Cross Reference for Gm Stepper Motors

Cross Reference for GM stepper Motors =

Cross Reference: X27 168, X27-168, X27168, X25 168, xc5 168, x15 168, x25-168, xc5.168

THINKING X27 168 is the latest and greatest will see some with lifetime warranty which means nothing but I did see that the solid black stepper went down to minus 40 I will probably go with the black ones.

A pic of my original stepper on the back side of the circuit board from an early 2003 ProStar Tournament Team boat

The Stepper motor contacts on the front side are numbered 1, 2, 3, 4. Instead of taking the soldering iron and heating the contact point or board directly, I would take something small metal round and hollow and slip over and set on the solder heat indirectly, But I don't know, haven't done it yet. Lets us know how it works out for you.

Just a note:

Before pulling the needle of the face ( can lift needle off with a fork ) turn needle counter clock wise to (ZERO) bottom out. MARK/Place a piece of tape under needle to mark original needle position, so the the speedometer reads correctly after installing the new stepper motor.

Stepper Motor solder points 1,2,3,4

You might want to nip off the old stepper motor wire leads before warming the solder points to remove the stepper motor. You can see the the wire leads are marked on the board 1,2,3,4

Replacement Stepper Motor

Project is starting to get on track...bought some stepper motors off eBay, trying out the black stepper motors supposed to be lifetime, and they do look like they are made better will see, the soldering pins look to be made of a better material. Ice is off the lake, so a couple months to get the boat back in the water. Here is what the new stepper motors look like. Then people will be able to fix their original gauges, which should cost less & and everyone will be happy hence World wide including me!

Can you post a link to the eBay seller or post a part number? Mine work fine at the moment, but it might be a good preventative project.
Oh yeah- and take lots of pictures!!
Thanks,

I'm all about preventative maintenance - but, having done this repair myself, I'd say "if it ain't broke, don't fix it". Perhaps purchase the steppers to have on hand, just in case. But I wouldn't tear into a working gauge if you don't have to. Too many things to go wrong in the process which could then render a perfectly good gauge useless.
