Toro 826LE snowblower...impeller engages only randomly

I have an 826 LE Toro snowblower. When I engage the auger drive, nothing happens. When the snowblower is in this condition, I can spin the impeller, but the augers do not turn. I had the same problem earlier tonight...I took the belt housing cover off, and really did not do anything (did not change belt, etc)...I put the belt housing cover back on, and then fired it up. The impeller/auger then worked as normal. I snowblowed the driveway, then the issue happened again. I can free spin the impeller without the auger drives turning. Both shear pins in the augers are good. What seems weird is that I can grab the impeller and pull it back and forth from the back to the front of the machine...this seems odd.

Do I have a minor problem, or is this the sign of the gearbox giving up the ghost? Why would this issue seem intermittent in nature?

Any help you can give would be greatly appreciated!

    Thank you very much for the posting.

    One additional piece of info. There should be 2 shear pins/bolts that hold the impeller onto the shaft that goes to the gear box. I no longer have those bolts there...I guess they broke...I tried to put another bolt in there, but it will not go. I am not sure if there is a piece of the former bolt stuck or what.

    I actually went to a parts shop today and they pointed out that they believe the problem to be the "helical gear". Is this the worm gear that you mentioned?

    As I had suspected, once I installed a shear pin (bolt) into the hole that attaches the inpeller to the shaft, it works like a charm!

be careful, if the engine over revs it may just explode. These engines are very picky if over sped and easily blow up.
Your problem may be a broken throttle control rod, have look at that first. If the control rods are fine and in place it could be the fly wheel governor is worn out.

SOURCE: mtd snowblower 4.5 no spark new coil,new plug

Hello pbck98:

>>The Following is a Basic Instruction File I Made for Checking the Coil/Ign Coil/Magnetron/Armature on Small Engines. Any Input is Appreciated.
>>**To Check the Ign Coil; Remove the Spark Plug/s.
>>With a Good Plug, Wrap a Wire Around the Threads of the Plug and Attach the Other End of the Wire to the Engine Block. >>Remove the Blower Housing (metal engine cover). The Wire that is Connected to the Coil/Ign Module from the Shut Off Switch needs to be Removed (unplugged) from the Coil/Ign Module.
>>Now Check for Spark at the Plug.
>>If Spark, then the Shut Off Switch or the Wire is Bad.
>>If Still No Spark, then the Coil/Ign Module is Bad. If there are Safety Switches on this Unit and the Coil is Good; you Need to Check the Safety Switches for Being Bad and Check the Oil Guard Switch also.**
>>If you have a New Coil/Ign Coil and Still No Spark, then
>>Turn the Coil Over and Check for Spark. Ign Coils are Wound 1 Way for Clockwise Engine and the Oposite Way for Counter Clockwise Rotation Engines. I have Seen Ign Coil Boxed Wrong and Turning the Ign Coil Over will Correct the Problem.
>>The Coil is Gapped to .015in from the Flywheel.
For Better Assistance;
>>Send me the Make, Model and Type or Spec Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you.
Please, Do Not Hesitate, If I Missed Something or you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance.
Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Be Happy. Thanks.

Good Luck

SOURCE: my yardmachine snowblower won't stay running. It

empty the fuel bowl & tank. start out with fresh fuel for one. then get a new spark plug if it still dont start. as far as the cable thats another deal completely but it shouldnt cause it to stall out. but if it ran last year it will this year too. always run it empty for summer storage. its your personal choice if you use a summer storage lubricant.

The bearing can be a bugger to remove....and it sounds like the bearing may also be bad... so you will want to replace that also...
To get it off make sure that the set screw(s) are backed out with an allen wrench...the set screws will be in a small hole in the lip of the allen wrench is a six sides wrench that comes in many sizes... the screws may also be a metric size...

then to remove the bearing you will need to use a gear puller that will grab the bearing equally with thre jaws and the use the shaft for leverage as you turn the screw to pull the bearing off of the shaft...
You will bugger up the shaft if you keep trying without the proper tools and then you will really have a mess on your hands...

SOURCE: My MTD 10hp auger will

Yes there are 2 belts one for the drive and one for the auger. If you remove the cover on top that is located between the engine and the auger housing you can check the belts. The auger belt has come off the pulley or is broken. Hope this helps you out. Best regards and good luck.

Snowblower wont go into gear

Hello Jean,

First, remove cover between auger and engine and inspect belts, you should have a drive belt and an auger belt. If both of those are ok then check all linkages from the gear shifter and handle down to the base. Second, you will have to tip unit forward and rest in up position. Next, you will have to remove the plate on bottom of unit. You will see a rubber disc that presses against a friction plate when you squeeze handle to engage drive. These rubber discs do deteriorate over time. I'm confident once you look at internal workings of drive system you will quickly understand how they work. I would bet its just a belt but if you follow the steps above Im sure you will see the problem. Good luck and Happy wrenching!

I have a snow blower which will start up but it won't move forward in the snow nor will it push the snow. Not sure what is wrong. I can manually move the blade around that pushes the snow.

If you start the machine and the axles spin but the augers do not it is because the shear pins are broke. If you look closely you will see the the augers have shear bolts and nuts or shear pins. If you jam a piece of ice or a stick in the augers while they are spinning the bolts will shear so you do not damage the expensive augers or the worm drive gears. If the axle spins with the augers you may have torn up the front worm gear in the front of the auger intake. If you spin the small auger and the large auger moves but when you start and engage the auger nothing happens you will have to remove the under cover and inspect the drive belt pulleys for jammed or broken parts or more commonly broken drive belts.

I have Toro 826LE model 38620 S/N 250010001 & up snow thrower; one side agur will not turn under power and free wheels by hand. The problem occured this morning, there was no indication of a problem...

It sounds like you have sheared a roll pin. Look at the auger that is not turning, on one end you will see a hole, there is a steel pin that goes through the shaft, I am pretty sure that pin has sheared and allows the auger to spin freely on the shaft. You may have to find a small punch and drive out the broken piece before inserting new one. Seeing how the auger has been spinning on the shaft you're gonna have to line up the hole in the auger with the hole in the shaft. Look at the good side to see alignment. Hope this helps ya.

you have to ssplit the snow blower in half to get to the belts. Its easy but make sure to replace both belts and also check the auger bearing they are known to wear out and the auger belt will not get tight. The bolts are on ether side behind the auger assm
