The Berkeley S13213 inner bearing cap is a cast iron replacement cap for the inner bearing position on compatible B4ERBMS pumps. It fits both the B73023 clockwise and B73027 counterclockwise configurations.
Select this component by its part number and position in the bearing frame. The inner and outer caps are separate parts, so an outer-cap replacement should not be ordered by appearance alone.
The separate cap lets a repair focus on the affected bearing-frame component. Check the cap seating surfaces, nearby seal and bearing condition before reassembly so the repair addresses the parts that are actually worn or damaged.
| Feature | Benefit |
|---|---|
| Inner bearing position | Matches the required location in the bearing-frame assembly. |
| Separate service component | Replace the cap while retaining a serviceable pump frame. |
| Exact S13213 identification | Select the correct inner cap for the pump being repaired. |
