Exhaust Tappet (RE15179)
- Rolls-Royce Silver Dawn & Silver Wraith
- Bentley MK VI & R-Type
This tappet is from the engine section in the Rolls-Royce & Bentley parts catalogues for models built between 1946 to 1955.
Hydraulic tappets are tappets that contain a small hydraulic piston, pressurised by the engine's lubricating oil supply. Although the piston does not move appreciably or frequently, it acts as a hydraulic spring that automatically adjusts the tappet clearance according to the oil pressure. This makes the valve actuation self-adjusting and there is no need to adjust the rockers. Hydraulic tappets depend on a supply of clean oil at the appropriate pressure. When starting a cold engine, with low oil pressure, hydraulic tappets are often noisy for a few seconds, until they position themselves correctly.
