Speedo Needle R&R Advice Needed
« on: March 05, 2011 - 02:18:05 PM »
The speedometer needle on my car broke off and I need to find out how to remove the whole needle from the shaft.  Does it just press on or will I break it if I try and pry it off?  And if I can glue it, any idea how this will affect the accuracy of the gage?  Does anyone sell replacement needles?

Hold on to the circular silver wheel attached to the shaft at the bottom so the shaft isn't against the stop. grab the needle with your thumb and index finger and twist it to the left, while pulling it up.  A sticky speedo or binding cable will break that needle.  I have 3 broken ones.  Kinda makes me want to get an electronic speedo and put it's guts inside a stock one.

Everyone with a jumping speedo should worry about this breaking off.  If yours is jumping , pull the cable off till you get it fixed.

Thanks, ShelbyDogg.  Yeah, just before it broke it began bouncing and vibrating along with a clicking sound coming from the cable area.  Then I saw the needle fall off. 

Does anyone sell replacement needle?

Here ya go, I was bored. Quoted fron Gregg's site;

Ebody Rallye Speedo Needle
If your speedo has a broken needle, this needle can be glued right over the old broken needle. We also recommend that you carefully check the speedo to see if it needs servicing, as sometimes the bushing on the back of the speedo is worn and can allow the speedo cable to grab the speedo needle which causes it to break.

Cost $30

More info on speedo needles
•Reason 1 why speedo needles break: If the speedometer cable is dry and needs to be lubed, sometimes the cable will bind and then jump forward, causing the speedo needle to swing wildly and break.
•Reason 2 why speedo needles break: If the nylon bushing inside the speedometer is worn out and it allows the aluminum cup to touch the rotating magnet then the speedo needle can break.
•Reason 3 why speedo needles break: If there are metal shavings or rust pieces stuck to the magnet which allow friction with the aluminum cup, then the speedo needle can be broken.
•You can't use this speedo needle on tachometers.


How to remove Tach and Speedo needles from Mopar speedometers
•Take the speedo out of the instrument cluster

•Grab the aluminum wheel in the back of the speedo with one hand and don't let it move.

•Grab the speedo needle with your other hand, holding only the black round part, and twist the needle back and forth and gently pulling the needle off the stem.

•Put it back on the same way except push on it.

The only danger here is that you might bend the needle pointer/tail, so it is best not to touch that part of the needle.

You can remove the tach needles the same way, but you don't need to hold the back of the tach. Instead just twist the tach needle past 0 RPM while gently pulling on the needle.
