Water pumps again

[mike_starling]

OK Guys,

I appreciate all of the "you should do it this ways," BUT the situation will not allow ANY of your suggestions that include two rows of belts as I already have three and one is non-negotable (the oil pump).

So ... I'm back to the Explorer pump and front cover, or the Ford hotrot short pump. The rotation of the hot rod pump (M-8501-E351) is normal (that is, CW). It would not requiring cracking the already sealed engine and that is a strong imperative for trying it.

If that pump has a "snout" that would allow using a "cup" shaped pulley ... I can just get it to line up with the exiting plane of the alternator and A/C compressor.

Questions:

1) Does M-8501-E351 have a small snout that would allow the use of a "cup" shaped pulley? and

2) Anyone have a favorite place to buy these things that has good discounts?

Thanks,

 

You are using V belts right?

I think you need to measure how much the groove needs to be offset from the water pump flange, and what diameter you need.

After you have those two dimensions, you can have a pulley made, or hunt for one that is close. If you find a good pulley with more offset than you need, you could add a shim between the pulley and water pump flange to reduce the offset.

That hot rod pump should give clearance for the pulley you need because I'm sure this problem happens with hot rods as well.

Also, call up summit or Jegs and see what their return policy is. You might be able to get an exchange if the hotrod pump won't work.

Lastly, if clearance is tight, the webs that support the water pump shaft can be ground down for clearance. Try to find a pulley that fits first, but if all else fails, grind it.
