The seal kit consists of the following:
• large o-ring (1)
• polypak (2)
• dust seal (3)
Figure 6.3 High and Heavy Hitter Plus Mast Seal Kit
Important: Ensure that o-rings are not twisted when placed into the cylinder mast cap.
Twisted o-rings will result in a faulty seal and may cause leaks. Place the large o-
ring (1) through the bottom (threaded side) of the mast cylinder cap (6) into the
first groove above the threads.
1. Install the polypak (2) into the second groove from the top (wrench side) of
the mast cylinder cap (4). Ensure that the side of the polypak (2) with the o-
ring embedded into it faces the pressure side (down).
2. Place the mast cylinder cap (4) on a solid surface, then rest the dust seal (3)
on top of the cap (4) with the open side up. Using a hammer, tap the seal into
place.
