PROBLEM

A 1899827 Channel needs to be installed on certain 3516B Power Modules. The channel is part of the 1901328 Baffle Group and is used to prevent engine exhaust from re-circulating through the radiator.

Re-circulation inhibits the radiator from realizing its full cooling capability, which is necessary to meet emissions compliance.

Rework Procedure

To carry out this repair, the power module does not need to be disconnected from the power system. However, take all necessary precautions and observe all safety rules as identified in the operations manual.

Turn the control switch to off/reset position and perform other necessary lockouts to prevent the engine from starting.

Open the power module front doors (radiator end).

Measure 72 inches (1829 mm) from the bottom of the door, and make marks on the inside of the door channels. This will locate the bottom of the 1899827 Channel.

Illustration 2: RH Radiator door without channel	Illustration 3: RH Radiator door with channel installed

NOTE: Repeat for both doors. There will be one channel per door.

Partially close the door and verify that this mark is approximately 1 inch (25 mm) below the rubber gasket skirt on the radiator assembly opposite the door. This is to assure that after the installation, the channel will press on the rubber skirt and prevent air recirculation.

Adjust the location of the channel if necessary.

Position the bottom of the channel on the marks and mark the location for the rivet holes matching the existing holes in the 1899827 Channel.

Drill 3/16 inch (4.7625 mm) diameter holes (four per channel).

Attach the channel using four 4D6716 Rivets

Clean any metal shavings from painted surfaces.

Place the power module back into operational mode.
