PROBLEM

Show/hide table

The existing 158-9116 or 226-4149 Stick Cylinder Assembly can be ovalized at the head side on certain 365BL, 365BL Series II and 365CL Excavators. If the existing stick cylinder assembly is ovalized, it will lead to leakage between the head and barrel.

ACTION REQUIRED

Show/hide table

If leakage between head and barrel is noticed, measure the vertical and horizontal bore diameter of the barrel from head end up to +/-20 cm deep. The nominal bore dimension is 200.0+/-0.1mm (7.874 +/- 0.004 inch). If ovalization exceeds this specification, change the cylinder assembly with a new 342-2073 Stick Cylinder Assembly in order to avoid any further leakage. Change the 11 bolts at the head with new 112-1531 Bolts that are made from a higher grade material. Tighten the bolts to a torque of 900+/-100 Nm. Refer to your Disassembly and Assembly Manual (RENR1970 for 365BL and 365BL Series II or RENR8616 for 365CL) Stick Cylinder - Remove / Disassemble / Assemble / Install for procedures.

In the claim description, specify the recorded ovalization. The inspection report attached to the claim is required in order to provide feedback to the Hydraulic Excavator Product Support Group.
