74' CJ5 Speedometer

Hopefully this is a "quick" question. I have a 74' CJ5, and the speedometer is buster. The needle is just hanging around in there.

A. Is this easily fixed?
B. If I was to buy a replacement, what years are compatible? I've read that the OMIX ones are junk..

C. How do I remove that bad boy? Can it be done without removing the dash?

It depends on your problem. The issue could just be that your speedometer cable, which runs from the back of the speedo to the transfercase in my 78, is broken. If you search around you can find testing procedures to determine if this is the problem. Or the problem could be with the actual speedometer magnets which move the needle when your cable spins. This case would require that you replace your speedometer.
In response to your other question, the speedometer assembly is held onto the dash on the back side with 4 3/8" nuts on my 78. Extremely easy to take off compared to some things on the Jeep...
With aftermarket replacements I've really only seen the ones that go from 0-90 mph, 5-whatever mph, and the ones for km/h.

Its not the cable, the miles are still ticking by I just can't tell how fast Im going. So any CJ speedo should fit as long as its the same range? Im probably just going to get one off of ebay if I can.

Check out http://classychassisrestoration.com

Talk to Kevin and he can talk you through sending yours in. I am like you and didn't want to have to use a cheap knockoff of my gauge. I have all mine enroute to him for restoration and he checks them all for accuracy before sending them back to you.

Thanks! I'll be sure to check them out, I just got done taking out the old one... it may only be 4 3/8" nuts but that's a royal PITA...

Well... took all of 5 minutes to find the problem... the little pine for the needle is busted in half. Hense why it was still ticking over miles but not showing a speed.

Will any CJ 0-90 gauge work? I noticed my gauge's face only has lights for left, right and high beams but it has bulbs in back for much more.

I think they will. I had problems out of the one on my 75. I took it completely apart and used some parts off a 78 that I had. I wanted white face gauges, but the original look so I sent it to Zach at whitefacegauges.net I believe. They calibrated (or whatever) the speedometer and checked everything out. It looked great when I got it back.
