Alright, below are the measurements I have which I obtained from the stocked parts we have:

E103497 Valve plate:

3.5" diagonally from mounting hole to mounting hole
OD of where round gasket fits into valve plate 3"

E106122 Piston Assby:

Cylinder ID 2.5"
Connecting rod ID 1.375"
Top of piston to center of connecting rod hole 4.5"

All measurements are nominal.

If you can match up your measurements with the above, I think that will tell us if these parts are identical or not!

I understand! I'll look out for your reply Cedric.

Great to hear

The E103497 Valve Plate Assy can be found on the below page:

...and the E106122 Piston/Cylinder Kit can be found on the below page:

The manufacturer only sells the Valve Plate and Piston Kit in two separate kits, so this would be the only option when needing to replace both components.

Let me know if you have any other questions at all and I'll try to assist any way I can.
