Overview
Overview
HP-CB-CB20 is the 20% Clark Pump center block. The factory guide shows two piston-rod passages, compared with the single-rod arrangement in the 7% and 10% pumps.
The 20% pump uses two rods of the 10% rod size, but that shared rod size does not make the 10% center block interchangeable. The block must accommodate both rods.
This listing is for the center block without inserts, as specified by the catalog.
