Question: I have a International Case 235 Hydro 4wd tractor, (compact) w/front end loader 1988 model under 700 hours on it,, I know that's crazy low. I purchased it form an estate, the one owner treated it with kids gloves. Anyhow, I've had the tractor 8 months or so, and have discovered that when in the high side of the transmission, going forward only (under load) it makes a clunk sound. Not in time with the rotation of the tire, just random and obvious. I have changed the hydraulic fluid, filter and cleaned the screen. Not finding anything abnormal in the oil.
There was some metallic looking dust in the pan after draining but from what I have read, that's normal for the compact tractors due to factory flushing not being done.
Anyway, all the work I do with it Im always in low and there it works perfect. Please give me your thoughts.
