**NLA** Type 4 Con Rod Bearing Set - 1700cc, 1800cc (0.75mm)

This complete connecting rod (big end) bearing set is designed for Volkswagen Type 4 air-cooled engines in 1700cc and 1800cc capacities, as fitted to Baywindow Buses from 1972 to 1975. It is also suitable for Porsche 914 models using equivalent Type 4 engines.

Connecting rod bearings form the critical interface between the crankshaft journals and the connecting rods. They provide a precision bearing surface that supports high engine loads while allowing smooth crankshaft rotation. Correct bearing sizing is essential for maintaining oil pressure, minimising friction, and preventing crankshaft or rod damage.

This bearing set is manufactured to tight tolerances to ensure accurate oil clearance when matched correctly to your crankshaft journal size. It is ideal for engine rebuilds, restorations, or crankshaft regrinding work, where selecting the correct undersize bearing is critical for long-term reliability.

Supplied as a set of 8 bearing shells, this kit is sufficient to rebuild one complete engine (four connecting rods).
