driven gear assembly which was upgraded sometime after our year...maybe an improved part?  But here in CAN, the new part is 600$ +tx. This fix should be <200$ for me. If my basket is worn badly or any cracks, I'll have to replace.  Xmas list i guess.

*mine has 30k km.

My 15 has 60k miles and I installed the slipper clutch years ago for reduced pull and it's other benefits but rarely need or want to use (activate) it.  I can't remember if it always has or developed later the rattling noise at idle when in neutral with the clutch out but it quiets considerably when pulled in.

It shifts great and has a very wide clutch friction zone, which makes controlling speed and back-torque a real pleasure.  I've read how many feel the friction zone is too narrow and abrubt?

It is also smooth and to me relatively vibration free cruising at highway speeds, so much so I often forget to upshift to 5th (which seems a bit rougher; my steed loves 4th gear) and then 6th doing 70+ mph!!!  However, I seem to get better gas mileage irunning high in 4th and 5th?

During spirited and urban riding, maybe my higher concentration level is such I don't notice vibes but I have no numbness or tingling during or after long rides.

Now maybe I'm just used to moderate to heavy vibration coming from Brit singles and twins.  I also think my 98 VTR1000F is super smooth, so much so it's sneaky fast!

I also packed the now Street Naked bars full and solid with Copperhead BBs; a mod I do on all my bikes.  The adjustable clip-ons on my VTR are solid aluminum bar and seem to change the natural harmonic frequency to a pleasant  very dull throb.

Anyway, to the subject at hand, I'm afraid to "fix" something that, knock on plastic, doesn't bother me (at least with earplugs, music and wind noise), and screw up the PDG shifting (I can upshift without clutching from 3rd thru 6th, and if I'm careful even from 2nd) and, to me at least, a fairly quiet (stock exhaust but Vcyclenut ECU flash and -01 clutch cable) and comfortable fastest red 15...

Or am I just a dull twit, and/or oblivious being in such bliss to simply be out flying low on somewhat curvey, quiet back country roads, and also while droning the Slab listening to great road music getting to said roads???
