Oil & Fuel My little fella is sick.....

[humph]

Hi my smallest tractor a B1700 HST bought new in 1999, just 450 hours, has developed a nasty noise. In Hi only, 2 or 4 WD, There is an intermittent racket which sounds like a small airhorn. This tends to happen most often under little load on the level. Certainly when there is some engine breaking. It is not steering related. Closer inspection revealed a very loose prop shaft which looks like a big job to remove. I also suspected the hydraulic oil, and have changed filters, but cannot find SUDT here in France. Worse still the tractor shares some implements with a brand new L5740 which has separate HST & hydraulic systems, and therefore perhaps different oils in each.

I am worried about cross contamination, and what to use in place of SUDT (The French only sell "Huile hydraulic R45"). I would like to know of a diagnosed racket in other B1700HSTs.

Any suggestions would be appreciated.....

Wish I could help, but I am not a mechanic. I can say that I have not used SUDT when changing in any of my tractors to date, my dealer doesn't even carry SUDT or SUDTII. I used other fluids in both our BX's and L5030.

I had an intermittent noise that sounded bad while traveling in high gears. I thought I had a bad bearing in the tranny or front end. It turned out to be the seal on the front driveshaft cover squealing. Slid the cover up (away from the front differential), cleaned and greased the shaft and seal, and no more problem. Maybe yours has the same problem?

I had a guy drop off a tractor to me a few weeks ago with a bad noise in it. His only happened when the PTO was on. After inspecting it I found the problem to be in the outer PTO shaft cover that was never greased. I greased it and the noise was gone. Cheap fix but it sure sounded awful.
