i do not have any pics of removing the vacuum/power steering pump from the truck
to remove the pumps from the truck, you must disconnect the power steering lines from the gear box, and where the lines connect for the hydro boost brakes.
there is a support bracket that mounts to the block and is connected by one of the power steering nuts. there is an oil feed line that goes into the bottom of the vacuum pump that needs removed also. lastly, remove the two bolts that hold the pump to the timing case. then remove pumps
remove the 4 nuts that hold the power steering pump to the back of the vacuum pump and pull the pumps apart
then you will remove the two bolts holding the vacuum pump together and u will split it apart
start out by removing this piece
from the pump
to do that, take a deep wall socket and knock it out like so
there is a seal inside and an o-ring on the outside that needs to be changed.
to get the inner seal out, use a socket to knock it out like so
now its time to go back together with it. replace the o-ring on the outside. install the inner seal the same way it was removed.
then put a little oil on the seal and o-ring, then reinstall it into the vacuum pump using a socket to knock it into it
replace the o-ring on the gear side of the pump
the mate the two sides back together making sure you line the slot up
do not force it. it will go together easy if everything is line up right. put the two bolts back in and tighten them down.
next you will mate the power steering and vacuum pump together. make sure they are lined up, and spline together all the way. do not force it.
now you reinstall it onto the truck
