Do I have to take the front cover off? It seems like there is something still attached.
Injector pump removal: (from memory, but check the TM. It covers it.)
-Disconnect the batteries
-Disconnect the IP solenoid (pink wire)
-Remove the air cleaner
-Remove the CDR valve assembly (valve, hoses and bracket)
-Disconnect the vacuum pump lines from the pump modulator on the side of the IP
-Remove the intake manifold and injector line clips
-Stuff rags in the intake ports to keep junk from falling into the block
-Remove the intake gaskets and scrape them clean
-Disconnect the injector lines (you'll probably need a crows foot wrench to get at the bottom lines)
-Remove the three bolts that hold the IP to the crankcase. You'll probably need a flex-head ratcheting wrench to get the bottom one on the driver side. $12 at O'Reilly or Lowe's, etc.
-Remove the oil fill tube bracket and pop out the oil fill tube
-Using a big (7/8" I think) socket and breaker bar turn the engine over by hand until the bolts in the oil fill tube opening line up where you can reach them. There are three. It helps to have someone tell you when they're lined up. -Remove them using a magnetic socket. If you drop them into the timing cover you've turned an hour job into a massive project of removing the radiator, alts, and pretty much everything else to get the timing cover off and try to find them before they ruin a bunch of stuff.
-Now you can pull the pump off.
To replace it you just do everything in reverse, but you have to get the pin on the pump to line up with the little hole inside the crankcase/oil fill tube opening. Make take a little jimmying around, and best with 2 people and a good flashlight.
Be sure to put the heavy duty intake gaskets on (they have the metal square in the center hole).
To set the timing, just line up the scribed mark on the pump with the one on the crankcase. Or take it to a diesel shop and pay them $35 to do the timing with their gauges, etc.
Sorry to hear about your glow plugs. Were you able to get the pieces out?
