Spindle leaking grease

[Savedman]

I have an ISX800. The blade drive belt and pulley system has started vibrating when i engage the blades. I have checked the blades which seem to be alright. What i have found is grease squirting out from under the left spindle trash cover washer. The only thing i can figure is the spindle is bent and causing the grease to leak. Has anyone else had this problem

More likely you have a warn bearing. Grab the tip of the blade an vigorously move it up/down - there should be very little, if any, movement.
If you have movement, its either new bearings or a new spindle with bearing included.
