Was blowing the snow from our driveway this morning. Not much snow but a whole mixture of freezing rain and snow that would be a pain to shovel so I got out the snowblower. Halfway through I heard a pop and the auger stopped spinning. So I finish off the rest with a shovel and later that afternoon start to diagnose it. Engine was running fine, wheels were spinning so I figured it's probably the drive belt to the auger. Pop a cover off the Craftsmen snowblower, yup, a broken auger belt. At that point I decide to do some maintenance on it since I already had the cover open. I cleaned out the shredded belt (perhaps it was misadjusted from the factory cause I haven't touched it yet, except for an oil change after the first 2 hours of usage. I open the underside and look into any moving parts.
I lube the chain drive with some bike lube and lube some pulleys and stuff, I see that one is supposed to lube the drive shaft that the auger (2 parts, right side and left side) spins around on. Take out the 2 breaker bolts that locks the drive shaft to the auger (hollow shaft). Actually more like I break the breaker bolts as it is designed to do.
Now, unfortunately, one side seems to be permanently fused to the drive shaft. A few squirts of oil frees up the left side so that it spins freely around the drive shaft, but the right one refuses to spin. Even after a few hits with a mallet. I guess that is not normal right? The only thing that will be is I'll lose the safety feature that suppose to break the breaker bolt and release the auger from the driveshaft. Oh well.
But the next thing confuses me, the "clutch" that controls the motor and the wheels is controlled by a friction wheel and a metal drive disc. Pushing the handlebar lever raises the drive wheel which causes the chains to spin and the wheels to move once the drive wheel hits the friction wheel.
Now I'm supposed to use a grease gun to push some high temp grease through a grease port (or "Zert" as it says in the manual) but I'm supposed to rotate the drive disc by hand until the grease port is in front of me. However, the thing doesn't budge an inch, could it be fused or am I doing something wrong? It says to put the drive selector into "first gear" which doesn't seem to do a thing nor do I think it should since the only thing the gear knob does is move the friction wheel closer or farther away from the center of the disc (effectively giving you a change in speed or gearing). It is not til you push the handlebar lever down then you make the friction wheel contact the drive disc. It does nothing else but for the hell of it, I tried every gear on the thing and it doesn't matter. I even tried to "let out the clutch" so to speak and engage the friction wheel to the disc and try to spin the disc that way to no avail.
Anybody real knowledgeable with Craftsmen stuff or should I just ask Sears the next time I'm there? I wonder if I can squirt some lube in the axle and see if the disc will spin. Obviously the disc has no problem spinning with the engine power since the snowblower works great under normal power..
I drained the oil while I was at it and am going to put new one in when I get a new auger belt.
