Lift chain wear and replacement criteria
New chain length
The distance from the first pin counted to the
last pin counted in a span while the chains are
lifting a small load.
Worn chain length
The distance from the first pin counted to the
last pin counted in a span while the chains are
lifting a small load.
Span
The number of pins in the length(Segment) of
chain to be measured.
Pitch
The distance from the center of one pin to the
center of the next pin.
All chains must be replaced if any link has wear of 3% or more, or if any of the damaged conditions
notes above are found during inspection. Order replacement chains from your HYUNDAI dealer.
Replace all chains as a set. Do not remove factory lubrication or paint new chains. Replace anchor
pins and worn or broken anchors when installing new chains. Adjust tension on new chains.
Lubricate chains when they are installed on the mast.
Please refer to your service manual for additional information on lift chain measurement
and maintenance.

ift chain inspection and measurement
Inspect and lubricate the lift chains every PM (50~250 hours). When operating in corrosive
environments, inspect the chains every 50 hours. During the inspection, check for the following
conditions:
Â
Rust and corrosion, cracked plates, raised or turned pins, tight joints, wear, and worn pins or
holes.
Â
When the pins or holes become worn, the chain becomes longer. When a section of chain is
3% longer than a section of new chain, the chain is worn and must be discarded.
Â
Chain wear can be measured by using a chain scale or a steel tape measure. When checking
chain wear, be sure to measure a segment of chain that moves over a sheave. Do not repair
chains by cutting out the worn section and joining in a new piece. If part of a chain is worn,
replace all the chains on a truck.

ift chain lubrication
Lift chain lubrication is an important part of your maintenance program. The lift chains operate
under heavy loadings and function more safely and have longer life if they are regularly and
correctly lubricated. HYUNDAI chain lubricant is recommended; it is easily sprayed on and
provides superior lubrication. Heavy motor oil may also be used as a lubricant and corrosion
inhibitor.
