Need to check accumulator pressures for ride control. RHN03474 10K Hours No suspension action when engaged. Is the charge adapter a 1S8938? What charge pressure goes on each vertical accumulator? What are the horizontal accumulators under cab for?
Accumulators are for brakes, pilot hydraulic system (dead stick lower), & ride control. Do you have 4 accumulators mounted vertically in a group in the front frame.? There are two different options for adapters depending on what thread is on the valve on the accumulator. It will also require an extension because the adapter alone will not reach to the charging valve. See the attached procedure.
