Doosan DX235LCR Manual Instruction Extract:

Arm Installation Procedure
Reattach the base of the arm cylinder to the mounting point on top of the boom.
Begin with the arm securely supported on blocking in front of the excavator. Pregrease the mounting pin for the rod end of the arm cylinder and push it through the ears on the end of the arm.
Attach a sling around that mounting pin and lift the arm with an assist crane until it is in position for the boom-arm pin connection to be made.
Relieve hydraulic pressure from all points of the system before any hydraulic lines are opened, then carefully assemble hydraulic connections to the arm cylinder.
Remove the sling from around the rod end arm cylinder pin, withdraw the pin and lift the body of the arm cylinder to re-pin the mounting connection.

Boom Installation Procedure
Before reassembling the attachment, make sure to inspect all bushings and pivot points of each section. To avoid damaging the seats, bushings should never be hammered or chiseled out of their seats.
Installation is otherwise a reversal of the removal procedures.

START-UP PROCEDURES
Once the boom has been serviced, it should be lubricated as outlined in the initial start-up procedures of the operation manual. Refer
