****Parts Stock ****

Remove all 298-4478 Relief Valve Groups from dealer parts stock.

****Affected Product****

Show/hide table

After relieving the pressure in the hydraulic system, locate the medium pressure valve. On most models it is located on the frame directly across from the access door behind the cab. The relief valve is located on the top side of the stacked valve without any solenoids attached (refer to Images 1 and 2). The relief valve is below the raised plug. Remove the plug and the valve. Replace the relief valve with the 315-0489 Relief Valve Group. Tighten the plug to 30Nm. Start the machine and check for leaks. Adjust the pressure to the specified 17500 + 1000 kPa (2540 + 150 psi) for standard machines and 19000 + 1000 kPa (2755 + 150 psi) for hydraulic cab riser models.
