Throttle Shaft Leak Repair - A Question....
« on: February 28, 2010, 04:25:40 pm »
'86 1.6 Jetta with leak around the throttle shaft.  I've removed the *@#&*!* springs and started to push the shaft out through the cover, hoping to see the o-ring.  It seems to be binding a bit on something and I'm not sure how to proceed.  There is some sort of vertical shaft at the rear of the pump with a spring that doesn't let me tip the cover very much to investigate.  Can I remove this?  (What is it anyway?)

Tips, hints, advice, etc. appreciated!

Frank

Is yours a turbo pump?
this is the o-ring

It's a normally aspirated engine.  It sounds like if I remove the vertical shaft on the engine side of the pump that I should be able to remove the cover away from the shaft and access the o-ring.  Does this sound right?  (Thanks for the picture.)

You push the shaft into the cover as you pull the cover away from the pump.
then you can unhook the governor.
it is a fiddly proceedure.

OK thanks - do you know what function the vertical shaft serves?  That seems to be making it hard to tip the cover.  Maybe I just have to try harder....   :D

That thing has the cold start raise the idle linkage on the backside of the pump don't it?  There is a spring and some other stuff in there under the cover if so making it harder to remove.  You can unhook it somehow, can't remember off hand.
Many things we do naturally become difficult only when we try to make them intellectual subjects. It is possible to know so much about a subject that you become ignorant.

I wonder?  The cold start has been disconnected so maybe I don't even need it...   ???

Cold start advance and fast idle are two very different things.
