Default QA42 1450 Gearbox Rebuild and Mod

I've found a little information but I don't have the manuals to complete the fix either.

Long story short I was out with snow deep enough to use a snow thrower (for the first time in a while here in Michigan) and it did fine for a while but then the 90 degree box gave out. Now the box has always had wet around some of the seals but I always checked it for noise and never found any. Now the input shaft is the only thing spinning and I imagine I'm probably missing teeth on the interior.

I do have a tiller box which I understand is the same part. Please correct me if I'm wrong.

The largest problem I was having with the thrower itself is clogging. I would be willing to bet its because the exhaust is blowing hot right on the chute area. Since this is a permanent project I figure adding a stack onto the exhaust would relieve this problem.

The second largest problem is the speed of the auger. I imagine dropping an inch or even half an inch on the pulley size would take care of this but would this drop too much torque from the belt grip? Just looking to see if anyone has walked this road. I know someone has.

And since I've probably cooked a gear is there a place where I could get some new gears? Also I imagine I need a press to remove and replace said gears from the input shafts. If I'm going to rebuild the box I might as well make it tough again.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
