Description
Overview:
This Big End Bearing (Shells) pair is a genuine Hatz component for the 1B20 and 1B30 single-cylinder diesel engines. Supplied as two semi-circular shells, it supports the crankshaft journal at the connecting rod, maintaining the correct running clearance and reducing metal-to-metal contact. Manufactured to Hatz OEM standards (MPN 01575700), the shells are steel-backed with an anti-friction bearing alloy overlay for durability and stable oil film formation. Correctly fitted big end shells help minimise wear, reduce frictional losses, and maintain consistent oil pressure, which supports smooth engine operation and long service life in compact plant and machinery commonly used on site and in workshops. Genuine Hatz parts ensure dimensional accuracy and material quality for reliable fit and function.
