Dismantling (continued)
8. Remove the Plate (151)
9. If the return springs (221) are weak, the sliding resistance
of the 'O'-ring causes the plugs (211) to stick in the
casing. In this case, remove the plugs with a straight-
headed screwdriver.
Note: Use the groove in the plug periphery, taking care not
to damage the plug. Take care as the plugs may fly out due
to the force in the return springs (221).
10. Remove the pressure reduction assembly return springs
(221) from the casing.
Note: Make a note of the relationship of positions of the
pressure reduction assembly and the hole in the casing to
facilitate reassembly. (When reassembling, install in the same
position as that before disassembly).
11. Loosen and remove the hexagonal socket head bolts
(125) with an Allen wrench.

Questions and answers
Trouble shoot no swing
To troubleshoot a no swing issue on a JCB JS200, follow these steps:
1. Check if engine starts and operates normally:
- If the engine does not start and “Electric system abnormality” is indicated, refer to Trouble No. 10.
- If the engine starts but rotation does not change with throttle, controlling engine rotation may not be possible.
2. Check hydraulic system components:
- Inspect for sufficient hydraulic oil amount; refill if low.
- Check the hydraulic oil strainer for contamination; clean or drain as needed.
- Ensure oil levels in reduction gears are adequate; refill if needed.
3. Check for mechanical or control blockages:
- Inspect the remote control valve for:
- Low secondary pressure due to low primary pressure—apply correct primary pressure.
- Damaged spring—replace the spring.
- Excessive clearance between spools and casing—replace the remote control valve.
4. Inspect motor operation:
- If motor does not run or rotates slowly:
- Check for pressurized oil; inspect pilot piping for damage.
- Remove foreign matter between plunger and body, orifice, or dumper piston and cap.
- Repair or replace damaged parts as needed.
5. Check electrical and wiring connections:
- Inspect battery terminals and alternator wiring for looseness or corrosion; tighten or replace as needed.
These checks cover both hydraulic and electrical causes that could lead to a no swing condition.
