Milodon Chrysler Aluminum Hemi & Wedge Oil Pump 21815 - Manual (Page 2)

6. The depth of the gear set in the pump housing is very important in the pump's ability to
prime. This pump has been factory measured to be between .0015" and .004", any less will
score the cover, any more will result in poor priming. If you replace the gears this will need
to be checked at that time.
All these inspections should be done upon initial installation of oil pump. The oil pump should
be bolted to the block and must be turned by hand to check for any interference problems.
This Milodon Oil Pump is guaranteed for any defects due to workmanship or material. If any
problems with pump are detected, pump should be returned to Milodon before it is run on
engine.
