6.4 Tine arm replacement
Tine replacement should be carried out in the following way:
1.
Lower the rotor arms to the ground and make sure the machine is secure.
2.
Shut down the tractor, remove the key and apply the parking brake.
Rotate each arm to be worked on, to the rear outer quadrant of the rotor. Each arm can
be replaced by simply removing the 4 roll pins at the inner end of the tube. Quick-fit tine
arms can be swapped out quickly and easily using linch pins. For a complete arm
replacement, including cam follower, remove the corresponding 3 bolts on the gearbox
and slacken the bolts of the neighbouring arms. Then, pull the complete arm and cam
follower from the gearbox. Note the orientation of the cam follower and save the cover
spacers on either side for reassembly. Before replacing the complete tine arm, it is a
good opportunity to add plenty of grease into the cam itself. The cam follower should
also be well greased. Assemble in the reverse order of disassembly and ensure all
spacers, bolts, washers and nuts are replaced and tightened securely.
