8 Disassembling the New Style Bed Hook
8.1 Remove the pressure control knob from the pump (Refer to Page 3, Section 2).
8.2 Remove the pump rear case (Refer to Page 5, Section 6).
Note : The bed hook brackets are right and left handed.
8.3 Hold a hook plate (Fig 4, Item 20 or 30) in position and remove the four securing screws (Fig 4,
Item 40) from the inside of the pump rear case. Release the hook plate from the rear case and
lift clear.
8.4 If necessary repeat Section 8.3 to remove the other hook plate and bed hook (Fig 4, Item 10).
9 Installing the New Style Bed Hook
Note : Replacement Old Style Bed Hooks are no longer available. The Old Style Rear Case
assembly will not accommodate the New Style Bed Hook so where Old Style Bed Hooks must
be replaced it will be necessary to obtain all the parts listed in Table 8, plus the rear case (Item
30 in Table 6).
Note : For step 9.2, remember to place the left-hand bracket on the right and the right-hand bracket
on the left, since their relative positions will be reversed when they are presented to the rear
case assembly.
9.1 Assembly of the new Pump Filter is in the reverse order of disassembly. Make sure the slots in
the Filter Housing Plates (Fig 4, Item 20) are uppermost in the positions shown in Fig 4.
9.2 Lay the left-hand (Fig 4, Item 20) and the right-hand (Fig 4, Item 30) brackets on a hard flat
surface with their rubber pads face down and their shaped heads pointing inward.
9.3 Ensure the bed hook (Fig 4, Item 10) is correctly placed to the left-hand and right-hand slots
where the coating has been removed. Firmly press home the bed hook until it clicks into place.
9.4 Lay the rear case assembly, on a hard flat surface, with its back uppermost. Turn over the bed
hook subassembly and place into the rear case assembly.
9.5 Position one bracket and press it firmly until it clicks into place. Repeat this process for the
other bracket.
9.6 Turn over the rear case assembly and fit four securing screws to each bracket.
9.7 Assemble the rear case to the pump (Refer to Page 5, Section 7).
9.8 Install the pressure control knob (Refer to Page 3, Section 3).
