PROBLEM
| Hydraulic warm up procedures should always be followed as stated in the machine Operation and Maintenance Manual. Operating a machine prior to completing these procedures can result in a thermal shock condition in cold weather. The existing spool of the stick regeneration valve can stick or seize inside the valve when the hydraulic oil is cold during winter on Excavators. If the existing spool fails, it will cause or result in a drift of the stick, even if the joystick control lever is back into the neutral position. |

ACTION REQUIRED
| The part number of the stick regeneration valve has not changed with the improvement to the valve. The dealer should verify the part number of the existing valve on the machine and order that same part number valve. When the valve is received from parts, ensure that the valve serial number that is stamped on the stick regeneration valve is the latest valve. The serial number of the new valve should be marked with FE0064 - Up or FEH2133 - Up, as outlined in the SEPD1564, Service Magazine, "An Improved Stick Regeneration Valve is Now Used on Certain 336E Excavators". Refer to Image1 for the stick regeneration valve number location. |
