my dad has an old M-970 that he loves dearly injection pump is dead right now. we found an 853 at what sounds like a good deal 5000 idk what year it is im gonna say 97 or later has an aulim plate that says somthing was revised sept 97 on the back of the cab above the radiator cover. just wondering how reliable is the izuzu 4cly deisel in them? the perkins thats in our 970 is great was rebuilt in mid 90's. this 853 is to use while the 970 is down and will probly remain with us as a backup and for smaller places the 970 cant fit. does anyone know what brand hydrostats are in the 853's weve had good luck out of sunstran thats in the 970. the 853 has 2000 some hours and leaks oil from two triangular shaped holes in the belly pan at the back wondering whats above them for it to leak hydraulic lines?
