Throttle Body Rebuild Service, Who has experience/recommendations? Options

[Van B]

So, now that my 1.8L is running happy again, I’m able to notice small issues. Today I noticed that my throttle body appears to have some wear inside it. Idle was a little high and when I pushed on the linkage arm, it returned to normal.

So, I think a full rebuild is in order. And if it happens to come out a little larger, we that wouldn’t bother me a bit. (IMG:style_emoticons/default/shades.gif)

Who would you recommend to make my throttle better than new?

914 World,
Phil is out of the Throttle Body game. I finally got a response from him today, see below:

"Good morning Van,



Thank you very much for your interest in my re-machined throttle bodies however as of February of this year I am no longer providing this service and I apologize for the late reply. A word of advice, some of the people offering rebuilding services are just re-bushing the worn areas where the throttle shaft passes through the main housing, this will not cure the problem, try and find a rebuilder that will install bearings and seals and provide a positive vertical locking feature for the throttle shaft. Good luck in your search for a quality rebuilder.



Regards

Phil"

I cannot help but feel this comment was directed at me. I don't criticize others work and it would be unfair fore someone that does not know me, my business or has seen my work to criticize my efforts.

914 is a hobby for me and not a business. I do have a full service machine shop including lathes, manual milling machines CNC milling machines etc. Id make parts and repairs on many aspects for the 914. I had a really bad throttle body so I naturally repaired it. I went to the effort of making fixtures to do this in a precise and repeatable manner. I rebuilt several for friends and I decided to make this available to others here. I have rebuilt quite a few without complaints.

I do a basic cleaning and I precisely bore out the TB throttle shaft. I install bronze bushings and ream them for smooth operation. I replace any seals. The actuator arm and the spring are cleaned. I do not plate them simply because of the volume of these that I do. I do replace the nut and washer so in the end, it is a nice looking part. Occasionally I have needed to bore out the large diameter as it can happen that a groove gets worn into the surface. I also can make the throttle plate. As a machinist, this is easy for me to do. I should note here that the plate is not a round disk. It is a special operation needed to properly create one.
I plan on offering the service with plated parts and larger openings for those wanting a larger bore.

Hello Mark,

What's the typical turnaround time to rebuild one of these units?

Thanks,
Chris

Hi Chris

That depends on my regular work schedule. Currently I am open. I can turn around in a couple of days
