27 Calf section and calf section stay – replacement
This section describes how to replace the calf section and calf section stay. Reference is made
throughout this section to Figure 27 on page 81 and Figure 29 on page 84.
27.1 Removal
To remove the calf section and calf section stay:
27.1.1 Use the ACP to raise the thigh section as far as it will go. Manually disengage the calf section
stay (Fig 27, Item 10) and lift the calf section up and back so that it is vertical.
27.1.2 * Remove and discard the starlock (Fig 27, Item 11) from the calf section stay. Slide the calf
section stay off the calf section (Fig 27, Item 1).
27.1.3 Pry off and discard the hinge infill (Fig 29, Item 06) from the calf/thigh section hinges
(Fig 27, Item 3)/(Fig 29, Item 2). Remove the socket head screws (Fig 29, Item 7) and collect
the washers (Fig 29, Item 8). Do not allow the calf section to fall.
27.1.4 Slide the calf section (Fig 27, Item 1) sideways to disengage the hinges from the thigh section.
Lift the calf section assembly off the bed. Collect the hinge springs (Fig 29, Item 9) and hinge
bushes (Fig 29, Item 10) from the calf section hinges.
27.1.5 * Pull the calf extension (Fig 27, Item 2) out as far as it will go. Push in the plastic latches on
the sides of the two extension bushes (Fig 27, Item 5) and pull the extension assembly out of
the calf section fabrication (Fig 27, Item 1). If required, knock out two roll pins (04-7) and
remove the extension bushes from the calf extension (Fig 27, Item 2).
27.1.6 * Pry off and discard two capped starlocks (Fig 27, Item 12) and remove the calf extension
latch fabrication (Fig 27, Item 13).
27.2 Installation
To install the calf section and calf section stay:
27.2.1 * Fit the calf extension latch fabrication (Fig 27, Item 13) to the mounting holes on the calf
extension (Fig 27, Item 2); fit one end of the latch then slide it across to engage the other end.
Secure with two new capped starlocks (Fig 27, Item 12).
27.2.2 * Slide two new extension bushes (Fig 27, Item 5) onto the calf extension (Fig 27, Item 2).
Drive in two new roll pins (Fig 27, Item 7) to stop the bushes sliding off the tubes. Slide the calf
extension assembly into the calf section (Fig 27, Item 1) until the extension bushes latch into
place.
27.2.3 Remove the two calf section skid mouldings (Fig 27, Item 6) and apply Loctite 495 instant
adhesive to the inside of both skid mouldings. Reinstall them into place on the calf section
fabrication using hand or mallet. If skid mouldings are not present on the fabrication slide plats
- Install new ones, repeating step 3.
Check if paint layer is damaged. If yes, repair the paintwork in accordance with the instructions
contained in the service manual. Use P7906 spray paint.
27.2.4 * Install two hinge bushes (Fig 29, Item 10) and hinge springs (Fig 29, Item 9) into the thigh
half of the calf/thigh section hinges (Fig 29, Item 2).
27.2.5 Holding the calf section horizontal, assemble it to the thigh section by sliding it sideways to
engage the two halves of each hinge. Fit the washers (Fig 29, Item 8) and the socket head
screws (Fig 29, Item 7) to secure the sections together. Make sure the screws are properly
tightened. Fit new hinge infills (Fig 29, Item 6) and (Fig 29, Item 11) to cover the screw heads.
27.2.6 * Manually lift the calf section up and back so that it is vertical. Install the calf section stay
(Fig 27, Item 10) into the lugs on the calf section fabrication (Fig 27, Item 1) and secure it with
a new starlock (Fig 27, Item 11).
27.2.7 * Refer to Figure 28. Manually lower the calf section to a horizontal position; make sure the calf
section stay (A) engages the runners (B) on the sub-frame.
Paragraphs marked * are optional; only follow these if it is necessary to replace
