Hi
I have a 1998 4100 HST.
In Nov 2006 I had to replace the charge pump (parts on service bill AM879432, AM879433, AM880337, CH10568), Trans/Hyd oil & filter (LVU800097) after 720hrs. The problem started out as the power steering would be hard to turn and got easier as the tractor ran (warmed up). Then got to a point where it was always hard to turn. The dealer said the high pressure or charge pump was gone.
Well now in Jan 2009 and at 939hrs the problem is surfacing again. I do not believe the pump should go this soon with normal wear. Does anyone know of anything that maybe contributing to these failures? All oils are changed as recommended and always kept up. I have also notice now that while snow plowing you get a hot hydraulic oil smell.
Thanks for any suggestions.
