Group 1 - Before Or After Failure, Install Fuel Bypass Valve, Filter Base And Filter
1. Remove 7E6288 or 7W0032 Tube Assembly (1) from the transfer pump to the fuel filter. Remove the 6V8724 Elbow (2) in the fuel filter base. Remove the existing fuel filter base and fuel filter. For earlier engines which have 7W0032 Tube Assembly (1) and 6V8724 Elbow (2) as shown in Illustration 1, the 6V8724 Elbow (3) and 7W7381 Fitting (4) at the governor housing must also be removed, and replaced by a new 7E9898 Connector (6). Take care not to disturb or damage the small check valve in the governor housing under the connector.Later engines with 7E6288 Tube Assembly (1) and connector (6) as shown in Illustration 2 already have the correct connector in the governor housing.
2. Disconnect the fuel return hose and its elbow (5) temporarily.3. Install the new 3E7410 Tee (7) and 5P1046 Connector (8) at the governor as shown in Illustration 3. Install the 5P4924 Elbow (5) into the new tee and connect the fuel return hose back to the elbow.4. Install the new 6I4802 Filter Base, using 7C1159 Gasket. Install 8T0788 Elbow (9) at the fuel filter. Install the new 6I2421 Tube Assembly (10), 6V8774 Tee (11), and 6I2422 Bypass Valve Assembly (12) to 8T0788 Elbow (9) at the fuel filter. Refer to Illustration 3. The 6I2422 Bypass Valve Assembly must be installed exactly as shown in Illustration 3, with Plug (A) directly opposite Tee (11). It is possible to install the valve incorrectly, with Plug (A) up. In that position, the bypass valve is backwards and will not function.
5. Install 5P1046 Connector (13) to bypass valve assembly (12) and 5P1442 Hose (14) to connectors (8) and (13) with 5P4961 Clamps (15) as shown in Illustration 3. Remove existing bolt and mount the bypass hose with 8L5449 Spacer (16), 4K8864 Clip (17), 9M1974 Washer (18), and 6V5219 Bolt (19) on cylinder block cover as shown in View B-B. Check hose routing to make sure they will not be rubbed or cut. Tighten the bolt to 25 7 N m (18 5 lb ft).6. Install new 6I4783 Filter (20). Paint parts after assembly to prevent rust of new valve, fuel line, and other parts. Be sure to inform the customer of the following:a) The new filter will filter out much smaller particles than the former filter in order to protect the fuel injectors from possible wear. For that reason, customers should use only the new 6I4783 Filter. Former filters will not fit the new filter base.b) Fuel filters should be installed DRY and primed with the hand priming pump. Do not
