strange sound

[Chilliwack Murray]

The sound at 1:50 sounds very similar to what my 7510 does in high range when I travel at high speed, loaded or unloaded. It does this at fairly low speeds when cold and only near max speed when hot so I assumed it was a relief valve dumping.

I got my machine with 96 hours on it and it has always done it so I didn’t give it too much thought. I’m just about to do a 300 hour service now and wonder if it will change the sound with new fluid and filters. Since yours didn’t make this sound before it has caught my interest as well.

Were you in 4WD? I had similar sound on my BX23D, the plastic boot that covers the U joint at the front axle came loose and would occasionally rub the front driveshaft.

Double check your entire driveline to make sure theres nothing that can rub the drive shaft(s) at all angles.

Check the oil level in the front axle, could be low and the down angle makes it lower.
