Hello. I have been using this forum for about a year for information. Many owners are very helpful. I finally joined because I now own a 1969 Stingray that runs great. 4 speed, 350 cu. in./300 HP bought from the second owner with a 1972 title!
My first question is he gave me anew tach cable because the tach stopped working several years ago. This would seem to be an easy fix but I do not want to screw anything up. Any tips? Thanks

Yes this is a fairly easy repair. You need to follow the old cable up to the back of the tach where there is a clip spring that needs to be pushed in (towards the tach) to free the cable from the tach. Remove the old cable from the tach and fish the old cable out through the firewall. Take care to see how the old cable was routed so you can install the new one in the same manner. The new cable will need to be pushed up against back of the tach until you can feel the clip secure itself against the cable.

I would check to see if it is the cable first. These cars have a habit of chewing up the tach gears in the distributer. Pull the cable off the dist end and spin it and have someone watch the tach. If it moves the problem is in the dist. If not you just replace the cable and away you go. If it is in the dist you have to remove it and replace the gears inside.

Most likely it is the cross gear in the distribtor like the previous post. The driven gear will SOMETIMES fix the problem. Sometimes the gear on the distributor is also bad, The distributor is a Corvette only item. There are some replacement shafts with a new gear on them but it requires removing the distributor to fix it. Not that difficult, but you do have to re-time the engine.

Hiyas redchev I'ver replaced the distributor shaft and it's not that big a project. Do a search of archives and other sites to gain knowledge if you need it. Make sure you shim the end correctly to eliminate gap. Also, make sure the dimples are oriented correctly or you won't be able to time it right. All of this information is readily available here. Good luck!

Welcome!!!! I have a 69 also---check on the angle of the tach cable sometimes they take a nasty bend--check out Lars for info on moving your distributor so your cable goes in straight instead of the bend...good luck.
