chain tightness and drive fluid

[sgmike]

I Have An Old 1852 Chopper That Has A New 25 Hp Kohler On It And Was Told To Use 30 Weight Oil In The Hydro's INSTEAD OF HYDRAULIC FLUID. I Was Also Told That The Shorter Drive Chain Shold Be As Loose As Posible And The Long Drive Chain As Tight As Possible. Can Anyone Help?

Yes your Eaton hydrostat units take 30W motor oil.The chains should have a little deflection in them(if you tighten too much you will break chains and wear out sprockets). ;)
