5.5 Chassis Maintenance
It is possible to work on individual components of the
chassis without removing either the engine or the
pump unit. In all cases work should be undertaken on
level ground and care should be exercised to ensure
that the pump set is fully immobilised. If the chassis is
to be completely dismantled, both the engine and
pump unit should be removed in compliance with the
requirements of Health and Safety at Work Act, 1975.
1. To remove the fuel tank:
a) Drain the fuel by removing the drain plug and
washer.
b) Disconnect the fuel feed and return lines.
c) Place suitable supports beneath the tank and
remove the four nuts bolts and washers, the
access to the nuts and washers being inside
the main chassis members. The tank can
then be slid from beneath the chassis,.
2. To clean the fuel feed filter:
a) Remove the three set bolts and washers.
b) Lift the filter from the tank, taking care not to
lose the gasket.
NOTE: The filter can be removed for cleaning without
removing the tank from the chassis.
3. To remove the front axle:
a) Support the chassis beneath either the fuel
tank ensuring that the weight is taken on a
suitable piece of wood extending the full width
of the tank, or underneath the main chassis
members.
b) Remove the split pins and washers retaining
the wheels and slide the wheels from the
axle.
c) Remove the split pin and washer. From one
side only of the draw bar pivot pin, slide the
pin free of the pivot and draw bar thus
allowing the draw bar to come away from the
assembly.
d) Remove the split pin and washer from one
end of axle pivot pin and slide the pin clear of
the pivot and axle thus freeing the axle.
4. The front axle pivot locking system is designed as
a backup to the single bolt fixing. To remove
pivot:
a) Bend back lock washer and release the set
bolt lock washer and pivot topcap.
b) Drop the pivot clear of the chassis member.
NOTE : If the engine is in place on the chassis the
access to the set bolt is from beneath the engine
between the chassis members.
c) Extract and replace spring roll pin if damaged,
from top of pivot.
5. To remove the rear axle:
a) Support the chassis and remove the wheels
as described in Instruction 3 of this Section.
b) Release the four horizontally disposed nuts,
bolts, and spring washers and the two vertical
nuts, bolts, spring and taper washers.
6. To remove the lifting eye remove the four set bolts
and spring washers.
7. Reassembly is a reverse of the above, ensuring
that the wheel hubs, axles, pivot, pivot turntable,
axle pivot pin and drawbar pin are thoroughly
cleaned and liberally greased. Renew the fuel
feed filter gasket if necessary.
NOTE: When placing pivot top cap on top of pivot,
ensure the top cap locates correctly over the spring roll
pin in top of pivot shaft. Also when placing the lock
washer with fixing bolt in place over the pivot top cap,
ensure small tab locates in second hole of the pivot top
cap - the first hole locating the spring roll pin. Always
use new lock washer. Finally bending up in one place
to lock against the flat of the setbolt hexagon.
5.6 Supersilent Canopy - Canopy
Removal
To remove the canopy proceed as follows:
1. Disconnect the battery positive and negative and
remove the battery assembly.
2. Disconnect exhaust pipework within canopy
having first removed insulation blanket.
3. Disconnect emergency stop wiring plugs from stop
buttons from within canopy. Tie up onto engine to
prevent damage to wiring.
4. Remove suction and discharge aperture cover
plates. Remove foam plugs and rubber blanking
gasket.
5. Remove discharge fitting and extension piece
from discharge flange of pump.
6. In each corner of the skid, working up through the
upper flange of the skid base are four M16
screws. Remove these in turn to release the
canopy from the corners of the skid base.
7. With the corners released undo the M24 nyloc
nuts from the centre lifting studs. The studs are
locked internally and will not turn beyond a few
degrees of movement. When these are both
released the canopy is ready to be lifted clear.
