[QUOTE="oldandrusty, post: 122077, member: 22365"] I am new but have gotten really good intel from other equipment forums as it seems most true mechanics are hard to find anymore. With that in mind, I have a 4835 with about 1300 hours on it and now it has started something I can't figure out and the dealer isn't too sure where to start either. Every so often, like the other day, I'll start it to warm it up and all of a sudden the engines comes under what I would consider the response to a heavy load and smokes a bit and powers down for a little bit then will return to normal idle and may do it several times. I thought maybe it was just cold but it is kept inside in heated space. It hadn't done it for several weeks. I did what I needed to do with no problems and everything was fully warmed up and as I was getting ready to put it back in the shop it did it again, several times, just sitting and idling. My question is could a relief or bypass valve in the main hydraulic pump be causing this. It sounds and acts just like they do when you have cylinders fully extended or contracted and the bypass has to kick in when you reach the end of your stroke. The shop foreman said, could be, maybe blower, etc. Don't think it's the blower as it would be more consistent and I would think noisy. Thanks in advance. [/QUOTE]
