"the drive sprocket is tiny(8 tooth?)"

the smaller the sprocket the faster it wears out the chain too.

I'll cross it off my list then, I'd rather have a reliable, effective, and easy to repair blower than a conversation piece.

In a way, after dwelling on it for a while, I was rather relieved he sold it.

I will say that the newer models like the OP was looking into,are better engineered than the older models I had.I believe the newer ones used COMMON belts you can buy anywhere-mine used that rare,odd,skinny sucker that costs a king's fortune,and wears quickly.

The weak point of all Bobcats is the chain-driven auger.The driven sprocket on the auger is large and rather robust,but the drive sprocket is tiny(8 tooth?) and they wear incredibly fast if you don't lubricate them constantly.The original sprockets were very well hardened but supplies of the original sprocket/shaft assemblies have dried up.There are guys out there making them,but they aren't hardened well after the welding process and they wear quickly-lubed or not.

I purchased one from a fellow on the net and the sprocket was shot after just a few storms.The assembly is easy to make,but knowing how to properly re-harden the sprocket after welding is another story.


What is recommended for lubricating the chain auger and sprocket on the BobCat?

Whatever lube is put on the chain and sprockets,is not going to stay there.The chain cover is not sealed and snow very readily makes its way inside eventually packing the case full.This is the reason the chain and sprockets fail rather quickly if you don't check the lubrication often.

Oil of any kind is useless.I wound up using a good semi-synthetic grease that didn't harden in the cold.Figuring out a way to seal that chaincase where it runs along the side of the hopper would be the thing to do.I went one step further and just got rid of the Bobcat,as I've stated before,I wasn't too impressed with it.

I've had a 5/20 BobCat for more than 20yrs. While Long Island doesn't get the snow fall that the northern U.S. does I've found that the BobCat is built like a tank as compared to the other brands available all of which appear to use variations of the same design. The most outstanding feature that I have noticed is that my machine is it will throw wet snow, and even slush without clogging. This is a quality that I haven't as yet found in any other machine. In all the time that I've had my machine the only part that NEEDED to be replaced is the belts. It still has the original auger drive sprocket. I lube the chain every year with motorcycle chain lube and oil all of the points as recommended in the OEM manual. A few years ago I decided to replace the old flat head Briggs with a new OHV Briggs. The swap worked out better than I had hoped for, the new motor has much more power, and operates and idles far better than the old one. If today I could a better performing machine for the area that I live I'd buy it...but so far I haven't seen it.

My Dad bought a Bobcat in the fall of '62. I don't think it was any more than 5HP and maybe less than 24' width. It handled every winter in Watertown , NY till he retired and had a service do the snow removal. The times that I used it it had more than enough power to handle the 16" plus snowfalls. The only Bobcat that I have ever seen.
