I am rebuilding the gearbox in my 824, and I do not know the direction of the helical gear. The new gear is stamped "R->" on one side. Does that mean this is the right side of the gear as viewed by a person operating the snow thrower? Thanks.
I took the old gear off the shaft without thinking about this so that's no help. They do seem to mesh somewhat better one side vs the other but I'd really like to confirm before full reassembly. Thanks
Click on "Homeowner Parts" on the bottom left under Parts & Manuals.
Then put in your model number. Probably 38xxx or 35xxx.
Short of that, I can't really help any. I would agree that R would sound like right side from operators position. Any chance the pin that holds the gear to the shaft is off center slightly that that in will only fit one way?
Just thought I'd post back. I did hear from Toro. They directed me to a service manual on their website. It was very thorough on how to rebuild the gearbox (and it looks like the rest of the machine as well)......except gear direction!
