The throttle shaft pushes right up and out of the upper half of the pump. I can’t seem to find the right oring for it so I grabbed one from my air conditioning assortment. I will use a Bosch oring instead. I just have to wait a day for the parts.
I ordered a new throttle shaft oring and removed my A/C oring by pinching it. It sticks up far enough to be grabbed and removed without any chance of scratching the shaft. Do this technique whenever possible. Make sure the thrust washer is still on the shaft when the final oring is installed.
Using tape to cover the threads and especially the index splines, keeps from gouging the oring during install. Use STP on the oring during install!!!! Insert the shaft back into it’s bore. Don’t add the throttle arms until the Final Assembly.
