Solenoid Seals

CHECK SOLENOID SEALS
If there is foreign material in the solenoid valve, there will be no fluid control even with solenoid operation.




a. Check No. 1 and No. 2 solenoid valves. (A540E, A540H)
- Applying 5 kg/sq.cm (71 psi, 490 kPa) of compressed air, check that the solenoid valves open do not leak the air.
- When supply battery voltage to the solenoids, check that the solenoid valves open.




b. Check the lock-up solenoid valve. (A540E, A540H)
- Applying 5 kg/sq.cm (71 psi, 490 kPa) of compressed air, check that the solenoid valve opens.
- When supply battery voltage to the solenoid, check that the solenoid valve does not leak the air.




c. Check No. 1 and No. 2 center differential control solenoid valves. (A540H)
- Applying 5 kg/sq.cm (71 psi, 490 kPa) of compressed air, check that the solenoid valves open do not leak the air.
- When supply battery voltage to the solenoids, check that the solenoid valves open.
