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.

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.

SOURCE: How to adjust the Toro 826 snow thrower

Belts will have spring tension on the idler pulleys.
Both traction and auger control cables will also have cable length adjustments to cause the travel of levers or idler pulleys to tighten belts. Adjustments are commonly located under the control panel/levers.

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.

I have a ariens 24 "sno tech it will not throw


The most common cause of this is the drive belt is worn. If you remove the cover (usually plastic) in the middle of the snow thrower and look at the belt closest to the blower assembly. This is the blower drive belt. (Your operators manual will show you the location and how to remove the cover if you are unfamiliar with your snow blower)
With the engine not running, have someone depress the drive lever and check the belt. You should only be able to depress the long side 1/2 inch or less. More than that the belt has stretched and needs to be replaced. On some older blowers you can adjust the tension pulley, but most made in the last 15 years, you can't.
The belt may be frayed on the edges or glazed causing it to slip (it is shiny on the sides of the belt)
You can get parts (the new belt) through your local Ariens dealer or jackssmallengines.com

Changing auger belt on snow blower


The most common cause of this is the drive belt is worn. If you remove the cover (usually plastic) in the middle of the snow thrower and look at the belts.
Your operator's manual will show you how to remove the cover and check/change the belts.
I am going to assume you have a Craftsman snow blower. If you don't have a copy you can get the manual through managemyhome.com
You will need the model number off the snowblower. It is usually located on the bottom right hand corner of the frame (from the handle side)
The model number looks like 247.123456.
The belt closest to the blower assembly drive the auger/blower and the belt closest to the engine drive the transmission.
With the engine not running, have someone depress the drive lever and check the belt.
You should only be able to depress the long side 1/2 inch or less. More than that the belt has stretched and needs to be replaced.
On some older blowers you can adjust the tension pulley, but most made in the last 15 years, you can't.
The belt may be frayed on the edges or glazed causing it to slip (it is shiny on the sides of the belt) It may be torn and broke completely.
Your Craftsman manual will show you step by step how to change th belt.
You can get parts for you Craftsman and most MTD made models through searspartsdirect.com. With other makes you can get parts through jackssmallengines.com
If you are unfamiliar with repairing machines you can get your snow blower repaired by taking it to your local Sears.
They will have a technician troubleshoot and repair the unit.
