The 1076933 Stop may seize in the stick cylinder bore on certain 330B L, 330B LN and 345B Excavators. The root cause has been identified as a burr at the intersection of the stop bore and the inlet hole of the cylinder cap. In case of a burr, the failure happens in very early hours, as it will scratch the stop creating metal chips that will quickly block the stop entirely.

This program is released to check the machines still on stock at the branches. If one of the machines listed here above has been sold and has worked more than 100 hours, it is not necessary to perform the program anymore.
Stop the machine with the stick cylinder rod fully retracted. Release the pressure of the stick cylinder.Disconnect the hose at the stick cylinder cap end side. Insert your finger through the cap inlet hole. Check that the stop is free to rotate on the rod and that there are no heavy scratches on the stop. If the stop is heavily scratched or not free to rotate, replace the complete stick cylinder. All the stick cylinders removed from the machines have to be shipped back to Gosselies (pay attention for not sending them to Reman. Contact Gosselies Product Support to request the issue of a Parts Return Request.
