Have this engine that was in an XL when I acquired it. Put a running OH140 in as the OH160 has a bad alternator, by PO. Want to get this OH160 running but cannot find the right parts break down to get the correct part number for the alternator. None of the service manual I have or looked at have a parts break down. Numbers are: OH160 170133F Spec is 9352F . This is a horizontal shaft engine. Any help is appreciated.
