QuestionQUESTION: I replaced a broken bolt (710-1880),While getting access to the bolt behind the tire, I pulled the tire off and the axle came out a few inches. I put everything bakc together and the problem is when I engage, it will not drive. When I open the bottom cover and attempt to engage the Gear (717-1445) moves but the axle the tires aren't being activated. Could it be the Friction Wheel Assembly? I thought when I put the axle and tires back on I didn't line something up. I didn't have this problem last year and it has happened right after I had moved the axle around. Please help in PA.
ANSWER: I went to their website trying to find out more information and I need the exact model and serial number from your snow thrower. Or you can go to www.troy-built.com and you will be able to download and owner's manual. Without this information I cannot help you solve this problem.

Troubleshooting Auger or Drive Loss on a Two-Stage Snow Thrower
If you experience the loss of auger or drive control, it may be necessary to perform one or a combination of the tasks listed here:
1. Inspect and perform the cable adjustments listed in the Final Adjustments section of the snow thrower Assembly section. Cables do stretch over time. Performing these adjustments will tighten any slack that may have occurred due to stretching.
2. It may be necessary to inspect and possibly replace one or both belts. These belts operate the drive systems for the wheels and the auger.
3. If the belt(s) seem fine and engine runs, but the augers have lost half or full operation, broken shear bolt(s) is/are likely the failure. Inspect the shear bolts and replace as needed. Shear bolts are located along the main auger shaft in the center of each auger spiral. Refer to the illustrated parts list for specific location and replacement part numbers of these shear bolts.
4. For loss of wheel drive, begin with inspection and replacement of the rubber friction wheel (as needed). This friction wheel rubber is considered a normal service wear item and should be replaced when the thickness of the exposed rubber wears to approximately 1/8 inch. This is a drive component essentially responsible for transferring power from the belts to the drive wheels. Operating the unit with worn-out friction rubber may result in damage to the drive system. Check this friction rubber regularly for wear. Consult the Operator´s Manual for more information on friction wheel maintenance.
