Split Web Drive Sprockets
Split web drive sprockets (item 1, fig 33) on some web drive shafts. The sprockets allow
for worn sprockets to be replaced or alternative pitch sprockets to be fitted without
dismantling the drive shafts. Most drive sprockets will have been split on initial
installation, but if not, they should be split with a hammer and sharp chisel. Before
splitting a sprocket on or off the machine, remove the fixing bolts (item 2, fig 33). Keep
the split halves of the sprockets in the correct pairs to prevent mis-match when fitting.
Maintenance of the Mechanical Drives
Drive chains must be maintained at the correct tension. Maintaining correct tension,
alignment and lubrication will ensure the efficient running of the harvester and prolong
the life of the drive components. Adjust the chains to give positive drive without undue
stretching. Where plastic chain tensioner or guides are fitted, these will show fairly rapid
wear initially but will settle down when the chain rollers rather than the chain side plates
come into contact with the plastic.
The input drive shaft from the tractor PTO should be checked for damage regularly and
the inner and outer tubes checked to ensure a free sliding movement. Binding between
the input drive shaft components will cause severe end loading on the gearbox input
shaft leading to premature failure of the gearbox.
Maintenance of the Electrical System
Trouble shooting of the control system must be carried out by a competent engineer
familiar with electrical servicing. Items such as the proportional valve control cards and
the control circuit boards may be damaged if incorrectly connected.
New Machines
It is important during the first few weeks with a new machine to keep a regular check for
any bolts, screws, connections etc. which may work loose during this initial working
period.
