MPH / VPH – 4250 Series Manual
Rev. 05/2012 Page | 15
Introduction:
This manual covers both the 4” and 5-5/8” stroke length powerheads (VPH-4250 &
MPH-4250). When there is a part difference between the two air motors the 4” stroke is
referred by VPH and the 5-5/8” air motor will be referred by MPH.
NOTE: It is important to have the correct parts drawing for the Powerhead you are
working on. This will assist in identifying the correct part numbers for the
assembly being rebuilt. The procedures will be the same between the different
configurations but some parts will differ.
The reassembly will require the use of removable Loctite® or equivalent thread lock
compound, Lithium grease (08465) and SUPERLUBE O-ring lubricant.
NOTE: Before starting any service work, release fluid and air pressure from
system. Remove the two air lines from the air motor. In some cases the
Powerhead assembly does not have to be completely removed from the system
for service work.
Please read the manual carefully. Follow the steps in the order given, otherwise you
may damage the equipment or injure yourself.
During Disassembly . . .
As you disassemble the equipment, lay out the components in the correct order and
direction, and have all component drawings available to refer to prior to disassembly.
This will help you to reassemble them.
