Hi, I have an indy600 Polaris that's ticking when I drive it. I think it may be coming from the jack shaft area. Im not sure how to troubleshoot it. Any ideas on what this would be? Is it common for the jack shaft bearing to go and cause ticking?
Which side is it on? Chaincase side bearings don't fail very often, as they get lube from the chaincase fluid. A ticking sound on that side could also be a chain that is not adjusted properly or a worn chain or adjuster. On the PTO side, the driveline bearing fails more frequently, as it's exposed to snow/ice/water under the tunnel. Usually the driveline bearing failing will cause the speedometer key to shear and you lose the speedometer (that's a first sign of an issue.) Sometimes a ticking sound on the PTO side can be coming from the flyweights if the weight bushings are worn excessively. That's a few things to check... good luck!
