I have my injection pump off and have to replace the bracket. Is it true the vacuum and power steering pumps can be removed when the vp is also out? I’m worried about timing gears falling out of place

 

 thanks 

The VP44 is connected and timed off of the camshaft gear.  The vacuum pump is connected to the camshaft gear, but not timed.

 

There is no connection between the VP44 gear and the vacuum pump gear.  You should be okay to remove the vacuum pump / power steering assembly.

Thank you, John. The graphic is very helpful too

Since I have never done what you are describing before, I would listen to hear if the VP44 gear dropped just a little as you remove the vacuum pump.  The VP44 gear may have been resting on the vacuum pump gear.  The VP44 gear should still remain timed, but you may have to lift the gear a tad when you re-insert the vacuum pump.  Just speculation.  More than likely the VP44 gear will be resting on a shoulder inside the case rather than the vacuum pump gear.

 

I would rather approach this cautiously.

I had to take them both out a couple times so I could get the updated vp bracket set right. Neither of the gears came out of place or anything so I think it’s safe to say it’s fine to do that. 
 

i was concerned about opening a can of worms but it all went well. Thanks again I appreciate your input

I understand why you would have been concerned.  Sounds like everything went well.  You will know everything is fine when that engine clatters to life and there is not a pool of oil on the floor.
