Ariens Engine Blocks / Crankcases
To match the correct engine block or crankcase, check the engine model details or an existing part number before ordering, as these castings vary between Ariens engine applications. Garden Tractor Spares lists genuine OEM replacements for selected Ariens garden machinery, helping you identify the right component for a proper repair. These are major engine housings, so confirming the exact specification from the machine and engine identification numbers is essential.

Frequently Asked Questions
Do these castings fit by engine number?
Yes, engine blocks, crankcases and sump components in this category are matched to the engine fitted to your Ariens machine. Check the engine's identification numbers before ordering, as these major castings are engine-specific rather than chosen by appearance alone.
Can I choose a sump from the old casting?
No, the old casting is not the best guide for selecting a replacement. The correct sump is identified by the engine's identification numbers so it matches the exact engine specification fitted to your Ariens machine.
Should assembly parts match the same engine?
Yes, any sealing parts used when rebuilding should be selected to suit the same engine identification numbers as the block or crankcase. Keeping everything matched to that exact engine helps the assembly correspond with the casting you are fitting.
