Guest mikes48pont Posted November 21, 2009 Share Posted November 21, 2009 I recently purchased a distributor breaker plate for my Pontiac. When it arrived it was the replacement for the original ball bearing plate that my Pontiac has. It seems to use a molded bearing rather than the original ball bearings. The flanges that stick up are flat rather than cradled (like my orignal one) to hold a ball bearing. Question: does anyone know where I can find the molded bearings that fit into the ball track on my distributor? Are there other Pontiac distributors that use this design?Thanks,Mike Link to comment Share on other sites More sharing options...
Guest mikes48pont Posted November 22, 2009 Share Posted November 22, 2009 I found a distributor from a '39 Pontiac which seems to fit and has the molded bearings. We'll see what happensMike Link to comment Share on other sites More sharing options...
Guest Fitz Posted November 22, 2009 Share Posted November 22, 2009 can you post a picture of the differences?In the shop manual (if you have it) the dist. number is indicated, it maybe not the good one you had in your engine.Now you maybe found the right one.good luck.Fitz.

Guest mikes48pont Posted November 28, 2009 Share Posted November 28, 2009 The molded bearings from the '39 work great in my distributor. It's running real well. Now to figure out why I don't have brake lights. How do you post photos?Mike Link to comment Share on other sites More sharing options...
Guest Fitz Posted November 29, 2009 Share Posted November 29, 2009 for photos, I think you have to hit the "manage attachments" button , after look for picture in you PC.You will have to reduce (maybe) the size of your picture if they are to heavy.Fitz.

Guest mikes48pont Posted December 14, 2009 Share Posted December 14, 2009 The images of the ball bearing and molded bearings are attachedMike Link to comment Share on other sites More sharing options...
Guest Fitz Posted December 21, 2009 Share Posted December 21, 2009 They look like identical to me, but I know they are not. Could you show me, or explain to me the differences I can't see.Fitz. Link to comment Share on other sites More sharing options...
Guest mikes48pont Posted December 21, 2009 Share Posted December 21, 2009 Hi Fritz,Yes, it's hard to see the difference. The one on the left is the ball bearing type. There are bearings at 12 o'clock and one at 8 o'clock. The one at 4 o'clock is missing and that's why I had to replace the breaker plate.The photo on the right is the molded type bearing and you can see one installed at the top left and one at the bottom and there is one more that I hadn't installed when I took the photo.With the new breaker plate and molded bearings the car is running fine now.Well, I say that but about 10 years ago I installed an Edmunds dual intake manifold and then parked the car. Now that I am getting it running again I'm finding I have an exhaust leak underneath the the manifold that I have to figure out how to plug up.

Guest Fitz Posted December 21, 2009 Share Posted December 21, 2009 thank you for the explanation.For your exhaust leak, the exhaust manifold are prone to break mostly at the same place, at the 90degree angle under the intake heat riser box. Or beside the gasket between the intake and exhaust. It's the same for you?I had success with a welded repair. Fitz. Link to comment Share on other sites More sharing options...
