Enginetech BC1022.25 0.25mm Undersize Main Bearing Set for 2006-2020 Honda 1.8L I4 – Complete OEM-Spec Main Bearing Set

Description

Enginetech BC1022.25 is a 0.25mm undersize main bearing set for 2006-2020 Honda 1.8LI4 engines.

Important Notes:

• Sized for crankshaft main journals machined .25mm undersize. Measure journal diameter before installation – installing on the wrong journal size will cause immediate clearance failure.
• Always replace main bearings as a complete set. Never mix new bearings with used bearings – uneven wear and clearance differences will cause premature failure.

Complete main bearing set covering all main journals for the I4 application – one set required per engine.

Fitment:

2006-2011 Honda Civic 1.8L Noneci I4; 2012-2015 Honda Civic 1.8L Noneci I4; 2016-2020 Honda HR-V 1.8L Noneci I4

Enginetech main bearings are engineered to OEM specifications, drawing on over 40 years of engine rebuilding expertise to deliver the precise clearance, crush, and eccentricity required for long-term durability under both stock and moderate-performance loads. Each set is application-specific: materials, wall thickness, oil clearance, and surface finish are all matched to the crankshaft main journal geometry and operating loads of the engine family it serves. Main bearings are a wear component and must be selected to match the crankshaft main journal size – bearings sized for standard journals will not seat correctly on undersize-machined journals and vice versa, so verify your journal measurement with a precision micrometer before ordering or installing. Always replace main bearings as a complete set. Mixing new bearings with used bearings produces uneven oil clearance across the crankshaft and accelerates wear on the freshly installed bearings – the small cost of a complete set is insurance against premature failure on the bearings you just paid to install. Enginetech documents every set with clear application-specific notes, journal-size designation, and cross-references so the right part lands on the bench the first time.
