Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Hi all, looking for some help.

I have an ST824 that is about 20-25 years old that I got from my Dad when he retired. Last year it worked like a champ, but one of the kids left something in the drive that the rakes picked up and got jammed on. Unfortunatly the shear pins did not shear. Now, the fan will rotate, but the rakes do not. I am assuming something is pooched within the gear box iteself, but have not had it apart to see what.

How hard is it to open this up and service it? I am fairly handy and have a heated garage, so I'm not too scared of it. From what I can tell it is a simple worm drive case?

Also, what is a good place for replacement parts? For some reason I am having trouble finding an Ariens service dealer near me (far west suburbs of Chicago). The online places all seem to want around $200 for a whole new gear box.  I'm out of work here in a few weeks, so obviously looking to save a few dollars.

Thanks!
