Champion ZR154 Low Pressure Piston With Pin For R10D R15B And R30D Pumps

Champion ZR154 Low Pressure Piston With Pin is the genuine replacement kit for Champion R-series air compressors, designed to restore the low‑pressure cylinder in models R10D, R15B, and R30D. In Champion service literature this part is listed as the “Low pressure piston with pin” (ZR154) and is described as including the piston assembly with its pin and related hardware (items 43 and 44) required for proper fitment. The kit is intended to replace worn or damaged low‑pressure components to revive correct piston travel and compression in the first stage of these two‑stage pumps. Compatible with R10D, R15B, and R30D pumps, ZR154 is typically used during maintenance and repair of Champion R‑series units to maintain the original operating characteristics of the compressor system. When selecting this part, verify that your unit is a Champion R‑series model and specifically one of the R10D, R15B, or R30D configurations to ensure proper compatibility and seal seating in the low‑pressure cylinder.
