Speedo/Crank bearing bad?

[Meat-Run]

I've picked up a 99 Pantera 580EFI with speedo that doesn't work is this a sign of crank bearing gone or going? I know this was the tall tail sign on all the polaris's that I've owned but don't know if AC does the same thing when speedos don't work. Any AC mechanics that can link crank bearings and speedos going out?

thx

More than likely. Same thing happened to my AC. Look underneath and see if the shaft is off center.

AC speedo goes to the track drive shaft/bearing not the engine crank shaft.

I knew that....

Most people forget to grease this bearing as it is very hard to even see the grease fitting unless you know it is there. I found mine the hard way to and cost me a few hundred in parts as the drive shaft was also damaged and needed to be replaced.

Often, that grease zerk on the spedo gear assembly on the Arctic Cats is there to lube the gear itself ( and keep the water out ) and not grease the bearing, from what I've seen, those bearings are 100% sealed.

When people don't put grease in there, snow / water get's in and corrodes the gear assembly and it locks up and twists off that square key that gets driven from the shaft that drives the track.

With that being said, I would definitely check the track drive bearings, my rule was that I changed mine every 5 years whether they needed it or not, saved a lot of headache on the trail or lake.

No gear in mine and the speedo cable just plugs into the end of the shaft. That's why the end breaks off when the bearings start to go and the shaft starts to wobble. The grease fitting is in the cover plate and will push grease to the bearing. My machine is a 98 so maybe new sleds have a different set up.
