CB750K1 COUNTERSHAFT BEARING REMOVAL (6304)
« on: June 07, 2008, 11:15:53 AM »
I have to remove the 6304 bearing from the countershaft bearing holder on the outside of the case.  Does anyone have suggestions on how to accomplish this?

I got one out by freezing the assembly, the bearing popped right out then.

If it the one with the groove and clip , you will be pulling the motor and splitting the cases..

Nah, the 6304 bearing on a 750K1 is the one that rides in the countershaft bearing support under the mission cover.

Bearing sits onside #1 in the following pic, no need to split the cases.

Yup, that's the one.  I've got it in the freezer right now, hopefully that will do the trick.
