Maintenance

Disconnect pump from system and remove to a clean, well lit work bench with access to a vice, tools, seal
kits and spares. All parts removed for inspection should be washed in a suitable degreasing agent such
as Blue Gold or equivalent. Inspect all moving parts for wear or scratches. Damaged parts should be
replaced. It is recommended that all seals and o-rings are replaced. Specially packed seal kits are
available for:
Air Cycling Valve
Air Drive Section
Liquid Sections - D14STD-125
Liquid Sections - D14SFD-125
Liquid Sections - D14STD-315
Liquid Sections - D14SFD-315
Cycling Valve Section
The internal components of the air cycling valve should be removed from the retaining plate end. The two
flat bumpers P/N 50008 should be inspected for wear. Prior to reassembly Haskel silicone grease P/N
50866 should be applied liberally to all components for ease of re-assembly.
NOTE: The 568030-2 rings on either end of the 17634 sleeve are installed as follows: Seat the inside end
o-ring down on bumper before installing the sleeve. Seat the outside end o-ring on end of sleeve by using
the 50101 cap as a tool before installing the second bumper.
Drive Section
The air drive section can be dismantled for inspection by removing the five tie rods and then pulling the
air caps in opposite directions. To replace the 14" drive o-ring seal around the exposed air piston, one
cotter pin and connecting rod must first be disconnected.
Carefully inspect pilot valve stem seal on both end caps. Do not try to reuse retaining ring if removed.
Install new retaining ring by inverting the pilot valve as a mandrel to center the retaining ring. Then lightly
hammer the pilot valve against the retaining ring. The rubber seat on the valve will then force the 'legs' of
the retaining ring to deflect equally.
