Hi Guys just wondering if cab vibration at about 2300-2500 RPM with a 3720 is normal? I just don't remember hearing as much vibration sounds like it might be coming from the cieling or maybe just the hood vibrating behind the dash. Not sure yet but seems like more then I ever noticed before. I am going to check the cab/rop bolts this week for proper torgue just wondering if any other 3000 cab series owners have noticed excessive vibration noise in the cab at higher rpm and if there was a solution?

Thanks all

I have a new 3520 cab and i am real **** and have ocdwith this machine. I dont know about vibration but I will fire it up tomorrow and check that range of rpm for you and report back. Is this with the pto off? I had a rattling noise that was bothering me about the same range of rpm. I did some poking around and took the rear tires off and found it was a hydraulic line rubbing on a bolt so i put a piece of rubber between it to get rid of the vibe. Do you think the vibration was always there and your just noticing it now? or did it just start and your positive about that?

No it was not always there not like it is now, I am going to investigate further keep me posted. we just put on the scv front end loader kit so some lines were retied tighter to the frame this might be something to look at!
