Slack the portion of the chain that normally passed over the lift-wheel. examine the
interlink area for the point of maximum wear. Measure and record the stock
diameter at this point of the link. Then
measure stock diameter in the same
area on a link that does not pass over
the lift wheel (use the link adjacent to
the loose end link for this purpose).
Compare these two measurements. If
the stock diameter of the worn link is
0.254 mm(or more).
Less than the stock diameter of the
unworn link, the chain must be replaced.
The chain length is 3 meter and it has 157 Knots.FIG 2.2 is specific dimensions of
the chain.
Lubrication
The gears are packed at assembly with grease and should not need to be
renewed unless the gears have been removed from the housing and degreased.
Bearing.
Rotor bearing are pre-lubricated and require no lubrication. Needle bearings are
packed at assembly with grease and should not to be relubricated. However, if the
housings, lift-wheel or sheave wheel have been degreased, these bearing should
be greased using lithium grease.
