I’m servicing the hydraulic return filter on a Cat 311B, S/N 8GR00401. I don’t know when the last time this filter was serviced. Following the service instructions I have released any pressure in the tank, removed the filter cover and released the pressure in the filter canister. Next you’re supposed to pull in the canister handle and rotate to align the retaining tab with the slot. Sounds easy?! I cannot get the canister to rise despite pulling on the handle. I’ve tried a few light taps to free it up and a gentle pry up on the handle- no luck. Am I missing something or any other tricks to try? Any thoughts @ahart or @Nige ?
