4G32, 4G33 and 4G37 crankshaft interchange
Posted: Thu Nov 10, 2011 3:45 am
Hi, I have a 4g32 belt SOHC engine from a Bobcat that spun a rod bearing and chewed up the crankshaft. I've searched all over the internet for a 4g32 crank to no avail (I live in the US where the 4g32 is not available). What I have come across is that the block to the 4g37, 4g33 are the same as the 4g32 only with different bores. My question is, would the crankshafts be interchangeable between these engines since the stroke is the same? My crank from the 4g32 has the 5 bolt holes for the flywheel like the 4g33 and 4g37. Would a crank kit for say a 1993 Eclipse with a 4g37 fit a 4g32 engine block? Thank you for any help, I greatly appreciate it.
