Throttle Pedal (and linkage) problems on 69, PLEASE HELP!

Ok i bought a 69 912 yesterday (I figured i would post this here because NOBODY at all is in the 912 Forum) and it has some serious throttle pedal problems. Sometimes the throttle will stick and other times it won't go all the way down.

I have figured out what the problem is:

The pedal itself is fine and so is the rod that hooks to the pedal. But on the end of the rod that hooks to the pedal there is a small Ball-Cup. This ball cup is so worn out that it keeps falling off of the throttle arm piece.

I need a new one of these ball cups.

The next problem is with the arm that connects to that rod (wuth the bad ball cup) and connects to the MAIN throttle rod. The arm is old and weak and seems to bend from side to side a lot causing it to bind up and get stuck.

I need a new one of these arms.

Ok now I know what I need but I have no idea where to get them. I checked Tweeks.com catalog and they don't list or show either one of the items. Automotion's catalong doesn't show any of them either.

Do any of you know where I could get these parts at? I need them bad because I want to get this baby back on the road!

Thanks

There are over a dozen Porsche dealers that advertise regularly in Excellence, and do a large-volume phone order parts business ... some have web sites, others don't. I have personally dealt with Vasek Polak, Stoddard, Rusnak, and Don McGill, and can recommend any of them. From your description, the part number in my '72-'73 parts catalogue is part no. 900.169.001.02, and for my car, the same part number is used on both the end of the throttle cable and the lever from the pedal, so if a dealer can verify the part number for your car, you may want to order two or three spares!

Ok thats the part number for the ARM right?
I really apriciate your assistance. I am in a very rural area and don't have any Porsche dealers within 200miles.

Could you give me any URLs or phone numbers to any of the people you have dealt with. I havn't subscribed to exellence yet but I plan to very soon. In the meantime I want to get this great car on the road!

Ok I was reading here in pelican's catalog and they don't seem to list the parts I am needing. But they do list 911 Improved Throttle Link for $20 the description says:

Beginning in 1974, Porsche replaced the rubber throttle linkage coupler with one that is surrounded in metal. Over the years, the rubber inside can deteriorate, leaving you with a less than ideal accelerator linkage setup. Replace your old worn out one with a brand new one today.

I have no idea which piece this is talking about. I didn't see any rubber throttle linkage pieces. Where is this piece located and could it solve my problem? Anyone know?

Thanks!

The part number I gave you is just the socket end, it has a female thread that can be attched to the throttle cable, or the rod. The rubber part referred to in the item description on Pelican is molded onto the back side of the accellerator pedal ... the old way to fix it was to buy a new pedal, which I did, because it was worn from contact with my right foot! I haven't replaced it yet, as it isn't worn out completely ... no problems with the throttle linkage, and I intended it as a cosmetic improvement along with new brake and clutch pedal covers, as I finish with carpet renewal. If your pedal is worn like mine, I am not sure if you would want to extend it's life with a new link for the back side.

I am over 215 miles from the nearest dealer, myelf!

Ok I see that Stoddard has the ball cup that i need! Great!

Now does your catalog happen to have the part number for that arm that I need? I really need the part # see if you can find it for me if you don't mind

Once again I really really apriciate your help. I figured I was about to set out on a long journey to find this part but it looks like I won't even have to step outside :P

Thanks again!

Sorry, I misread the pard with the two arms ... brain fade, or dirty glasses, I guess. I doubt if you need a new 'Deflection lever, front' [arm] as it rides in two plastic bushings, which there may not be much left of, after 31+ years ... the bushings part no. is 901.423.253.00, and the washer under the cotter pin may need replacing, too! Just in case you want an arm anyway, the pn is: 901.423.250.02! Just in case you want to have a go at rebuilding the whole pedal cluster ... someday, Stoddard has a set of all of the plastic bushings in a 'kit' ... don't have that part number, though! Good luck!

Ok great! That should be all the numbers I need.

Actually it's that arm that has the problem it for some reason seems weak and wants to bend side to side. I will probably just go ahead and buy a new arm, bushings, washer, etc. that should fix it right up.

Also where can I get a catalog with the part numbers in it like you have but for my 69 912? I'm new to this Porsche stuff. i just switched over from BMW (thank god) thanks for the help!

You'll want to go to:
www.my-porsche.com

They have the manuals and parts catalogs you need. I would suggest you buy what you can for your year/model of Porsche as Porsche is starting to discontinue the manuals. I know--I can't get a few of them for my 911 any more!!

Glad to help! It seems as though us owners of the pre-74 cars need to stick together ... and the Internet seems the best way yet!!!

Many of the 'slick' cover mail-order suppliers have a smattering of factory publications, but NOBODY I have seen lately can match MY-Porsche in Monterey CA, another place I have used and recommend (sometimes I forget some in off-the-cuff lists) at URL: www.my-porsche.com ... they have a great list online! I would recommend the microfiche version, as viewers are available used from ebay and other sources. You can run up a tremendous bill on your credit card very rapidly on factory pubs. and parts catalogs seem so usable in that form ... I guess the VW and Porsche dealers have gotten me used to them over the past 32 years or so! One book for the 912 I can heartily recommend for 912 owners is the Clymer 'Porsche 912 Handbook' ... as it is superb, and features many 'factory' photographs, and includes a photocopy of an entire 912 owner's manual! It puts all other Clymer manuals to shame and any of the Chilton or Haynes manuals, too! I am 99% sure you won't be disappointed.

Ok since you are so thrilled to help me, hehe ! Then do this for me please. Can you also give me the part # for the rod that goes from the back of the pedal to the deflection lever (the one with the ball cup on the end)? That should be the last part number I need. Sorry to bug you again

The 'Pressure Rod' part no. is 901.423.201.01. And, the reason my car's pedal assembly is the same as yours is the same reason so much commonality exists for so many years of VW Beetle production ... something, once refined, wasn't changed until there was a reason for change! In the case of early 911/912 production, there was no reason to the change the pedal cluster until the so-called 'helper spring' was added to the clutch pedal design.

Hmmmm, stoddard doesn't seem to have the pressure rod. It just says "NO DATA FOUND" thats not good hmmmm I guess I'll have to try someone else.

Well I orderd some ball cups, the pressure rod and deflection lever from Stoddard today.

I ended up needing the deflection lever because today when i was fooling around with it trying to figure out why it kept bening the thing just broke. I guess it was just to old.

I am going to order an entire Weltmeister Bronze pedal bushing kit tommorow from Automotion. I am just going to remove the entire pedal cluster and repaint it and put new bushings in.

Has anyone tried these bronze pedal bushings? If so what's your opinion on them?

Thanks!

Hi Guys,

I accidentally fell upon a great catalog that has some great diagrams and information regarding part numbers for our Porsches. If you don't already have it get it from AJ-USA. It's free and very informative.

Best Regards,
