>>2017403can you please whip out calipers and do as good of a job as possible measuring the following:
OD of the seal, ID of the seal, depth (axial dimension) of the seal. Also can you spot a spiral spring when looking from the rear? Is there exposed metal along the OD of the seal where it's pressed into the seal? Any markings?
Bonus if you can sketch the lip of the seal. I'll provide an example sketch.
Don't sweat it. The originally specified seal might not even have been a good choice and it's a very forgiving situation.
