5.9 Supersilent Canopy – Canopy
Refitting
To refit the canopy proceed as follows:
1. Re-sling the canopy as for removal and lift into
position. Take care not to damage the radiator
when positioning. Lower onto skid base checking
for alignment of the lifting studs.
2. When down and before fitting any fixings check
that the radiator overflow pipe is not trapped by
the canopy bulkhead. Release if trapped.
3. Refit canopy lifting stud nuts and four corner fixing
screws. Adjust alignment if necessary and tighten
corner screws then stud nuts.
4. Remove eye bolts from canopy roof and replace
with fasteners to prevent water ingress.
5. Refit the delivery extension and fittings and refit
the suction and discharge covers as the reverse of
removal.
6. Reconnect the exhaust extension and refit
insulating cover.
7. Refit the fuel lines and control panel.
8. Refit the air pump exhaust silencer assembly.
9. Reconnect the emergency stop wiring and refit the
battery assembly and coupling guards.
10. Fill with fuel and bleed the system as required.
Test run. Inspect all fasteners after 50 hours of
running.
6 WORKSHOP TOOLS
Major Servicing will always be carried out more quickly
by the use of the following special tools and procedure.
More importantly, their use will help to ensure that new
components are not damaged whilst being fitted.
The tools are simple to employ and have been
designed for use in combination with standard fitter's
tools. For some operations, a simple press, and a
bench complete with a vice will be desirable.
We earnestly advise all pump users to purchase a
complete set of tools.

6.2 Fitting of Actuator Neck Seal
1. Lightly clamp seal installation tool against end of
drive rod by means of capscrew, as shown.
2. Push seal into rear of inner pump body recess
(Part No 0015014000).
3. Clean exposed shaft and tool surfaces, and smear
with soft soap. Carefully slide the actuator neck
seal onto shaft until it abuts against the conical
shoulder.
6.3 Removal of Mechanical Seal
Stationary Seat and Joint Ring
1. Ensure oil is drained from flushing chamber.
Remove impeller and shaft sleeve, complete with
rotating mechanical seal components.
2. Engage tip of removal tool on inside face of seat.
Remove seat by pulling evenly at several
peripheral points.
3. Joint ring can then be collapsed and discarded.
4. To replace, the mechanical seal stationary seat
and joint ring must be assembled together with the
outer face of the joint ring smeared with soft soap,
offered up to the flushing chamber housing and
gently pressed home using a piece of wood.
IMPORTANT ADVICE
New Mechanical Seal Components
must be handled with great care. In
particular, the seal faces must not be
touched by hand and must only come
into contact with clean soft paper that is
free
form abrasive materials.
Premature seal failure is likely to occur
if this advice is not heeded.
