Hi I’m currently changing the clutch on my 2015 cbr500r and I was wondering how much torque is required for the four bolts that bolt into the pressure plate with the springs. I think it’s 9 ft/lbs but I’m not sure. I wasn’t able to find the answer anywhere. Thanks.

I see 9 ft-lbs or 108 in-lbs.

Try to use an in-lb torque wrench since most ft-lb wrenches may not accurately deliver torque as low a 9 ft-lbs.

Not a link per se. I bought a service manual early on in my short tenure with my '14 CBR500R and still have it:

I ran into an issue. I assembled everything and added oil, but when I released the clutch lever it doesn’t engage the transmission. It seems as though the clutch lever isn’t doing anything. Adjusting the clutch cable didn’t help. Does anyone know how this specific clutch works. It look like when you pull the clutch in it pushes a metal cylinder forward into the plate that holds down the springs, compressing the springs even more. It seems that compressing them more would add friction to the disks and keep the trans engaged, which is not what a clutch is supposed to do.

The CBR500 clutch is "reversed" in that the pressure plate is down in the basket and the springs act to pull it toward the right side of the engine, sandwiching the steels & frictions between the pressure plate and the clutch center.

To disengage you need to press "leftward" against the lifter rod in the center of the clutch assembly.

Remove the clutch cover again. Verify that the lifter rod, bearing and plate (all within the highlighted part of the image I showed in my first reply) are present and assembled correctly. With the lifter-rod installed in the right-side clutch cover, if you rotate the release arm does the lifter rod move in and out?

Do you have a service manual for the bike?

Yes the lifter rod moves in and out. And I don’t have service manual. Just to verify, am I supposed to have 13 plates and disks? Because the plates and disks don’t seem compressed when I squeeze the pressure plate and center cover together.

Looking at the diagram in the service manual I have 13 looks to be the correct number of steels and frictions:



Are you certain the assembly is as shown, including the anti-judder spring and its seat (the two circular items next to the clutch center in the diagram)?

Yes I have the two smaller rings around clutch center in the correct spot. There is a 1/4in gap between friction disk and center clutch even when screws are tightened to 9 ft/lbs. The center clutch is hitting friction plate so it can’t go any tighter. Another problem is the center rod with the barring seems too far in, so the lifter rod barely touches center rod even when clutch lever is pulled and clutch lifter arm is fully to the right.
