Servicing Pulse Width Modulating (PWM) Valve 

 

If an oil leak develops in a PWM valve, there are O-Rings that can be replaced. Tolerances on the valve 
are very close. Any contamination, no matter how small, may cause the valve to malfunction. Follow 
these steps closely to disassemble/clean the valve. 

DO NOT ATTEMPT IN FIELD

 

1. 

Place all controls in NEUTRAL, stop engine, place tractor in PARK, 

remove key.

 

2. 

Clean area near valve. Wipe/use compressed air. 

3. 

Remove valve from planter. Plug all hose connections or wrap tape over 

connections to prevent contamination. 

4. 

Find a clean area to disassemble. Place the valve in a vise or clamp with 

the solenoid (A) in a horizontal position. 

5. 

Lay out a clean cloth to place parts on. 

6. 

Remove Top Cap nut (B), Secondary Cap (C), O-Rings (D), and electric 

solenoid from solenoid valve stem. 

7. 

Using a 1-1/8" wrench, loosen solenoid valve stem (E). 

8. 

Place solenoid valve stem on clean cloth. 

9. 

Using compressed air, blow through valve body cavity. Clean all 

disassembled parts with compressed air. It is not recommended the parts 
be cleaned with solvent. This could make the parts dry & difficult to 
reassemble. 

10. 

Replace damaged O-Rings. 

11. 

Valve reassembly: Using clean hydraulic oil, lubricate valve body cavity 

and piston spool. 

CAREFULLY

 thread spool into valve body. 

12. 

Tighten Valve Stem with 1-1/8” wrench. 

13. 

CAREFULLY 

re-install electric solenoid, O-rings, secondary cap, and 

top cap.  

14. 

Re-install valve on planter, making sure no contamination enters system.
