Hi working on an early 321c escuvator. The swing will not rotate from straight ahead setting . Hydraulics load up when trying to swing suspect the lock solenoid, but unable to locate the solinoid location. Please can someone advise me on the location thanks Dave

    Sorry that doesn't match any 320C Serial Number I can find, neither does it appear in the S/N Index. Could you post a photo of the S/N plate please.?
