Reference: Service Magazine; August 21, 1989; Page 9; Lube System Screen Assembly Available For Use During Dynamometer Testing," on 3500 Family Of Engines; D11N, 776B Tractors; 777B, 785, 789 Trucks.
The 2W1054 Screen Assembly, referred to in the reference article, must be modified to be used when dynamometer testing. Without the modification, the bail on the screen assembly is too long and will not allow the plug to be installed when the screen is in place. The bail should be shortened to the dimension shown on the illustration.
