Jack's Comments:

This is basic kit you need to rebuild your small bearing Ford Mercury big block FE water pump. The bearing is made with an outside diameter slightly oversized to achieve a tight press fit. You will need a press and the right press accessories to install the seal without damaging it. No instructions included. One rear housing and two mounting gaskets are included in each kit.

NOTE: Please check your pump bearing dimensions against our dimensions pictures before ordering. If the seal looks a little different than yours, it is because it's a new & improved one piece longer-lasting double seal version.
Tip: Use a little Permatex Form-a-Gasket #1 to help seal the water pump bearing and seal to housing.
Tip: Measure your hub and impeller locations before removing.
Tip: Make sure the seal does not make contact with the impeller when installed.  (see Q/A's below for more information)

Check out this YouTube video that shows a tractor water pump being rebuilt with the same type of bearing and seal.

Q: When I installed the impeller it bottomed out on the seal just short of the depth that was required. Does the impeller make contact with the seal? What should I do?
A: No, it should never contact the impeller. Your original pump must have had the old style single seal that is thinner than the double seal that is with our kit. At the shop we handle this putting the impeller in a lathe and removing just enough of the cast impeller so it doesn't touch the seal and still installs at the correct depth. This will not affect the impeller performance. It's also OK to not have the shaft install completely into the impeller hub. As long as its at least 3/4 the way in the impeller hub it will work without any problems.

*MEL 410 Customer Notes:
I just used the 'small bearing FE' kit (WP1022-S) to rebuild the water pump on my MEL 410 engine. If you are willing to cut off the shaft at the impeller end to the original MEL length, and make a cover gasket, the rest is a perfect fit. ~Ken
