Do you have to remove the pump to change drive belt?
Hi Phunapts
Here is the service manual, see page 23

I did one of these about 2 weeks ago. It is not difficult technically, but it is hard and you need to support the motor as it comes off, and may have to remove a support spring to make the job easier (not required but we did). I recommend you have a strong friend help you (we used Anthony, a former Army ranger, college football player and all around good guy).
Good luck and let us know how it turns out.
