The 1" is to large, the 15/16 too small. The grip area is so small I can't get a cresent wrench on it. Anyone with information or suggestions... I have been trying to get my speedo to work. I have tested everything and it appears that the speedo driven gear is not holding the cable. | | | | | Joined: Jun 2009 Posts: 2,201 Shop Shark | | Shop Shark Joined: Jun 2009 Posts: 2,201 | year, make and model information might generate some responses. | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | A thin wall socket will get it. I believe it is 1 1/16 or 1 1/8.

I agree with 53monster... we can't help you if we do not know what you are talking about... cuz we don't know everything like Wrenchbender Ret.(that's a compliment, he's the best!). -W | | | | | Joined: Jul 2009 Posts: 49 New Guy | | New Guy Joined: Jul 2009 Posts: 49 | Sorry about that... I did get the gear out. It was 15/16 thin walled socket. I cleaned it up and it still appears to not hold the speedo cable. I don't know how to test to see if the gear is turning when the truck is moving.... i don't want to win a Darwin award for riding under the truck. Are there different size cables? This is a 4 speed tranny I put in my 50 chevy. The tranny came out of my 49 parts truck. | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | When my head gets back to it's normal size after the complement I will tell how to test it. Jack up one or both rear wheels. Put a piece of an old speedo cable or small screwdriver in the hole in the gear. Turn the driveshaft & watch the inserted tool to see if it turns. Put a little resistance on it in case it slips under load.
