Try a big slide hammer bolted to the axle. If that doesn't work, I would unbolt the flanges. You can pull the axle out enough to hit the bearings with a big hammer to break the outer race, and then cut the inner race off with a cut off wheel. The next fight is the sprockets. If you can't get them off the axle in the machine, you May have to cut the axles out and press out the sprocket. From there you have 2 options. 1. Press off the sprockets and get new/used pinned axles, or 2. Buy new splined sprockets and axles. I have a set of 6 pinned max IV axles that I took if a 1996 machine if you decide to cut them out. You can just pm me how many you have end up needing and I can get you a price and shipping quote if you want. Member z240 has a bunch of max IV splined axles for sale if you want to upgrade. His axles came right from the factory and are a bargain. The only catch is, you would need to source the sprockets. Good luck. I don't fight axles anymore. I'll save what I can and cut what is too far stuck.
l like to buy stuff and no I don't do payments!
