Installation Procedure for the Fuel Transfer Kit on the Hydraulic Electronic Unit Injector (HEUI) Pump

Installing the Fuel Transfer Pump onto the HEUI Pump


(1) HEUI pump

(10) 239-2402 Seals

  1. Install the three new 239-2402 Seals (10) on the back face of the HEUI pump (1). Refer to Illustration 4.

(2) Fuel transfer pump

(11) 179-8128 Seal

  1. Install a new 179-8128 Seal (11) on the fuel transfer pump (2). Refer to Illustration 5. Use 1U-6396 O-Ring Assembly Compound in order to hold the seal in place during assembly. Ensure that the seal is completely seated.

  1. Do not remove the temporary bolt. Position the fuel transfer pump on the HEUI pump. Be sure to properly align the drive tang on the fuel transfer pump with the drive slot on the HEUI pump.Note: Align the drive tang of the fuel transfer pump so that the flat end is vertical. Refer to Illustration 5. Align the drive slot in the HEUI pump to a similar vertical orientation by using a flat head screwdriver. Refer to Illustration 6.Note: Once the fuel transfer pump has been placed onto the HEUI pump, ensure that the face of the fuel transfer pump is flush with the face of the HEUI pump. If the pump faces are not flush, verify the alignment of the drive tang.

  1. Install the three mounting bolts (7) for the fuel transfer pump (2). Tighten the bolts to a torque of 6.0 N·m (50 lb in) by using Tooling (A). Start torquing the bolt in the top right corner and go in a clockwise rotation. Do not remove the temporary bolt (9) . Refer to Illustration 7.

 

  1. Install the three tie bolts (8). Tighten the bolts to a snug fit by using Tooling (B). Refer to Illustration 7.

 

  1. Remove the temporary bolt (9) that is located in the upper left hole by using Tooling (C). Install the remaining tie bolt (6) and tighten the tie bolt to a snug fit by using Tooling (B). Refer to Illustration 7.


Tightening sequence for installing the fuel transfer pump

  1. Tighten bolts 1 through 4 in a numerical sequence to a torque of 32 ± 5 N·m (24 ± 4 lb ft) by using Tooling (B). Refer to Illustration 8.

 

  1. Tighten bolts 5 through 7 in a numerical sequence to a torque of 8.0 ± 0.4 N·m (70 ± 3.5 lb in) by using Tooling (A). Refer to Illustration 8.

 

  1. Loosen the bolt at location (7). Torque the bolt at location (7) to 10 ± 1 N·m (90 ± 9 lb in).

 

  1. Loosen the bolt at location (5). Torque the bolt at location (5) to 10 ± 1 N·m (90 ± 9 lb in).

 

  1. Loosen the bolt at location (6). Torque the bolt at location (6) to 10 ± 1 N·m (90 ± 9 lb in).

 

  1. In order to ensure that the gasket completely compresses, repeat Step 7 through Step 11.
