192 / 250 GEAR SET MODIFIED FOR B&M DOUBLE ROW BEARINGS [#9369]

These TBS gears are modified for the use on TBS replacement rotors for a B&M Supercharger with 5204 double row front bearings.  They are already modified with .260″ machined off the back bearing contact pad for the extra width of the double row bearing.  This modification is necessary for the proper front cover internal clearance on the B&M supercharger.   The original B&M Superchargers used the same front rotor shafts for both the single and double row bearings.  The difference was in the gears with two different “Pad” thicknesses to work with the different thickness of the bearings.

These gears work on TBS Replacement rotors only and will NOT work on the original B&M rotor set.
