All fluid levels (inc the chaincases) are correct I take it..?
Are you using the hydraulics when driving? If not that rules that out.
Can you get it up on blocks and run it with the wheels off the ground..? You may need an assistant to walk round the machine to identify where the noise is coming from. Try doing that with and without the engine compartment door open and see if it makes any difference.

Good point. One assumes that the basics have been checked but often to assume makes an ASS out of U and ME ................

The only reason that I mention the obvious is that we have a 287C that slips the belt a bit when first started. We have tightened it, but for some reason it still slips. As soon as it quits squealing, usually about 30 seconds or less, we can turn on lights and heater etc. and it never does it again that day. It has done this almost since it was new. When we get it into the shop this winter I think we will change belts and look at the alternator pulley.
On that note, has anybody had luck using belt dressing?

No warranty left on it
Dang it.
Only if you have a flat leather belt on a wood pulley. No belt makers tell you to use the stuff.
