Steering noise in my NH Workmaster 35

cgmeyer77 · Aug 13, 2017

I purchased a barely used NH Workmaster 35 (2014) with 180 hours on it and noticed a "growl" in he steering along with a significant vibration in the hydraulic pipes to/from the steering system. One of the pipes had actually cracked. I replaced the pipe, changed the fluid (waiting on a new filter) and the noise is still there. Particularly bad with weight in the loader. I figured it was air in the system and I tried the recommended purge by taking weight off the front axle and turning the wheel all the way left and right with a 5 second hold. Also changed out the gear oil in the front axle, and the engine oil. No luck, still bad vibration noise in those steering hydraulics. Its another cracked pipe withing to happen. Any thoughts/ advice would be appreciated!

Is this 2 wheel drive or front wheel assist? Reason for asking is that in looking at the parts diagrams it shows a separate pump for steering month front wheel assist model but I could not find a separate pump for the 2 wheel drive.

Growling usually indicates that the pump is cavitating or getting air drawn in the inlet. Based on what you are describing I would determine where the pump is and then triple check all the lines on the inlet side of the pump. If there is a filter in the inlet I would suggest using the factory filter since there has been reports of aftermarket filters causing this problem on some models of tractors.

good luck in finding this problem.

It's a four wheel drive with a ram assist on the front end. Not sure where the pump is or if there's a filter on the inlet side but I'll look into it. Thanks for the response!
