When servicing a hub or replacing cones we recommend that you always replace the balls.

The HB-7800 was made in two configurations - the A type used 3/16" balls x 28 (14 per side) but the B-type used a ball retainer (Y25R98080) that we do not stock.

For this quality of hub we recommend you use Grade 5 balls (very high quality).
