0041412 Bearing assy, pinion shaft +.0002"

This pinion shaft bearing assembly from Samwel is an oversized option, measuring +.0002" over standard. It is designed for the right side case of 1937 to 1973 45 cubic inch Sidevalve models. Replacing OEM 24671-37, this assembly is crucial for mechanics performing a precision bottom-end rebuild where the shaft or race requires a slightly larger bearing to achieve the perfect clearance. Samwel’s attention to detail ensures that these vintage bearings meet the exacting standards required for long-term engine reliability. Proper pinion shaft support is vital for maintaining oil pressure and overall engine smoothness in your classic flathead.
