you need a new accuimilator, located under rear of boom.Can anyone suggest why when fitting or removing hydraulic hose quick couplers on grab I can't release any residual pressure in the system so end up slackening off pipe unions to let pressure go in order to fit or dissconnect ?
Only accumulator I got near the boom are the 2 long 1s on the main lift ramyou need a new accuimilator, located under rear of boom.
Can only be checked with specialist equipment. Not sure on cost of new one but not mega bucks. easy to fit . I think i would just get one and try it.
Theres a few sphere shaped ones under the cab but not under the boom I don’t think. That diagram looks to be under cab and there’s two I can see.
The sphere in the middle of the pic is the brake accumulator
