I'm trying to establish the right nomenclature for the gear I need to replace. Got the general data but there seem to be a set of letters that are not specifically defined in the manufacturers sites that I have looked at. MMSG SMSG MMSA (B) MMS - SMS
The gear I have to replace was pressed on to the shaft with a key. Shaft is 12mm and the key measures .157 wide. Can someone clarify the meaning of the various letter description above? It is a 20 tooth right hand etc info OK but the shaft info is what is in question. Thanks. ...lew...
