    Hello, I have a caterpillar 953a

    Thank you for all the info , the hydrostat system looks like it is air cooled and the cooler is mounted next to the radiator. It’s definitely looking like a very expensive fix for sure

    Hello, I have a caterpillar 953a

    Yes, I replaced all the exhaust. I can’t find anywhere that will say what type of oil the hydrostat uses though?

    Hello, I have a caterpillar 953a

    Thank you, the radiator is in really bad shape I pressure washed it and it still runs hot so I bit the bullet and ordered a new one , I’m hoping that after the radiator change and changing the hydro oil with getting samples taking it will improve

    Hello, I have a caterpillar 953a

    There is a gauge at the hottest it’s showing around 130 ,the actual engine radiator it’s the one that after awhile of running the temp gets up to 230 then I idle down and let it cool off once it cools off it tracks at normal speed

    Hello, I have a caterpillar 953a

    I’m having problems with my older 953 , the machine runs fine while warming up but it starts overheating and then slows down I changed the hydrostat filter 4 months ago with maybe 200 hours on filter pulled it today and it’s as black as can be ! Any suggestions would really be appreciated Thanks
