fixing the bobcat 742 engine
once the motor came out i was able to see just how bad the damage was. the crack propagated all the way up the back of the block, so it didnt take long to realize it would need at least a block and a rod. at this point it makes a lot more sense to explore more rugged options than a tiny ford four cylinder designed in the 60s.
i did take a look at what it would take to use some other powerplant, and it appears pretty straight forward. the connection to the rest of the bobcat is 6 or 8 bolts to a fan that links to the pumps via a u-jointed splined shaft, so even alignment shouldnt be extremely critical.
