I'm planning to go from my 7# pulley to a 9#. Is there enough adjustment to tighten my current belt or do I need another? Thanks for your help

 

Look at your adjuster and see how much room you have for adjusting. You can probably do the belt change with out problems. If the adjuster is about maxed out then you may need a shorter belt.

Tell us what length belt you have on now.

If you have a Comptech you will need a smaller belt. Check out the link Sideways posted, the belt size you need is listed.
