Hydraulic pressure

[Andy]

Hi
Our 1996 JCB 3CX Sitemaster is suffering hydraulic pressure loss when demanding full pull on the sticks and stalling pressure completely.
When you gently apply pressure the machine works slowly but gingerly.
This affects both front and rear buckets.
We suspected the hydraulic tank filler cap may have been to blame but we have changed this for a new one and no change.
Any suggestions.

It could be the hydraulic pump, filters or fluid levels. Thorough inspection of those parts would be a great start to diagnose the problem. If you're not really sure how to do that, contact a good mechanic that'll solve the issue.

Thank you for that.
We will check the filters first and go from there.

Thank you for your time.

Did you try adjusting the relief valve pressure? Should be around 320-350 bar afaik.
