Introduction
This manual covers both the 4” and 5-5/8” stroke length air motors. When there is a
part difference between the two air motors the 4” stroke is referred by VPH and the 55/8” air motor will be referred by MPH. The reassembly will require the use of removable
Lock Tite® and Lithium grease.
NOTE
Before starting any service work, release fluid and air pressure from
system. Remove the two air lines from the air motor. The air motor
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.

muffler (VPH-4253-01 or MPH-2505-01) and remove the muffler.
2. Remove the four socket head cap screws (F-CS-04C-32-SS) from the valve
block.
3. Unscrew the poly fitting nut from the male elbow (MPH-2539) located on the
side of the valve block. Remove the two end caps (MPH-2521) from the valve
block.
4. Remove the pipe plug (PF-AP-04-SS) from the lower valve block (MPH-2516).
Use a flat head screwdriver on ether of the two valve pistons (MPH-2517) and
rotate until the hole in the valve poppet (MPH-2520) aligns with the pipe plug
port in the lower valve block.
5. Insert a 7/32” hex wrench through the pipe plug port and into the hole in the
valve poppet (MPH-2520). (See Figure 1)
Figure 1
