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

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.

SOURCE: drive belt

You may find that you have the wrong belt - I bought a belt for the correct model and then found that there are two different sizes depending on the exact model - they are 3 inches different in length for my model CTH160 113" and 110". Got correct belt and fits properly now.

Check proper belt routing. These models are a little tricky. Also check tensioner spring.

Snow blower runs and auger/ blade rotates but the wheels Anne not rotating. 2- stage Aries 5520. Not sure if the thrower piece is rotating. Any answers for getting wheel moving/ working


Most self propelled units have 2 belts. One for the auger, and one to power the wheels. Check the belts, and then check the drive assembly under the motor to see if it is engaging.

Tip

Snow throwers


Just returned from the parts store, they had sold out of drive belts for the auger drive on snow throwers... figured I could help out here;

Wet snow is heavy, duh right? Before you run your snow thrower disconnect the spark plug, for safety. Check the chute, and sand any loose paint rust etc. you want a smooth chute.. paint if needed, let dry 24 hours before use, spray with silicon lube spray, this will loessen the stress on your auger belt and hopefully keep your machine running all season. Good luck!

I have a yardworks snowblower however the wheels stopped working


Many of these units are chain driven devices since belts will shrink/slip/crack in the cold wet environment. For that reason, many manufacturers will use roll pins on the axle shaft of the drive wheels and on the driven shaft of the auger. If they get jammed for any reason, rather than break the chain or damage the engine, the roll pin will shear off. Then you simply must replace the roll pin to regain normal operation. See image of roll pin.

I need to tighten the belts on my Atlas Snow thrower


There should be an idler pulley with some sort of adjustment. Usually it is just a pulley with a bolt through the center that goes through a slotted hole on the frame. If you loosen the bolt and move the pulley toward the belt, it will increase the tension on the belt. If the bolt is already to the end of the slotted whole and cannot be moved further in, then the belt is worn and stretched and needs to be replaced. Keep in mind that there are other idler adjustment mechanisms that might be used. This is just the most common.

I am looking for belt size for HABAN 24577 snowthrower to Murray 18hp lawn tractor. Book doesn't provide size info.


I have a Haban Model No. 24577A 42" front mounted snow thrower attachment, which I have mounted to a Murray lawn tractor. I needed to replace the lower drive belt, labeled: V-Belt-Long Part No. 23948 in my Haban manual. I had found it next to impossible to find a replacement belt part number or cross-reference to other brands. I tried many belt sizes and lengths to no avail - belts broke quickly and suddenly after 1 or two uses.

While researching Haban on the internet, I realized that they also supplied snow thrower attachments for Sears Craftsman lawn tractors. A thought hit me at one point in my research... that Haban probably sold the same snow thrower chassis to all manufacturers, but only with different interfaces to the tractors. So I ordered up a belt for a different Haban model that was supplied to Sears, and I think that my intuition was correct!! I have found a belt that works with my Haban Model No. 24577A snow thrower.

The belt that appears to be a direct replacement for the Haban belt part number 23948 (long) is as follows: Kevlar Blue V-Belt 5/8" x 87". It is sold by several suppliers under various part numbers, priced at $20 to $30.

I hope this helps you.

My MTD 10hp auger will not turn. I adjusted the auger cable by tightening the bolt on the handle. I disconnected the spark plug and checked the shear pins on both sides of the auger. They are both still...


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.

Snow thrower won't throw snow


the problem could be the snow is to heavy for the motor to keep up, if thats the case you may need to upgrade to a more powerful model or try not to overload it. take it a little slower so the motor can keep up. but try tightening the belt. with your pointer finger push down on the belt it should have about a half inch give, if it moves more than that its too loose and probably slipping under load
