PTO Vibration
Posted: Wed Sep 20, 2017 3:35 pm
When I first got my tractor the PTO was tested for operation and found to be working. Due to the condition of the tractor is wasnt run for long only to check for operation. Whilst I had the hydraulic top off for refurbishment everything was checked inside the casing and nothing untoward was found. The clutch pedal/PTO selector shaft was badly worn and was replaced. When it was removed the PTO selector fork was found to be badly damaged and half of it missing. It looks like it had been rubbing on something as well but all I could see that it comes in contact with is the PTO selector sleeve which in operation this would obviously spin.See Pics attached. No metallic parts were found inside the casing. Having replaced the selector fork with a good one I now find that when the PTO is in operation there is a lot of vibration through the selector handle. No vibration when it is not in operation. Is this normal?? Is there anything in the casing that the selector fork can come in contact with when the PTO is in operation apart from the PTO selector sleeve. Im not wanting to wear the selector fork. Any advice is appreciated.
