| Milodon Recommended Oil Pump |
| By John - 01/11/2001 8:49:35 PM; IP 142.177.94.29 |
Back again with another question. Anybody have any experience with the Melling M83HV pump? The following is my e-mail to Melling and their response. I'm a little unclear by what Melling means by "sit farther down in the pan" and "I don't think this would fit very well" Would I need a longer intermediate driveshaft? I have a FPP shaft now that is 5/16 on one end and 1/4 on the other, but it is standard length. This M83HV pump sounds like excessively High Volume to me if the georotor is 2" taller than the M57HV. Check the difference in hot idle pressure as per the Melling response below. Any input would be appreciated.

The M-57HV takes a 1/4 intermediate drive shaft
The M-83HV takes a 5/16 intermediate drive shaft
The M-83HV is 2" taller and would sit farther down in the pan. I don't
think this would fit very well.
The pressure at idle is: M-57HV 32 psi / M-83HV 42 psi
At by-pass is: M-57HV 75 psi / M-83HV 76 psi
