Description
Overview:
This is a genuine JAP piston ring set sized oversize +0.020 in (approximately 0.51 mm) for JAP Model 34 engines. The rings are precision-finished metal components designed to restore correct sealing between piston and cylinder after a rebore, helping to recover compression and control oil. Suitable for rebuilding vintage stationary engines commonly found in older construction, agricultural and garden machines, the set supports reliable running and easier starting when the cylinder has been machined. Supplied as an Unused Old Stock vintage part, so light tarnish or storage marks may be present, but the rings are unused. OEM reference: JAP MOD 34CC/020. A practical choice for engine restorers, workshops and experienced DIY users working on JAP Model 34 equipment.
Key Features:
- Genuine JAP part (OEM JAP MOD 34CC/020) for assured compatibility with Model 34 engines
- Oversize +0.020 in (approx. 0.51 mm) to suit re-bored cylinders and restore correct fit
- Helps recover compression, reduce blow-by and oil consumption, and improve starting performance
- Durable, heat-resistant ring construction for long service in air-cooled stationary engines
- Designed to meet original build tolerances for dependable sealing when installed correctly
- Suitable for workshop or competent DIY fitting; check ring end-gap and orientation during install
- Unused Old Stock: expect cosmetic ageing from storage, not affecting function
- Supports smoother running and more stable idle on well-rebuilt JAP Model 34 engines
Typical Applications:
Engine rebuilds and overhauls of JAP Model 34 units used in vintage construction and garden machinery such as compactors/rammers, small cement mixers, water pumps, generators, rotavators and similar equipment. Ideal when cylinders have been re-bored to +0.020 in (approx. 0.51 mm) and new rings are required to achieve proper sealing and reliability.
