Sundstrand Series 40 Swashplate Journal Bearing
They are changing the way the bearing is on the front cover. It was just on the front cover and now it has a flanged pin to hold it in place on the front cover. The hole in the bearing is bigger and the OD in the pin is also. You can put the new pin on older units. But the older pins will no longer be available.
To put in the new bearing and pin, put the pin thru the hole in the bearing in thru the running surface side. Make sure to seat the pin in the hole of the front cover. The head of the pin needs to below the surface so the swashplate want have contact with it. The swashplate bearing want change.
