Some of you may recognize that this thread was posted earlier. Marc Levenson- Melev here on RC, sent me some much better photos and I am updating this thread using his photos.
We will start with the 6100.60 drive unit. This drive unit is used on all 6000/6100 and 6200 and wavebox pumps made prior to January, 2006. This drive unit is the same as the 6080.60 used on the current 6060 and 6080 pumps with the exception of the 7400.610 o ring.
Here we see the complete assembled unit removed, the bush bearing is not shown in the photo, the bush bearing is the collar that is around the impeller well.-
In this photo we see the upper bearing, this part is the most frequent cause of a problem, it can become cemented to the magnetic rotor with lime, the magnet should spin freely on the bearing. The bearing can be removed with a screw (see manual) a pair of very small needle nose, or a pick if it is at the bottom of the impeller well. If it is stuck to the rotor, gently pry it off with a slotted screwdriver.
In this photo we see the drive unit fully dissassembled. It should be cleaned with vinegar and a brush-
This photo gives a detail of the 7400.610 o ring, this is the only difference between a 6080.60 and a 6100.60, it restricts the movement of the brakes which are not required on the electronic pumps.
In this photo we see the hole in the center of the drive unit, it is critical that this be thoroughly cleaned to get the full service life, also be sure the well the drive unit is inside is also cleaned, just use vinegar and a brush for this-
