I have a 329D with 2400 hours with newer tracks and sprockets (when I bought it ). When I put in high speed and drive about 1/2 throttle it gets a real big vibration, I feel are coming from the tracks. If I drive wide open, it goes away. Is this normal for these machines?
I hate to be a smart a**, but don't drive at half throttle. Whether it has a detrimental effect on your machine or not to run them at half throttle, I firmly believe skid steers/CTL's should always be run at full throttle. Are you sure it is the tracks? Usually a track issue is all the time. How about if you drive over asphalt, does the machine seem to hop? Other than the obvious like rocks/dirt jammed into the tracks, bad idlers or rollers or loose sprocket, it is most likely your tracks.
When on uneven ground it's hard to power thru and run WOT, however I hear what you're saying. The tracks are new but I realize they could still have an issue. I've not ran it on dry asphalt I can give that a try, the sprockets were replaced with the tracks, I can check the bolts make sure they've not come loose. All the rollers seem ok thanks for the ideas.
