Alternator Drive Belt 129612-42290E for Yanmar 2YM15 3YM20 3YM30 Marine Diesel Engine
Product Overview
Alternator belt for Yanmar 2YM15, 3YM20 and 3YM30 marine diesel engines, replacing Yanmar 129612-42290E and supplied as 1 x belt. It drives the alternator from the crankshaft pulley, so a worn belt shows up as a slipping squeal on start-up, a battery that slowly goes flat, or visible cracking and glazing on the belt ribs. Sourced from Taiwan.
