I'm replacing some bearings and, as I removed the motor, I was looking at the seal in the head and noticed the V edges of the seal were sitting
well above where they would make contact with the power input shaft.
The seal I removed was a 35x62x12.
I'm thinking I should use a 35x62x10.
Can anyone confirm what that seal should be please?

I should add mine is an original Industrial Hobbies from Aaron if that makes any difference.
