Description
Overview:
The Big End Bearing R1 (26.75 mm) Under Size is a genuine M.A.G component for the M.A.G 1014 SRL engine, supplied under part code 0529 073. It is a precision-engineered bearing shell made from durable bearing-grade metal, designed to support the crankpin at the connecting rod big end. The R1 undersize dimension of 26.75 mm suits engines where the crankshaft journal has been reground and requires a matching undersize bearing to restore correct oil clearance. Built for reliable service in construction and garden machinery powered by the M.A.G 1014 SRL, it helps maintain smooth, efficient operation under continuous load. This is unused old stock (vintage) and may show light tarnishing or storage marks that do not affect performance. Genuine M.A.G part for assured fit and function.
Key Features:
- Genuine M.A.G bearing for the 1014 SRL engine for straightforward, correct fitment
- R1 undersize specification (26.75 mm) to suit reground crank journals and restore proper oil film
- Precision-ground surfaces for consistent oil clearance and reduced friction
- Durable bearing construction for wear resistance under heavy-duty use
- Stable performance at operating temperature and load typical of site and garden machinery
- Unused old stock: may have minor cosmetic tarnish from storage with no impact on service life
- Suitable for routine overhauls and repairs to prevent knock and premature crank/rod wear
- Supports smooth running, improved longevity, and reduced risk of seizure when installed correctly
Typical Applications:
Used during engine rebuilds and repairs on M.A.G 1014 SRL power units in equipment such as compactors, mixers, pumps, generators, and garden machines. Ideal when a crankshaft has been reground and an undersize big-end shell is required to achieve the correct clearance and reliable lubrication.
