Description
Overview:
The Cup (Inlet Valve) is a Genuine Lister Petter component for Petter PJ diesel engines. This precision‐machined steel cup sits in the inlet valve assembly to keep parts correctly located and aligned, supporting smooth valve movement and reliable sealing during operation. It helps restore correct breathing, combustion, and starting performance on engines that have suffered wear or damage to the original cup. Suitable for service and overhaul work on the PJ series, including PJ1 and PJ2, this unused old‐stock part may show superficial tarnishing from age, which does not affect function. Built to original specifications, it offers dependable compatibility and longevity when installed to manufacturer guidance and used with clean oil and a sound valve train.
Key Features:
- Genuine Petter/Lister Petter part for assured fit and compatibility on PJ series engines
- Precision steel construction for strength, heat resistance, and long service life
- Restores accurate inlet valve action, helping maintain compression and efficiency
- OEM dimensions to suit the original assembly and clearances
- Straightforward replacement for a worn or damaged inlet valve cup; no modifications required
