im looking for some information on testing hydraulic preassure on a cat 311 excavator and what set of gauges to buy looks like the most common ones i see are vevor with multiple hoses and gauges do i need all of that for just one machine
Post a Serial Number and I can look up the Testing & Adjusting procedure for the implement hydraulic system. That will give you a rundown of all the required test equipment - according to the factory anyway.
