Again, thanks! | | | | Joined: Nov 2006 Posts: 125 Wrench Fetcher | | Wrench Fetcher Joined: Nov 2006 Posts: 125 | I am about done cleaning the distributor and now that I am about to put it back together, I was wondering where I can get the pin for the drive gear. Are they pretty common items at auto parts stores such as Napa or Autozone or are they more common at hardware stores. I will also need a new one for the pinion unless a new pin comes with the 3.55 gear set from Patrick's. Does anybody know something about this? thanks | | | | | Joined: Jul 2004 Posts: 5,708 'Bolter | | 'Bolter Joined: Jul 2004 Posts: 5,708 | justin squire,
The pin that goes into the distributor drive gear should be available at a auto parts store or a hardware store.
The are commonly referred to a spring pins or roll pins. If I remember correctly, the type in your distributor was a "coiled" type...hard to find locally. I'm pretty sure a standard slotted spring pin would work fine.
They come in standard diameters, and using the hole through the gear, or through the shaft, it should be apparent what size is required.
Remember that the pin is naturally oversize and will 'mic' strangely. The fit should be a 'hammer' fit...not loose. If you go this route, be sure to cushion the gear in a wood cradle or something so you don't bust a tooth or bend the shaft.
Using a longer pin is fine. A small cutoff wheel or grinder can trim it to proper fit after being installed. Make sure you put the gear back on properly..not upside down! Good luck

It screws in & hopefully <pray a lot> comes out in one piece. You may want to get the installation kit to go with the ring & pinion set. They say money can't buy happiness. It can buy old Chevy trucks though.

Normally it is inside the torque tube, but I have the driveshaft removed from the torque tube and I have already used a hammer and a punch to remove the old pin and release the pinion assembly from the slotted driveshaft. I just need to know if there is a new pin included with the ring and pinion gear set. | | | | | Joined: Mar 2004 Posts: 874 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 874 | That's the propeller shaft coupling pin/rivet. I don't know if one comes with the Patrick's kit...why don't you call and ask 'em? If it doesn't come with the kit, you can get a new one from Obsolete Chevrolet Parts Co. | | | | | Joined: Mar 2004 Posts: 874 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 874 | Click here , select search for part number in upper left hand corner and enter part number 3657332 then click search. For some reason, I couldn't link right to the page with the pin on it. The cool thing about these guys is that they use the original GM part numbers for a lot of their parts and also reference the original diagrams in the catalog. | | |
