Open Question

I have a MTD 13AT688H131 Husky, 21 hp, and I can not keep the lower drive belt from coming off. The repair person has replaced belts twice and even the double pulley. What the heck is going on?

SOURCE: 826LE Power Max Snowthrower_ Drive belt keeps coming off

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

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: belts slipping and breaking

If you are putting on the mtd belts and installing them right then you need to check bearings in variable speed pulley Also check idler and that no other pulley has been bent from installation.

SOURCE: MTD Lawn Tractor: Constantly shredding deck belt...

I have the exact same model MTD tractor with same problem. It began when the bolt that extends through the idler arm assembly broke and subsequently damaged the pulley. Upon examination of the broken bolt, I found that the threaded end that extends below the deck is significantly smaller that the rest of the bolt. I got a larger bolt with the same size threads, bored out the hole through the deck and it made the whole idler assembly much stronger. the deck still has some vibration and some unusual belt harmonics, but it appears to be working. Compared to most other tractors of this size, this deck is very complicated.

Belt for self popelled mower keeps breaking? Cannot keep a new belt on pulley


Check that the pulley isn't seizing up and causing the belt to snap, also be sure you loosen up the self propelled mechanismn by spraying down with WD 40, too much belt tension can cause this, but it rather seems like the belt pulley seizes and the engines drive pulley keeps turning causing the belt to overheat and break or stretch and come flying off.
