Engine/Transmission (1994 - 1998) Plunger/Barrels

[ColbyG]

I just got my new plungers and barrels in the mail and was wondering if anybody knew the procedure to replace them. I know it is pretty much a complete rebuild but I want to give it a shot before I breakdown and pay close to $1000. I'll keep that as my last resort. If any body could help me with what I need to remove, it would be great. I've already got the back of the pump and throttle assembly removed.

This is not a procedure that you can do at home. You need special tools and calibration equipment. The plungers are attached to roller lifters with very strong springs that hold the lifters to the camshaft. Special tools are used to replace the plungers and barrels. After that is done, the fueling has to be calibrated so each cylinder gets the same amount of fuel for a smooth idle, and generally smooth running. Get a good, authorized Bosch injection pump shop to install the parts for you.

Good luck getting a shop to install the parts that they did not supply and expect a warranty.
