6.4 DISASSEMBLING THE MACHINE
The disassembling sequences of the amphibious hydraulic undercarriage are as follows:
1.
Disconnect all hydraulic hoses from the center joint and slewing frame. Caution on
hydraulic oil spills. Plug open hoses with caps or plugs.
2.
Remove the hydraulic cylinder pins from the undercarriage hydraulic cylinder brackets
(it is not necessary to remove the hydraulic cylinder from the slewing frame). Use a rope
to tie or hang the hydraulic cylinder to the slewing frame.
3.
Take out all the hex bolts connecting the slewing frames to the crossbeams. Slowly pull
the slewing frame off the crossbeams.
4.
Separate one of the undercarriages apart to allow room to release the crossbeams.
5.
Finally, take out the two crossbeams.
6.
The disassembly process is now complete.
