Spare Injection Pump has Super Fast Idle

You should be able to grab that black shaft and pull it left in that picture to move the weights manually. If that does not move, the idle would be free to climb with nothing to govern it.

I suspect that the little slot that the control sleeve uncovers is plugged. I would try spaying some carb cleaner on it. I would pull the timing plug and spray it full of carb cleaner and then put compressed air to it.

The proper way is to take it apart and get all of the varnish out of it.

That collar is on there so tightly anyway... and the only way I had success was to tear it apart.

^ My thoughts also.

I tried again today and was able to get the flyweights out and the sliding sleeve extended. It felt like it was stuck before.

I know I should take this pump apart and clean it but I'm going to put the top back on and try it now as its still on the motor. I am going to take my other pump apart, the one with the wobbly main shaft. I'm clearing a table in the basement to start the process.

Does anybody know where to find the torque specs for the fasteners in these pumps? I've found a few things on the internet including the great Gnarlodious rebuild, but I'm having trouble finding anything further; a diagram with part numbers, specs for reaming the new bushings, etc. If anybody has info they would be willing to share it would be greatly appreciated.

Seen this in the FAQs? Sticky?    http://www.vwdiesel.net/forum/index.php?topic=30340.0

Hi ORCoaster,

Yes, I did see that and it is helpful especially for the sealing kit part numbers. And I'm still reading the Bosch VE manual which has tons of information on the functioning of these pumps. I'm still looking for part numbers for the other pump components (including the accelerator, cold start and idle lever seals), torque specs, and any other info which would help me with this.

Thanks again!

Video looks good. I'd try runnin it.

But I'd also get a seal kit and if the thing runs ok, I'd pull it back out and re-seal it.
