Just finished changing out my right idler gear and shaft. Couldn’t see much wear with the chains on but noticed a tooth with a broken edge. Removed the gear and found quite a few teeth rounded off. Decided to pull the idler shaft and found one tooth partially broken also. Since I finished the right side i’m Going to go a head and do the left side as well. I’m using the chain wax on my chains along with some chain graphite. This chain wax from my Argo dealer is expensive, any suggestions on other types of chain lube on the market that a guy could use? I lube about every ten hrs operation. Maybe fatigue being 2006?
