7.6.3 Priming Tank Assembly Instructions
Note:This may be done before fitting the Inlet duct
(1) to the pump casing but is best done
after fitting to the pump to ensure stability
and ease of assembly.
1. Insert the knitmesh filter (10) into the
priming tank (3)
2. Fit the gasket (2) to the inlet duct (1), mount
the priming tank in position and fasten in
place with screws (24) and washers (24a &
24b).
3. Fit the long stud (12) to the filter carrier (11)
using the nut (13) to lock it into position and
fit ‘O’ ring (16) to filter carrier (11).
4. Fit the carrier assembly to the filter housing
(4) and retain by three studs, washers and
nuts (22, 23 &23a).
5. Feed the fine filter element (18) into the
housing and fit the filter retainer (19), do not
over-tighten the retainer as this may
damage the filter element.
6. Fit the ‘O’ ring (21) to the filter cover (20)
and fit this to the filter housing, retained in
position with three washer and knobs (15 &
17).
7. Mount the filter assembly on the priming
tank using gasket (5) and eight studs
washers and nuts (6,8 & 7).
8. Fit the fibre washer (25a) on the adaptor
(25) and using PTFE tape to seal it fit this to
the filter carrier.
9. Again using PTFE tape fit the solenoid
valve (26) to the adaptor having fitted the
bush (27) and breather cap (28) to the
solenoid valve.
10. Finally using PTFE tape to seal the threads
fit the pipe fittings (29, 30 & 31) to suit the
required direction of the vacuum hose.
7.7 Pump End Final Assembly
(Refer to Pump Parts Diagram 7.3.2)
1. If the Inlet duct was not fitted to the pump
casing for assembly of the priming tank, fit
the priming tank assembly to the pump
using ‘O’ ring (57) to seal the joint and
retain by studs washers and nuts (54 55,
55a & 55b).
(Refer to Coalescer Parts Diagram 7.4.3)
2. Fit the vacuum pump to the coalescer using
the gasket 33 and retain by studs, washers
and nuts (34 36 & 37).
3. Fit the coalescer assembly complete with
the vacuum pump to the pump bearing
housing using studs (35) and washers and
nuts (36 & 37).
(Refer to Drive Belt Parts Diagram 7.11.1)
4. Fit the key (pump parts diagram item 11) to
the pump shaft, fit the Taperlock bush (2) to
the pulley (1) and slide this assembly on to
the pump shaft.
5. Align the pulley with the vacuum pump
pulley and tighten the grub screws to lock
the pulley into position on the shaft.
6. Remove each grub screw in turn and apply
Loctite 577 to the threads, refit and tighten.
