Carefully start the air motor with reduced air pressure and stop at the top stoke position. Isolate the air
supply to the air motor.
Refit the solvent cup.
Carefully drive the air motor shaft down towards the fluid section.
Upper Packing Replacement
Preventative Maintenance - Pump Paint Packings
Check daily to ensure that there is the correct type of lubricant material present in the solvent cup; this should
be compatible with the material being pumped. Confirmation from the material supplier should be sought to
ensure compatibility to prevent the risk of contamination.
A universal lubricant is available - Wet Sol ‘Plus’ Binks Part Number 863009
Check daily for excessive material leaks into the solvent cup.
Upper Packing Adjustment
Stop the Pump and isolate the air motor air supply.
Relieve all fluid pressure from the pump.
Clean the solvent cup to remove excess leaked material.
Relieve all fluid pressure from the pump.
Use ‘C’ spanners to remove the packing nut (36) from the packing retainer.
Remove all parts and clean using compatible solvent, discard the 4 off chevron packings.
Refit male packing retainer (58) into packing retainer (33). Lubricate the bore with compatible grease and
fit 1 off new chevron packings assembly (35).
Lubricate the thread of the packing nut (36) with anti-seize and fit into the packing retainer (33), hand
tighten only.
Use the ‘C’ spanner to tighten the packing nut (36) and preload the chevron packing, approximate torque
40Nm.
Couple the air motor to the fluid section.
Run the pump at pressure then de-pressurise again, retighten packing nut (36)
Use the ‘C’ spanner to tighten the packing nut (36) and preload the chevron packing, approximate torque
40Nm.
Add a compatible lubricant to the solvent cup of the packing nut (36).
