This exact engine or shortblock isn't available for this. One of the original spec numbers was 60150. This tractor used a 1-1/8" x 3-3/4" shaft. If you use the short block # 4552239, the exhaust port would be 1-1/4" instead of 1". The k321-60221 and the K341-71179 will have the same mounting and the same shaft. Parts should be interchangeable.
