4.2.7 Swingarm & Rocker Assembly
Remove the swingarm pivot pins from the rear frame as well as the top cylinder pins. Remove the
cylinder pins from the swingarms. Apply grease to the inside of the seals in the swingarms.
Lift the swing arms up and align the bush and the pin boss in the rear frame. Take care to ensure
the pin hole in the rear frame aligns with the bush so that the pin can be inserted without
damaging the wiper seals.
Insert the first pivot pin partially. It should insert by hand. Align and insert the second pivot pin
before inserting the pins all the way home. Assemble the keeper plates with the M16x30 hex
screws. Lower the swingarm onto a block of timber or adjustable stand set to a height of approx.
600 mm.
Lift the hydraulic cylinders and align the top clevis bearing with the pin mounting hole. Insert the
pin as per the procedure used on previous cylinders. Use compressed air to extent the cylinders
so that the lower clevis bearing aligns with the pin mounting holes. Insert the pins and retaining
bolts. Connect the hydraulic lines to the cylinders.
Figure 4.7 Assembly Step 7
NOTE: Anti-seize compound should be applied to all pins which are to be installed into the
hydraulic cylinder clevis bearings.
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.
