Can I install a crankshaft for a Briggs & Stratton model 123K02-240 engine in a B&S model 123K02-0615 engine and have good operation and performance?

If the journal sizes, (bearing fits and connecting rod fit) on the cranks are the same size, it will work.

Rick, that is exactly want I want to do. Put a Type 0240 crank in a type 0615 engine. Are they internally interchangeable and would there any mechanical or performance problems with doing this? I want to convert a B&S lawn mower engine (0615) to a type 0240 engine and put it on a vac/shredder. They have differrent cranks as far as their output shaftconfigurations but are both are listed for B&S 123K002 engine models. Thanks for your help.

The part numbers for the two crankshafts are different.
Type 0240 uses P/N 694478 Crankshaft, listing for $43.60
Type 0615 uses P/N 691451 Crankshaft, listing for $48.95
I have no reference as to what is difference is between them.
