Hi, have a Hyundai HL 740-3 with ride control that needs the Hydac piston accumulator resealed. Would anyone know what pressure the accumulator needs to be recharged to? It doesn't say on the tube of the accumulator or in the service manual.
Don't have a Hyundai spec, but other ones I have done are around 200-270psi. Case tells you to set the ride control accumulator pressure to application. Lower pressure if roading with empty bucket, higher pressure if more loaded traveling. Piston accumulators always seem to leak out the nitrogen, so you will probably have to re-charge again next year.
