Slight knocking occuring (possibly from rear transmission

Resolved Question:

Slight knocking occuring (possibly from rear transmission but very difficult to pin-point) on a Kubota M6040. Related to rotation of rear wheels and occurs once per rotation and at a constant point of rotation. Makes no difference if in gear or free wheeling. This machine has only 450 hrs working time - any ideas? Chris XXXXX, Halifax

Hi Chris and welcome

Sorry for delay.

Normally when you have this type of sound as you already know it's difficult to find.

It usually ends up being a broken tooth on a gear.

This can be from shock load.........or a defect in a gear..... but you can't tell until you disassemble and inspect.
What I do is have a clean drain pan and drain some fluid out of trans and diff and look for metal.
This will at least tell you where the problem is if the rest of drive line checks out good.

I wish there was better news.

Hope this helps find the problem.

Thanks
spanky
