Service Magazine SEPD0674, September 2002, "New Pins for the Dozer Blade are Now Greased". Disregard this article. See the replacement article that follows.

Description of Change: A new mounting pin assembly is used on the machines that are listed. The new pin assembly is greased. The new greased pin assembly improves service life.

Adaptable To: The new pin assembly was effective with 824G Series II (S/N: AWW366-UP) Wheel Dozers, 826G Series II (S/N: AYH511-UP) and 826H AWF257-UP Landfill Compactors. The new pin assembly is adaptable to first production of the machines that are listed.

Note: Some machines near the serial number breaks may be equipped with the new pin or the accompanying bearing. The new pin is identified by the use of a grease fitting. The new bearing is identified by a grease groove. The bearing does not need to be replaced if the machine has the new bearing with the old pin.
