If you are looking for external crankshaft measurements I don't know if the service manual would have them by application.

Darn it...well thanks guys, was hoping it would be the larger diameter, i guess WH used the 1.125 with a sleeve, and some others used the 1.250.

None used 1.250" as far as I know. The hardened bearing races used are 1" ID for the B&S engines and Kohler 8hp and smaller plus a few early 10hp Kohlers.

All others have 1-1/8" ID.

My 12hp Kohler has the hardened race, all WH with the mechanical clutch did i thought.

Clutch ID is 1.435" so yeah its quite a bit larger.  They call it 1 7/16.

Sounds like the size of a Kohler Command Pro 20 / 22 hp that they used in Toro WH XI machines. I might be able to check one tomorrow.
