A few of the better made snowblowers have 'O'ring chains on them, others use gears on the shafts. Cheaper made ones use a plain Non 'O' ring chain.How many snowblowers have O-ring chains?
Most of my bikes go through at least 2 driven sprockets before they wear out a drive sprocket.Oh, and if curious as to the lifespan of a street bike O-ring chain, the drive sprocket (the one on the engine output shaft) is good for around 10k miles. The O-ring chain and driven sprocket usually see two drive sprockets before total component refresh.
OUCH! That's no fun.The good old shaft drive ST1100...
Funny story. During the 2003 running of the Iron Butt Rally I was slowly motoring though Eagleville, California around 3:00am during a rancher sheep drive on my ST1100. Needless to say, it was bahhhhhhhhhd. ;-) The bike had just rolled over to 142k on the clock as I passed through town. I looked at the odo and thought, "This bike is going to see a quarter of a million miles easily..."
Three miles later I hit a deer at 65MPH totally destroying the front sub-frame of the bike and ripping open the radiator. My rally effort was over... Thankfully, my person sustained no ill effects from the collision. Although, I did get a bit of deer scat on the right leg of my Aerostich riding suit.
Here's a photo of the damaged bike:
I hope you didn't think that I was being arrogant with my answer, I never THOUGHT to lube the chain, and I was thanking for the info on chain lube.
