Sundstrand Series 40 Axial Piston Pump – Feedback Pin
Posted by Tammy Soper on
They have made the feedback pin longer on the swashplate assy. Now the pin is .535 inches long from the .340 inches it was.
When replacing any new pins going forward on repair jobs, the old one will no longer be available. The slot in the pin needs to face rotating kit or 160 degrees away from it.
If yours is an older unit you will need to use a control sleeve.
slotted pin………………..old p/n 9004700-2512………new p/n 5000381
pin length…………………………………075″………………….9375″
model numbers affected…………..All M46-2xxx and M91-46xx
