Description
Overview:
The Piston Ring Set Standard Size to fit Petters PAZ Single Cylinder Diesel Engine (391460) is a genuine Lister Petter service part for restoring correct cylinder sealing and oil control. The matched rings are supplied in standard bore size for engines that remain within factory wear limits, helping to recover compression, reduce blow‐by, and cut oil consumption. Precision-made from durable engine-grade ferrous alloy, the set is designed to withstand the high temperatures and pressures typical of diesel operation. Suitable for Petter PAZ engines used in construction plant, agricultural equipment, and stationary machinery, it supports reliable everyday running. This is unused old stock (vintage); minor tarnishing or shelf wear may be visible but does not affect fit or performance. Straightforward to install during routine maintenance or top-end overhauls.
