INJECTION PUMP REMOVAL WITH LINES DISCONNECTED

MODELS AFFECTED: 1982 V-8 And V-6 Diesel Engines

Page 6C5-8 of the 1982 Regal, LeSabre, Electra and Riviera Chassis Service Manual describes the procedure for removal and installation of the diesel (VIN N & V) injection pump with lines attached.

It has been found that the injection pump alone can be removed and installed with the lines left on the nozzles. For removal, proceed to step 7 without making any changes in the procedure but now continue as given below:

8. Disconnect the injection line clamps that are closest to the pump.

9. Disconnect the injection lines from the pump and cap all openings. Carefully reposition the lines to gain enough clearance for pump removal.

10. On the V-8, remove 3 nuts retaining injection pump, using Tool J-26987. On the V-6, remove the 2 bolts retaining the injection pump.

11. Remove the pump and discard the pump to adapter "O" ring.

The changes in the installation procedure are:

Step 2 - the protective caps remain on until step 4.

Step 4 - Remove the caps from the openings and connect the injection lines to the pump. Install the disconnected injection line clamps (Figure 6C5-14, 1982 Regal, LeSabre, Electra and Riviera Chassis Service Manual).

They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.
