Remove side inspection plates. Hitch a load to 3-pt or raise up and chain down arms. SHUT OFF motor, leave raised, and observe up to the lift cylinder underneath top cover. Look closely and for several minutes. If you see oil seeping down from the piston/ram, the piston and/or cylinder are worn and need replacing. If so, while at it, may want to clean pump chambers and entire system. That may require dropping pump to do a thorough job. If no oil leaking down, try replacing the safety relief valve.
