OK guys, I am looking for some help/advise on this one....I changed out my speedo bearing last weekend and put a new speedo pin in at the same time. The bearing wasn't really bad but I figured the speedo pin broke for a reason and I was that far into it so I just changed it.

Well today I have noticed that the speedo reads pretty normal up to about 45 MPH but after I increase my speed well above that...like 80, it only goes to a max of about 55. It doesn't jump around or anything strange, so at this point I am unsure of what might be going on. Maybe the cable is worn out internally and causing this?? Could that have also been what caused the pin to break?? There doesn't seem to be any binds in the cable.

Or is there something going on with the speedo guage itself? Like I said above I am at a loss here but don't just want to start throwing parts at it if someone on this AWESOME SITE can direct me on this one.....

The sled has 5900 miles on it and I wouldn't think the speedo guage is wore out but then again I wouldn't think the speedo cable would be either.

The sled is in the garage warming up as we speak.
Thanks in advance for the help guys......

If you have checked the following . . .
  • speedo key in the drive shaft (doesn't slip)
  • speedo joint (the pin you referred to)
  • speedo gear housing (make sure it moves freely and doesn't slip)
  • speedo cable (make sure it spins freely - you may want to dry lube it)
  • speedo input shaft spins freely
Then you may have a problem with the speedo meter itself. I would swap it for another temporarily to test. Or hook it up to a variable speed drill motor to test (just don't put too many miles on it, lol)
 
Thanks for the info Ding.

This is what I have found. The speedo pin is not sheared off but it is twisted & stretched. That's were the lower speed was definitely coming in. Checked the cable and it spins freely. The same was found for the speedo and speedo gear housing.

There is only one thing I can think of that might have caused this. The bearing set screws were tightened after I pushed the bearing onto the axle as far as I thought it needed to be. And that was before the speedo gear housing had been put on and completely tightened. Maybe the housing needs to be tightened first. This would push to bearing ALL the way onto the axle and set the correct distance for the pin. If the bearing is not all the way on there may be some slop for the pin to move back and forth and possibly cause my dilemma.

Your thoughts?
