1991-92 AXOD-E Checkball Locations
1991 AXOD-E's were made with either 4 or 5 checkballs in the pump. All 1992 models have 4 checkballs in the pump. All 1991 and 1992 valve bodies have 7 checkballs.
To determine if a 1991 model should use 4 or 5 checkballs, look at the spacer plate. If you have 2 holes in the bathtub shown, then use the 5 checkball arrangement shown in Figure 2. If there is only one hole in the bathtub, use the 4 checkball arrangement in Figure 3.
All 1992 models use 4 checkballs as shown in Figure 4.
NOTE
EVEN THOUGH LATE 1991's AND 1992's BOTH HAVE 4 BALLS, THE PLACEMENT IS DIFFERENT BETWEEN THE YEARS. BE SURE TO INSTALL THE BALLS IN THE PROPER LOCATIONS FOR THE MODEL YEAR YOU ARE WORKING ON.
EARLY 1991 - 5 CHECKBALLS (Figure 2)
LATE 1991 - 4 CHECKBALLS (Figure 3)
1992 - 4 CHECKBALLS (Figure 4)
