Fuel Injection Pump.
« on: February 08, 2010, 22:40:31 »
I have the injection pump removed from the engine and whilst cleaning the exterior i was surprised at the ammount of grime and gung coming out of the drive gear end.
If i remove the side and bottom covers to clean the interior are new gaskets still available?
 What other operations would be beneficial before refitting to the engine?

Hello,

With the side cover removed, rotate the pump and watch to make sure all six of the pistons are  moving up and down.  You will also want to make sure that the rack moves freely back and forth and returns to its starting point.

Concerning parts, you will most likely have to go to a Bosch Distributor who has books and part numbers on these seals. One of the injection pump re-builders may also help you out.

How about sending it to Hans and have him put it on the test stand? And when you install it, time it to No six cylinder. Look at the book! You can adjust it using a road test, but it's difficult because of access.

When refiting i would have thought that you would use number one as the reference point(number one being at the front of the vehicle)
