The Berkeley M10210 lip oil seal is a replacement bearing-frame seal measuring 2.250 in. ID x 3.005 in. OD x 0.375 in. wide. On the B4JRMBHS B69743 configuration below, it occupies the outer-bearing-cap seal position, item 51A.
Use M10210 when that specific oil seal is required. The pump also uses a different oil seal at item 51B and a separate mechanical shaft seal, so identifying the service location is essential before choosing replacement parts.
The three dimensions support an initial comparison with the removed seal, while the exact part number distinguishes the correct component from nearby seals. This item is the lip oil seal only, not the outer bearing cap or a complete mechanical shaft-seal assembly.
