(1 - Rework Procedure - Group 1)(2 - Rework Procedure - Group 2)(3 - Rework Procedure - Group 3)(4 - Rework Procedure - Group 4)Rework Procedure - Group 1
1. Clean and pre-paint the new 6I0349 and 6I0350 Fuel Line Groups in your shop before proceeding to the job site. If the engine to be reworked is non-aftercooled, also clean and pre-paint the new 6I0348 Bracket Assembly.
A. Tape off the number 3, 5, and 6 fuel lines in the area of the tower clamp. (See Illustration 1, Section C-C).
Illustration 1B. Make sure that the formed damper clamp for the number 4 and 6 fuel lines is close to the correct position and tape the fuel lines on each side of the damper clamp. (See Illustration 1, Section B-B).C Install 5F2807 Plastic Caps and 2F2990 Plastic Plugs on the ends of the fuel lines.D Clean and paint the fuel line groups. If applicable, clean and pre-paint the 6I0348 Bracker Assembly.E After drying completely, remove the tape. Do not remove the plastic caps and plugs until the fuel lines are ready to be installed on the engine.2. Remove all the mounting bolts from the fuel line brackets at the aftercooler housing on DITA Engines or at the 9Y1112 Bracket Assembly on DIT Engines. Except for the tower clamp assembly, new mounting bolts and washers will be used. Keep the 9X6458 Washers, they may be needed as spacers. The 9Y1112 Bracket Assembly is the large bracket on DIT (non-aftercooled) Engines used to support the fuel line brackets. This bracket is part of the 6N5140 Fastener Group.
If the vee brackets used between the left and right side lines groups on Caterpillar vehicular applications have been previously installed, remove them. Do not reuse these vee brackets. A new clamping arrangement is used on the new 6I0349 and 6I0350 Lines Groups on 3412 Generator Set Industrial, and Marine Engines.
3. Disassemble the tower clamp assembly behind the fuel injection pump. The 9Y3356 Clamp and 9Y3359 Clamp Assembly that form the tower clamp will be reused. (See Section C-C in Illustration 2).
Illustration 24. Disconnect all the fuel line nuts at the fuel injection pump and at the adapters in the valve cover bases.5. Remove the left side and right side fuel lines and clamps as separate assemblies.
