4.2.2 Side Walls
Remove the 90mm pin and keeper plate from the side walls. Apply grease to the inside of the
wiper seals in the main pivot bushes of the rear frame. Lift the side walls using chains attached to
the lifting provisions provided (note: adjust chain lengths so cutting edge is horizontal). The side
walls can either be lowered in place or brought in from the front. The side wings of the side wall
fit between the bowl and the rear frame. Take care to ensure the pin hole in the side walls aligns
with the bush so that the pin can be inserted without damaging the wiper seals.
Once the side wall is in place and the pin keeper is bolted up tight the main lift cylinder pins can
be removed and the main lift cylinders installed. Install the top pin first using an anti-seize
compound on the pin. The cylinders are usually shipped fully retracted, to extend the cylinder to
install the lower pin, remove the port plugs and, with a rag to reduce air leakage, blow
compressed air into the top cylinder port. Once the bearing is close to aligning, a pry bar can be
used to fine tune the alignment. Install the bottom pin as per the top pin.
Figure 4.2 Assembly Step 2
NOTE: Damaging the wiper seals during assembly voids the warranty on that bush as it is
critical that dirt and dust is kept out of the bush to maintain a full service life.
NOTE: The pins consist of a hard chrome shaft and is zinc plated after the pin is machined and
fabricated. There can be a lip where the zinc finishes and the chrome starts. This is typically
filed down from the factory but if the pin fails to go into the cylinder clevis easily check this
and file the zinc down to suit.
