Revisting mtd 8/26 track drive wheels

I posted in 2017 about the 6 / hp Harbor Freight Predator engine refit and am glad to report I am very pleased with it this far. I also brought up concerns about cracks forming in the hubs of the "Xenoy plastic" drive wheels. Well, it appears that wasn't the weakest point. The lugs that interact with the track have begun to snap off.
I received two new drive wheels today and wondered if anyone could suggest how I might reinforce the new ones to prevent this from happening again.
I suppose a dollop of plastic epoxy would be better than nothing but if there are any better ideas I'm open to suggestions.

Thanks,
MLMcCarren

They look like they've been through it all. Take good care of the new wheels. Don't leave them out in the sun might be the best advise and secondly, try not to let everything rust away like that or you'll be in for more trouble. I hope you can get those wheels off. I have 6,000 SQ. FT. to clear. I also have a 26 Y.O. CC 826T which has been great. The tracks are cracking at the edges but the wheels are fine. It's never been back to the dealer or to a repair shop, nothing but minor repairs and maintenance until now. The first storm this year, I just finished cleaning up and the so called "driveshaft" snapped. It's really a jack shaft, between the drive disk shaft and the axle. The drive shaft contains the steering system which consists of two trigger activated dog clutches with internal planetary gear set. A really solid system but after 1000 + hours of use, the shaft snapped near the end. The two pieces were rusty on the broken ends which indicates that it may have been cracked for some time. Looking at the condition of your machine, I wouldn't worry so much about the new wheels, they will probably outlast the rest of the machine if you can get them on.

40 Hours per year - Wow ! I have over 6000 sq ft that I clear, but I seem to be doing about 10 hrs per year. Where do you live ?

I live in Winchester, NH. The snowfalls here have been getting smaller and smaller over the years but they still come every year and sometimes they are a doozy. I almost can't believe that you are in the Adirondacs(My favorite place to ride.) and can clear 6,000 Sq Ft per storm in only 10 hours per year. It takes me at least 3 hours to do my 10 x 300' driveway, 40' x 50' parking area and all of the pathways to the house and the six outbuildings. I used to also drive it down the road, clearing the mailboxes and then clearing the 120' horseshoe driveway, garage apron and pathways for my elderly neighbor but she passed several years ago and the people who live there now hire a plow. I have also transported my 826T in my pickup to help friends from time to time when we get buried. It has been a wonderful machine all of these years and I want to repair it and keep for a back-up as I just bought a new CC. My old Ariens back up has failed for the last time as well, maybe it should now go to a museum. 54 years old and still has most of the paint on the auger. It's a fast machine and I used it for all the pathways around here back when we had a plow guy. but I have been retired for 16 years and I just don't feel like messing with this stuff anymore. I'm pretty sure my new CC will outlast me and if it's as good as the old one, I'll sell the 826T, a great machine.

Well, clearly looks can be deceiving. I assure you that I have... "not to let everything rust away like that". It's kept inside when not in use.
In fact, I plan on throwing snow with this unit for the next decade at least. I just put a 212cc, 6.5hp Predator engine on it September 2017.
I agree ultra violet radiation may have been the cause of weakening the wheels, but I don't know anything about it prior to 2017.

I can not imagine how any rust could be a factor in your machine failure if you keep your skid plate and belt guard In place

Mine looks brand new inside...
