How do you change clutch on Yamaha 450 yfz?

Answer 1

depending on what you would like to do, you can drain the oil, or set the bike down on its left side to work on it without havig to drain the oil.

you should get a complete clutch kit with springs, and also a clutch cover gasket.

its possible to get away with reusing the gasket, but it really sucks when it starts leaking in the middle of the dessert.

remove the rear brake lever, and spring, then take loose all the bolts on the clutch cover.

try to lift it off.

if it doesn't want to come loose easily, use a SOFT hammer and tap it from behind.

after you have the cover off, remove the six bolts holding the springs on.

lift off the pressure plate and clutch pack.

soak the new clutch parts in oil, and then set them in place in the same order that the old ones came out.

put the pressure plate back on with new springs, and torque the bolts to 8 ft-lbs.

re-install the clutch cover with a new gasket, and some sort of sealant. I recommend purple loctite anarobic sealant because it never hardens, and cant clog oil passages like silicone.

re-install the rear brake lever and spring.

if you drained the oil, change the filter, and then fill the motor wil oil.

that's pretty much it.

*I forget if this bike has a cable of hydraulic clutch, but if it's cable actuated, you'll need to take loose the cable too.
