E9 – OUTER BOOM CHAIN WEAR
CHECK
MT 1840 …
- Chain wear occurs at a number of locations.
• On the joints, which leads to elongation of the chain.
• On the edge of link plates through contact with the pulleys.
• On the sides of the plates and the protruding pins through contact with the pulley flanges.
• On the alignment of the flats of the extended pins.
CHAIN ELONGATION
We recommend that you perform this operation using the chain checking gauge
(MANITOU part No.: 161583).
- Set the lift truck on its stabilizers, with the boom horizontal.
- Fully extend the telescopes and continue operating the control for a few moments
to properly tension the chains.
- As the chain will likely wear unevenly over its length, divide the chain into 4 equal
sections and check with the gage at the center of each section.

IMPORTANT

If the maximum dimension is exceeded (228,6 mm + 2% = 233,2 mm), replace the pair of chains (contact your dealer).
PLATE EDGE WEAR
As for chain elongation, perform a check in the middle of each equal section using a caliper gage.

IMPORTANT

Above the minimum dimension (24 mm - 2% = 23,5 mm and 15,5 mm -2% = 15,2 mm), replace the pair of chains (contact your dealer).
EXTENDED PIN WEAR
As for chain elongation, perform a check in the middle of each equal section using a caliper gage.
53,6 mm
42,25 mm

IMPORTANT

Above the minimum dimension (53,6 mm - 2% = 52,5 mm and 42,25 mm -2% = 41,4 mm), replace the pair of chains (contact your dealer).
- In addition to wear, the high pressures between the side of the plates and the pulleys may force out material, causing
the joints to seize. Replace the pair of chains in this case also.
ALIGNMENT OF EXTENDED PIN FLATS
Check the chains over their entire length.
- High friction between the plates and the extended pins may cause the pins to turn within the outer plates and thus
come out of their housing.

IMPORTANT

If the flats are not aligned in the longitudinal direction of the chain, replace the pair of chains (contact your dealer).
