V2203 Connecting Rod Bushing supports smooth piston-pin movement for diesel rebuilding, B2B excavator engine parts sourcing, and wholesale repair stock.
The V2203 Connecting Rod Bushing YNF18981 is installed in the small-end bore of a compatible connecting rod, where a bearing surface is provided for the piston pin. During engine operation, repeated reciprocating loads are transferred between the piston, piston pin, and connecting rod, making correct bushing clearance important for smooth movement and reliable engine rebuilding.
This component may also be called a connecting rod small-end bushing, piston pin bushing, con rod bush, or connecting rod copper sleeve. When excessive wear, scoring, looseness, or unsuitable piston-pin clearance is found during overhaul, the bushing may need to be renewed.
For B2B buyers, YNF18981 should be confirmed by V2203 engine model, connecting rod configuration, inside diameter, outside diameter, bushing width, and existing-part photos before quantity purchasing. Accurate matching helps rebuilders reduce machining problems, incorrect stock, and repeated international freight.

YNF Machinery supplies V2203 connecting rod bushings and related diesel engine overhaul components for engine rebuilders, repair workshops, machinery dealers, wholesalers, and international importers.
The YNF18981 copper bushing is a small internal engine component, but correct dimensional matching is important because piston-pin clearance and connecting-rod fit can directly affect rebuilding quality.
Professional buyers can provide the V2203 engine model, required quantity, bushing inside diameter, outside diameter, width, connecting-rod photos, and existing-bushing measurements for confirmation.
V2203 pistons, piston pins, piston rings, connecting rods, rod bearings, main bearings, cylinder liners, and gasket kits can also be included in the same inquiry, helping B2B buyers build a more complete engine overhaul order.
