Usage:
All 3300 Series Engines With DI Scroll Fuel Systems Except Japan Built D4E, D5B, And D6D Tractors
Description of Change: New screws, bolts, clamps and bracket assemblies are used in the fuel injection lines groups for the above engines.
The new screws are made of softer material. The new screws will twist off (break) before they can be tightened enough to cause damage to the fuel lines. The screws can be tightened to 2.3 ± 0.2 N·m (20 ± 2 lb in). This torque is not shown in the Service Manual.
The new clamps are made of a thinner metal and are made to hold only two lines together at a time. This makes a more flexible assembly of the fuel lines and clamps. This will decrease the stresses on the fuel lines when they are installed.
Adaptable As: The new parts, when used together, are direct replacements for the former parts as shown in the Chart A. The new parts are in effect with the serial numbers shown in Chart B.
