Assembly
Renew all parts supplied in the seal kit. Retain the ‘O’ rings
in their grooves with a little petroleum jelly.
Fit seal 10 into cover 12 with open part of the ‘V’ section
downwards. Fit seal 9 into groove in cover and fit seal 8
over seal 9 groove side downwards.
Apply a thin coat of petroleum jelly to both milled gear
pockets of housing 4. Fit housing 4 onto cover 12 with the
two half moon cavities in the housing 4 facing away from
the cover 12. The smaller half moon port cavity must be on
the pressure side of the pump.
Place wear plate 7 on top of seal 10 with bronze face
upwards. The mid section cut out in wear plate 7 must be
on the suction side of the pump.
Lubricate the gears before fitting.
When fitting housings and covers, make sure that marks
made before dismantling are correctly aligned.
Position a suitable sleeve over the shaft to protect the oil
seal 13 from damage on the shaft splines. Press the seal
into the cover to a depth of 5.08 mm (0.20 in) below the
front surface.
