I have a Toro 724 snow blower that just gave up on driving in second
and low gear. Looking at it I figure the friction drive wheel is worn
out and I purchased a new one today but I fear I may not be able to
figure out replacement methods.

Anyone done this replacement and have some tips or could direct me to
a source for information,

Thanks,

Gene

Hey Gene I have replaced those before. It might help if you go to toros
home page they have schematics and diagrams free of charge in pdf form.
Very helpful for getting a part number to. You will need to flip the
machine up on it's front end or lift it up on jack stands under the
axles. If you flip it up first pull the starter through till you feel
the point with most resistance. You want all your valves closed so the
exhaust and carb arent drenched in gas and oil. Remove the lower pan
bolts. inspect the disk for excessive wear. Also dont forget to check
the bushings the shaft rides on. I have had to replace those before.
They act up early when you put it in reverse it slips. Works in all
forward gears but slips in reverse. After awhile it can affect all the
gears. To get the clutch out takes time. Usually have to remove a lower
jackshaft or disconnect a chain on the older ones. No special tools are
required just some elbow grease and time. Good luck.

Oh I forgot one thing. Check the tension on the clutch handle. Follow
the linkage down the handle. you should see a adjustment for the clutch
and the auger. Put a few turns on it and see if that solves the
problem. Clutch disks wear over time however you should be able to make
small tweaks to it over the years. If this works take the friction
wheel back and buy a cup of coffee and give yourself a pat on the back.
