•
Tape the winch power cable terminals so that they cannot accidentally reconnect with the
battery terminals when the body is lowered. Also place the disconnected winch power cables
so that they are not trapped and damaged as the body is lowered or in subsequent road trips.
•
Be sure to reconnect the pump power leads to the power pack securely. Electrical power will
be needed to lower the body and loose leads may result in arcing and possibly melting of
terminals.
•
Following the instructions in section 3.2, remove the body prop, lower the body and re-stow
the body prop.
•
Disconnect the power leads at the winch end, noting which lead goes to which terminal.
•
If lifting gear is available to support the winch and headboard assembly, proceed to the next
step. Otherwise remove the winch and its cross-tube by releasing the bolts at each end of the
cross-tube.
•
There are six M12 bolts and nuts securing the Tipper headboard
–
three on each post. Remove
the bottom bolts first then one top bolt each side. Note that two 19 mm across flats spanners
are required because the nuts on the rear are not captive.
•
Remove the nut from the remaining top bolt on one side but do not withdraw the bolt.
•
Use an assistant to maintain contact between the headboard and the trailer body on the
released side and to prevent the headboard tipping forwards at the next stage. Make sure the
loose bolt stays in its hole.
•
Remove the nut from the last remaining bolt but do not withdraw that bolt.
•
Together with the assistant, pull the headboard forwards bringing the two loose bolts with it.
•
Collect up the nuts and bolts and fit them loosely to the headboard for safe-keeping.

Re-fitting Headboard, Tailboard and Sideboards
Rebuilding is essentially the reverse of removal
–
use the exact reverse sequence. However the
following additional points should be noted:
•
The correct tightening torque for M12 bolts involved is 80 Nm (60 lbf.ft). However the anti-
rattle bolts at the bottom of the side-posts and the rear corner pillars should only be
tightened to 40 Nm (30 lbf.ft).
•
Fit and close both sideboards before tightening the anti-rattle bolt at the bottom of the
sidepost when re-fitting the sideboards.
