The units that will utilize this change are M25, M35 & M46
Single and tandem pumps that have SAE A Pad.
The seal is no longer a square cut out, it is a round seal like a doughnut. The sealing properties are the same as the square one, now it will be easier for you to put it together.
When you take off eh pad cover to put in the auxiliary pump, you will need to use an oring to seal that with. It uses just a standard oring and the part number for that is 9004100-1520.
The pad seal part number is 4800482 (old part number 9004375-0024).
