st824 Maintenance Question

Hello,

So I have the wheels off and they are going to get new tires. I bought oil and marine grease. And I plan on taking off the rust on the augers and impeller and repainting them.

Any suggestions on anything to keep an eye out for when I place it on the auger housing and open up the gear and friction plate section?

Also, it seems as though the machine has a hard time starting with the pull starter, should I be looking at the flywheel key, carb, or something else to get it to start easier? The electric start gets it to go.

If you are pulling the auger off you will want to check the bushings/bearings for excessive wear, and replace if necessary. A low temp grease is recommended for snow blowers due to their cold operating environment. The friction plate area is pretty straight forward...clean with a degreaser so that the plate is clean and dry. Wipe down the drive disk "tire" to remove oily residues. Lightly grease the hex shaft that the disk moves along to make shifting easy.
Starting problems can be fuel or ignition related. Most are avoided by maintaining a clean carb with fresh fuel in the tank, and using a good spark plug, properly gapped and valves adjusted to specs. MH

Electric start gets more volume to the motor(gas and air) because it sucks and draws more and faster than pull start. If you see this with your current setup with pull start attempts, your carb is dirty. One click on the choke will likely make your's pull over easy. Again, dirty carb. Correct spark plug, known spark timing and clean gas make these machines easy.

+1 on clean, fresh gas and new spark plug.

The meltdown is under way ...

So the pull start works just fine, I took off the carb bowl and shot carb cleaner up the main tube (emulsion tube?). This machine has had some carb work done, new throttle. But it runs good.

The gears and shafts (hex and axle) had very old black grease on them, I cleaned them down as best I could and applied new marine grease. The grease zerk on the axle, outside the housing seems clogged or something. IT connects and it seems like grease should be going in but then no new grease appears on the on side where the axle is close to one of those big gears.

Also, the seal that holds the axle into the housing on one side seems worn, the axle has a little play on that side. I can move the axle about a 1/4 inch up and down, but it does not slide in and out of the housing at all.

I have the wheels off, does this rubber seal need to be replaced to stop the axle from slipping out of place? How urgent is this?
