belt issue

[DanHovland]

48" rider sheds drive belt
when in neutral and running belt engages and clutch/brake pedal bounces as belt drives
pulley alignment?
Can clutch brake be adjusted so belt doesn't engage in neutral? when not engaged seems loose and wobbly
new belt in use
this unit has had axle damage but put back together ok

A bouncing pedal happens because something is applying & releasing tension to the belt.
This can be a lump of debris stuck in the V of a pulley, a pulley with a flat spot or a duff bearing.
An old belt with a chunck out of it can also cause pedal bounce. so that should not be your problem .
If the transmission steady bracket or bolts are loose that can also cause pedal bounce .

Was this happening before you replaced the belt ?
Did you measure the new belt against the old belt ?
Did you fit a clutching ( wrapped ) belt, or a plain unwrapped belt ?

This is of course general advice if you want specific replies then you need to post the model number from the tag under the seat .
