Re: 826LE Power Max Snowthrower_ Drive belt keeps coming...
Part # 94-8812 is traction belt 106-4498 auger belt
There is a service bulltin on this I have not seen this yet, Ill paste it for you to look at .
this was issued dec 22-2003 you would think that it would have shown up as a problem by now.
UNITS AFFECTED: Model Number(s): Serial Number(s): 38620 240000001-240999999 38621 (Int'l.) 240000001-240999999 38632 240000001-240999999 38635 (Int'l.) 240000001-240999999 38642 240000001-240999999 38645 (Int'l.) 240000001-240999999 38652 240000001-240999999
SUBJECT: Traction belt jumps off the pulley. SITUATION: Incorrect pulley alignment causes the traction belt to jump off, usually when the drive is disengaged or as a hill is crested. CORRECTION: 1. Remove the belt cover, engine belt guide and the bolt securing the crankshaft pulley. 2. Remove the auger brake assembly. 3. Remove the crankshaft pulley and the auger belt. 4. On the left side of the machine, remove the hair pin cotter from the speed control link and slide the link out of the pulley pivot assembly. The traction belt can now be removed. 5. Shorten the pulley half nearest the engine (PN 106-7334) shown in Fig 1. Grind or machine 1/8” (.125”/3.2mm). from the hub end of the pulley. The new finished length of the pulley half should be 1.07” (2.7cm). 6. Chamfer the bore to ensure the pulley fully contacts the shoulder on the crankshaft. You can send the pulley to an outside machine shop if you do not feel that you can modify the pulley in house. 7. Reinstall the pulley with a new traction belt. A. Chamfer edge after grinding/machining. B. Remove 1/8”. C. Masking tape used as a reference line. 8. With the engine off, engage both the traction and auger levers and inspect the alignment of both the auger and traction belt idler pulleys (Fig. 2). Since we have moved the crankshaft pulley it may be necessary to bend the idler arms slightly to center the belts. Adjust as needed. 9. Install the engine belt guide and test operate. 10. Install the belt covers.

1. Remove the belt cover with a socket wrench. Slide the belt cover off and set it aside.
2. Remove the two belt cover stud bolts with a socket wrench to get to the auger belt guide.
3. Remove the belt guide with a socket wrench.
4. Push down on the belt tensioner pulley with your hand. Remove the old belt and set it aside.
5. Install the new belt and release the belt tensioner pulley to tighten the belt.
6. Re-install the belt guide with a socket wrench and tighten the bolt.
7. Re-install the two belt cover stud bolts and tighten with a socket wrench.
8. Re-install the belt cover and secure it with the cover bolts. Tighten the bolts with a socket wrench.
I pulled the following from a snaper model similar to yours.
The snowthrower has two drive belts, one for the traction
drive-which transmits engine power to the wheels, and
a second for the auger drive-which transmits engine
power to the auger mechanism.
Each of these drive belts are of special construction and
should be replaced only with genuine replacement belts
which match the original equipment belts. These are
available from your dealer.
Traction Drive Belt Replacement I pulled the following from a snapper model similar to yours. Believe it should help.
1. Disconnect spark plug wire and fasten it away from
the spark plug.
2. Remove belt cover. (Located in back of the discharge shute).
3. Pull the traction drive belt idler pulley arm (See
Figure 24) away from the belt to relieve tension, and
slide the belt off the engine pulley.
4. Slip the belt off from around the traction pulley (See
Figure 29) and pull the belt out of the unit between
the auger pulley and the traction pulley (the lower
cover need not be removed for this step).
5. Reverse the procedure to install the new belt. Be
sure there are no twists in the belt, and that the belt is
properly seated in the pulley grooves.
6. Replace the belt cover.
7. Start the unit, and check the traction drive for proper
operation. See "Traction Clutch Cable Adjustment"
for adjustment procedures.
There are also several videos on YouTube on changing snowthrowr belts. (Didn't see one for your blower, but most similar and should provide a good starting reference).
Hello, My name is Dane and I am going to help you solve your problem. Your Hydro drive belt Part number is sears part number 140218 which is a 1/2 x 84.5" belt. Well, I hope I've helped. If you found this reply helpful, please leave me some THUMBS UP if you think I'm deserving! :-) Thank you! Dane
You will have to disconnect the deck from the tractor. There might be
some rods hanging down by the pulley on the motor. You have to loosen
those not remove. Then install the new belt with the inside of belt (V)
into the pulleys. The outside of belt (flat side) goes up against any
idlers (oversized pulleys). Once you get the belt routed properly the
belt will be snug in the pulleys. If you have excess play you have to
use trial and error to get the belt routed the right way around the
Once belt is on reattach the deck and tighten the rods by the motor
that keeps the belt from coming off. They need to be close but not
touching the engine pulley.
my cub cadet used to throw the cutter belt too....till i took the drastic step of adding a bit more tension to the belt. this was achieved by drilling another hole on either side of the chassis about 1 3/4 inches to the rearward of the machine and moving the lift arms to the new holes. Viola, more belt tension, and furthermore there is now no interference between the tensioner and the rearmost run of the belt.
I have the same machine and it sounds like the belt is indeed slipping. If the belt is not worn or stretched too badly, you can perform a small adjustment on the idler-wheel (the thing that controls belt tension) by sliding back the plastic cover on the spring that is attached to the bottom of the lever-cable and tightening the nut so that there is less slack in the cable. If the nut is all already all the up, then you need to replace the belt, which can be easily accessed by removing the plastic cover in front of the motor under where the spare shear pin compartment is located. There are two bolts (one on each side) that need to be removed and then the cover just pulls off. This will expose both belts. The front one is for the auger drive and the rear one is for the wheel drive. The belt can be easily replaced without any further dis-assembly by simply removing and replacing it in the reverse manner. Don't forget to readjust the spring so that excessive tension is not applied to the new belt. Hope this helps.
