Rear Main Bearing Set Application

This Fel-Pro BS40708 rear main bearing set is an engine tool designed for crankshaft support during rebuilds. Mechanics and engine builders use it to restore proper clearances on the rear main journal. The transparent colour aids visual inspection before installation. It fits the specific applications listed for this part number.

Sustained Load Durability

Under continuous engine operation the bearing surfaces maintain oil film integrity to resist wear. The materials are selected to handle the constant rotational forces and thermal cycles present at the rear main position. Consistent performance relies on correct journal preparation and torque procedure. This set is built for the demands of daily driving and extended service intervals.

Part Number BS40708 Fitment

The BS40708 designation is the single specification that confirms whether this set matches your engine. Verify the part number against your vehicle service manual or the manufacturer catalogue before ordering. An incorrect match will prevent proper seating and cause oil leaks or engine damage. No other dimension or feature overrides this identification.

Questions about this item

How much heat or noise does the Fel-Pro BS40708 rear main bearing set generate during continuous engine operation?

The bearing set is a passive metal component; it creates no heat or noise of its own. Engine heat and sound come from combustion and rotating assemblies, not from the bearings themselves.

What existing engine components must already be in place for the Fel-Pro BS40708 rear main bearing set to install correctly?

You need a compatible crankshaft journal, a clean block saddle and main-cap surfaces, plus the correct torque specifications for the main-cap bolts. The bearings fit between those mating surfaces.

Will the Fel-Pro BS40708 rear main bearing set work with an older crankshaft that has been reground to an undersize?

This set is manufactured to standard size. If the crankshaft has been reground, you must select the matching undersize bearing set instead of this standard part.
