Hydro-Transmission Life Expectancy

[Guest]

While reading the Technical Information pamphlet by Sauer Danfoss I came across the suggested life expectancy of their Series 15 pump/transmissions, which is approximately 1000 hours or 5 years at 200 hrs/yr. Curious as to how many of you are close to that amount.

21 years & over 5000 hrs on a 1984/85 Simplicity Sovereign 7790 Lombardini Diesel.

I am the second owner of a 7012H and although I have not used it much in the 2 years I've had it I know it's well over that, because of the lawn it used to mow, and still going fine.

From what I have read and the many GT's I have owned which were from 25-30 years old, the hydros are almost indestructible as long as the oil and filter are maintained.

In sundstrands case its forever as long as oil/filt are changed and do not tow it without releasing pressure valves,,
