PRIMER DISENGAGING UNIT
Maintenance Attention
To remove the disengaging unit, slacken the hose clips and remove the rubber priming
hose. Disengage the primer return spring, and swing the primer upwards and clear of
the disengaging unit.
Disconnect the pipe union on the underside of the disengaging unit and unscrew the
disengaging unit from the bracket.
The primer release pipe may now be removed from the pump body if necessary.
The disengaging unit is dismantled by removing the circlip, washer and rubber cap from
the spindle, then unscrewing the six nuts and washers from the studs in the housing.
The diaphragm should now be examined for deterioration cracks, etc. To dismantle the
diaphragm assembly, unscrew the self-locking nut from the end of the spindle.
When re-assembling the diaphragm assembly, ensure that the diaphragm pressure
plate is fitted and use a new self-locking nut.
