Pump Head Service

With repeated use, the gaskets of any pump will begin to wear. The PFP-5 pump head uses two gaskets that may be reversed to gain more service. The gaskets may also be replaced. Both Presta and Schrader gaskets are identical. There is a large hole and a small hole at the end of each gasket. Gaskets are simply reversed and moved to the adjacent hole to gain fresh material for engaging the inner tube valve.

It is first necessary to disassemble the pump alloy head assembly. Place pump head lever is in the up or open position.

1. Use a small punch or similar tool and tap out the lever pin from the head. Pin must have a hole or gap as in a vise in order to disengage from the pump head.

2. Push out gaskets and inner parts of pump head. Push from valve side toward lever side of head.

3. Continue to push from the Schrader hole and presta hole alternatively to remove the Schrader and presta ball-seats from head housing.

4. Lay the parts out in the corrrect orientation. Use care not to misplace the rubber ball.

5. Reverse/Replace both gaskets. Schrader and presta gaskets are identical. Presta side will have smaller opening toward inner tube valve. Schrader side will have larger side toward inner tube valve. Note head housing is marked for Presta and Schrader, replace gaskets accordingly. Push on backside of gaskets until gaskets are fully seated. Install head ball between ball-seats. Ball-seat with cross-shaped stud is Schrader side, and the seat with the hole is the presta side. Install ball seats on top of gasket accordingly. Push ball seats from backside to fully seat them against gaskets.
6. Install and press seat retainer until fully seated.
7. Install lever in open position and install lever pin. Push or tap pin fully in place.
8. Pump head assembly is ready for use.
