MLC165-1 OPERATOR MANUAL SETUP AND INSTALLATION
Remove Crane Counterweight
See Figure 4-51.
NOTE The counterweight must be removed over the drive
end of the crawlers, not over the front roller end.
This is because the crawlers may be longer over
the front than the rear due to tread adjustment.
1. If not already done, pin the shackles (1, View D) and
handling chains (2) to the lifting links (3).
Make sure the handling chains are not tangled up or
hooked on adjacent parts.
2. Start the engine.
3. Using the switch on the remote control, extend the
counterweight-handling cylinders (4, View C) until the
handling chains (2) are taut.
4. Using the switch on the remote control, disengage the
inner counterweight pins (5, View B).
5. Make sure the inner connecting pins (5) are fully
disengaged.
6. Remove the outer counterweight pins (6, View D).
7. Using the switch on the remote control, fully retract the
counterweight-handling cylinders (4, View A) to lower
the counterweight tray (7) onto blocking at ground level.
Block only as shown in Figure 4-29 on page 4-32
or
damage to the tray will occur.
