Doosan DX235LCR-5 Manual Instruction Extract:

Replacement of Spool

1. Removing Pilot Cap
Unfasten the two bolts for the pilot cap with a L-wrench (5mm) and remove the cap along with the washer.
(You can remove either of them.)

2. Removing Spool
After fixing the main body and removing the return spring and the spring seat first, pull the spool in the horizontal direction (parallel to the spool hole) to remove it from the main body.
Too much impressed force for disassembly may damage the spool. When the spool is stuck, therefore, push it back smoothly and try to pull the spool while rotating it.
While removing the spool, check which end has the mark.

3. Assembling Spool
Insert the spool into the fixed main body. (Overloaded force may damage the main body or the spool. When the spool is stuck, pull it back and press it smoothly while rotating it.)
Check the direction of the mark, identified during the disassembly operation.
Assemble the spring seat and the spring.

4. Assembling Pilot Cap (on Return Spring Side) Cover the pilot cap on the return spring of the spool, previously assembled to the main body, and fasten it with two bolts at the specified standard torque using a torque wrench (5mm). Check if there is the O-ring on the contacting surface.
• Torque: 10.8 N.m (1.1 kg.m, 8 ft lb)
