When working in cold weather or using a thicker grease, keep grease thin for easy workability in one of the following ways:
• Mix some oil (SAE30) with grease. Shake the bucket & press the mixture thoroughly to remove any air pockets
• Heat grease bucket with a Barrel Warmer or Heating Jacket. The temperature should be kept at 0 - 30°C (32 - 86°F)
PUMP DISASSEMBLY & REASSEMBLY
• Steel Ball (8) must rest evenly on its seat over Non
Return Body (7). Also, Steel Ball (8) must rest on
the narrower edge of Plunger Spring (9) otherwise
the ball will fall into the spring causing pump
failure.
• Always lubricate O-rings and seals with grease
before fitting. They must be protected from sharp
edges when being fitted. Lubricate all moving parts
with grease.
• When troubleshooting, be on a lookout for dirt
in valves / ball seats, damaged O-ring / seal &
scratches in sealing surfaces.
• Apply thread sealant to ensure leak-proof operation.
