Pearl, Pearl, I have a Cat forklift T40 D. It has a #601

Customer Question

JA: What is the complete model and serial number of your machine?
Customer: Pearl, I have a Cat forklift T40 D. It has a #601 type 1 master cylinder in it. but cant find out what fluid it uses.
JA: Are you fixing this yourself? What have you tried so far?
Customer: Yes , I am working on it myself. The brakes went out and I see it has lost all the brake fluid, but I don't know what it uses. I don't think it uses DOT brake fluid.
JA: Anything else you want the equipment mechanic to know before I connect you?
Customer: No, just what type of fluid Cat uses on that forklift

Hi my name is***** will be glad to help. Any of the non brake fluid systems use mineral oil or 10W hydraulic fluid when mineral oil is not available. When I was at the dealer I can assure you we never bought mineral oil.... AW32 10W hydraulic oil is all you need.
