ACTION REQUIRED
Show/hide table
| Replace the leaking lock cylinder, using new seals for the cylinder and the piston. Inspect the piston for damage during the repair. There may be some witness marks on the piston which occur during normal operation. Unless the marks are excessive, the piston does not need to be replaced. This service letter allows for a claim of one sideshift lock cylinder and associated seals per machine, where the failure is due to cylinder porosity only. If there is more than one porous cylinder failure on the machine, please contact Backhoe Loader Support for further assistance.
