Speedo, and an Odd Options

[kkid]

Hey guys,

So my Creamsicle has finally seen a road after about 1.5 year of jack stands time. (IMG:style_emoticons/default/cheer.gif) Now the speedo didn't work so I changed the cable.

I see other cars passing by like a rocket while going at 65pmh so the speedo needle is way off??? I will check this with a GPS today.

Anyways, the odometer is not working at all. This is a bigger problem. (IMG:style_emoticons/default/sad.gif)

Has anyone encountered the same and succeeded to repair??? The speedo works(barely) but odo does not.

Let me know.

Thanks,

I better point out that pointer 2 only applies to 914 speedometers. If one were to use this technique on a 911 speedometer, you would most likely ruin it. 911 speedometer needles come off by turning the needle past its stops. Rotating the needle slightly past the 0mph stop and rotating it past its max speed, all while pulling or putting a slight upward force. Rinse and repeat till the needle pulls off.

I have seen many posts lately talking about broken nylon gears and what not. The 911 speedos use a bakelite plastic material for one of their gears. If you happen to sneeze near it, it will break. People assume that the 914 speedometer has these same brittle gears, I assure you they don't. You will never see a broken plastic gear inside one of our speedometers. If the speedometer is recording speed but the odometer isn't working, 99% of the time it will be that pot metal gear slipping on the drive shaft.

Fixing the slipping metal gear can be done by pinching the gears hub onto the shaft. I know Pelican has a write up spelling this procedure out, but it's not a good repair. I strongly urge anyone doing this repair to use locktite instead.

Since the gear was originally pressed on by the VDO factory, and now it's slipping or free wheeling, pinching the gears' hub with vice grips will only oblong the once circle hole. The now oblong hole gets you 2 pinch points on the drive shaft. We know the gear failed even though it was a tight pressed fit at one point. How long do you think it will last if you pinch it back on the same shaft? This job that you are about to do will suck. It's best to do it once, go the loctite route.
