Thread: 4hp22 pump gear alignment question

While removing the pump from the intermediate plate the centre small pump gear fell out.

I have the dot on the outer gear at 12 oclock.
Thanks
Michael.

The marks on the gears facing up, with the 2 marked teeth meshing the mark on the inner gear tooth is on the left of the outer marked tooth.
With the rectangular hole in the body of the pump sitting at 6 o'clock, the marked tooth on the outer ring is at 5 o'clock and the marked tooth on the inner ring is halfway between 5 and 6 o'clock, hope this helps, Regards Frank.
