Replacing jack Shaft Bearing
First let me say that I am new to snowmobiles, I am familiar with ATV’s but I just bought this snowmobile in February so if I misstate anything please correct me.
I have a 2007 Z570 that I’ve ridden once and at the end of our ride it started making a clanging noise and losing power, so we towed it the rest of the way back and parked it. We suspected at the time it may be the jack shaft bearing as you could pick up the jack shaft by the brake rotor and move it freely. This weekend I finally tore it apart, drained the chain case and removed the cover and as I suspected it looks like the bearing is the problem. The shaft and top sprocket move around keeping the chain from having any tension. I have not gone any further than taking the cover off of the chain case, the sprocket it still attached to the shaft. So my question is what is the best way to replace the bearing? Does the shaft have to come out to replace it? If so how much work is it to remove the shaft, it looks like it could be a bitch. Also is there anything else I should check or replace while I am in there?
