A squeeling noise started today on my 8050 ps when I pulled out from a stop sign in 1st high pulling my dozer on a trailer. It stoped when I stoped. Started again when I went forward. Changed to low range and does the same thing. It is a hell of a squeel. Any ideas?

Fan belt slipping,turbo whistle, Intake manifold gasket pushed out?I'm not sure if you need to be moving,or just have the engine under a load.I've seen the manifold gasket pushed out on several units.I'm not sure that I would describe that noise as a squeal,but it deffinately makes an obvious noise as the turbo boost builds up.Usually the gasket fails towards the rear of the manifold above the stater.Hope this helps.

If it happens when applying/using power, I would agree with Lynn on the intake gasket blowing. Mine blew this winter at the back of the intake over the starter and when accelerating would squeal loudly. It was louder in the cab than outside.

Good luck.

Could it be front wheel bearings need repacked(unless it is a FWA)? MACK
