I recently bought a used Craftsman 917.376677 (917376677)
The mower in like new shape. The owner told me he had replaced the two front wheels as part of his most recent maintenance routine. The problem is after getting it home and mowing with it for less than 10 minutes, the front wheels started to slip and make a grinding noise. I removed both wheels and noticed that the plastic teeth inside the wheel hub were freshly chewed down. It's obvious that the metal pinion gear is chewing the tips of the plastic off the wheel. The question is why so quickly?
So after doing a ton of research, this is what I found.
This Mowers model number is 917.376677 (917376677)
Here is the parts breakdown page for that mower
https://www.searspartsdirect.com/mo...aftsman-917376661-gas-walk-behind-mower-parts
The correct wheel part number for this mower is #532403111 which is apparently for 22" mowers (Craftsman, Polan, Husqvarna)
https://www.searspartsdirect.com/product/23bsy7gir8-0071-917/id-194231x427
Wheel specs are:
Size - 8"x1.75"
Hub Offset - 1-1/2"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The wheels that the previous owner put on the mower are #5321807-67 (532180767) which apparently is for 21" mowers (Craftsman, Polan, Husqvarna)

Wheel specs are:
Size 7-3/4"x2"
Hub offset - 1-5/8"
Here is one of the models that this 2" wheel fits

Each of these two wheels uses a different pinion gear. If you open both pages for each of these mowers and compare the metal pinion drive gear that fits each of these wheels, you will see there is a huge difference in their overall shape and design.
What are your thoughts?
Should these two wheels be interchangeable?
