PROBLEM

| The existing loader pilot valve can become inoperative on certain 420E, 430E, 432E, 434E, 442E and 444E Backhoe Loaders. If the existing 267-2760 Loader Pilot Valve fails, the operator will be unable to actuate the lift and tilt functions of the loader.

| In Order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 3% of dealership population. This is an inital order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer. | ||
ACTION REQUIRED
Show/hide table
| If the actuators are no longer aligned with the plungers in the pilot valve, replace the pilot valve. When re-installing the control handle to the pilot valve, use a back-up wrench to prevent over-tightening. The jamnut for the control handle uses loctite and should be tightened to a torque of 40 Nm. |
