Product no.: 0285 A11/34
3 screw mainshaft bearing securing plate, to fit all Model 30 and Model 40 International (and CS1/CJ) engines. This pressed steel plate was used to retain the main bearings and ensure they did not 'walk' under heavy use. The plate was secured by 3 screws (sold seperately), which were soldered to the plate after tightening, to ensure they do not come lose. This plate is copied from an original item. Note: this plate fits all International crankcases after approximately 1932. before that time a shallower plate was used. If you are not sure - measure the lip of the main bearing housing ( see second photo), if it sits approx. 0.225" above the crankcase wall it is for this plate. If it measures approximately 0.175" above crankcase - then the very early securing plate is required (see Item no 0287). The late type crankcase is on the left in the 3rd photo
