Enginetech BB603J040 Connecting Rod Bearing .040 Undersize

The Enginetech BB603J040 connecting rod bearing (also called a rod bearing) is a precision engine bearing for rebuilds on Ford FE-series V8 engines. It sits between the connecting rod and the crankshaft journal. It carries combustion loads and reduces friction at the journal. This part number is the .040 undersize, made for crankshaft journals that have been machined smaller during a rebuild.

Key Features:

• Part number: Enginetech BB603J040
• Size: .040 undersize
• Alloy construction: Enginetech makes its rod bearings from alloys chosen for the application. The materials combine high load capacity with anti-friction properties such as wear resistance, anti-seizure and embeddability.
• Consistent thickness: The bearings are made on modern equipment to hold uniform thickness, which helps maintain proper oil clearances.
• Controlled parting line chamfers: The chamfers are cut at the correct angle to allow proper oil bleed-through without reducing oil pressure.

Enginetech rod bearings are intended to give extra protection and better durability throughout an engine rebuild. Check your crankshaft journal measurements before ordering to confirm the .040 undersize is the right one.
