Exhaust manifold bolt M10x57 320/06045 JCB 444, genuine

Engine bolts hold together parts that work under high temperature, vibration and changing loads. In joints such as the crankshaft pulley, flywheel, connecting rod and rocker shaft, the correct bolt preload stops the parts from shifting and protects the gears, seals and bearings. Manifold and housing bolts expand and contract as they heat and cool, and a bolt that is not tightened correctly lets gas or fluid leak past the gasket.
