Replacement engine

Hello all,

I have a 2011 Craftsman riding lawnmower. Model # 917.288570
Engine model 4456 77 2188 G1 (24 HP)
46" cut

Does anyone know the correct replacement engine that would fit this mower?

Thanks for any consideration.

Sam

Thanks again. One quick question maybe you can answer. I measured the crankshaft on the old engine and it was 3" plus or minus a hair. The specs for the new motor state the crankshaft is 3 and 5/32". Does this require a different dual pully for the transmission and mower deck or am I overthinking it?

Looking at the spec's, they all seem to have the crank shaft end.
 
I'd pull your and bring it down to store to match up
