Cat^® Reman will begin using a machining process on the spring face of the injector body.

The machining process will remove material and a washer (spring seat) will be added to retain the original tappet spring pre-load specification. Refer to Illustrations 1 and 2 for the placement of the washer.

This change will not alter fit, function, or performance in any way.
