My water pump pulley is not pushed back far enough and the belt that I used has the wrong V. My question is, what is the correct belt for the 235 and does anyone have a part number for it? I am running an alternator with a stock pulley. Thanks for the help.

Did you make your own brackets for the alternator? Are all the pulleys inline with each other? | | | | | Joined: Jul 2008 Posts: 93 Shop Shark | | Shop Shark Joined: Jul 2008 Posts: 93 | Have you tried a new belt? If a cord is broken in the belt it will keep rolling over. That's why it is important to not pry a belt on. | | | | | Joined: Jan 2012 Posts: 162 Wrench Fetcher | | Wrench Fetcher Joined: Jan 2012 Posts: 162 | No. That's why I'm asking for the right size belt. I used the one that was on it when I got it and judging by all the other stuff th P.O. did, I'm not 100% certain it's the right belt. | | | | | Joined: Jan 2010 Posts: 4,263 Shop Shark | | Shop Shark Joined: Jan 2010 Posts: 4,263 | I'm usinging a gates 7417 | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | Which belt is correct depends on year and conversions done.
If you take your belt to an auto store they can measure it for replacement.
