Spindle Assembly & Individual Component References

This kit includes 2 complete 192870-style mandrel / spindle assemblies. Original parts diagrams and replacement cross-reference data may also show related complete assemblies or individual spindle components:

If you are searching for an individual spindle component such as the 187281 housing or 192872 shaft, replacing the complete compatible 192870-style spindle assembly may be a convenient alternative to rebuilding the original spindle.

936049
936073

936084

Ariens used multiple deck configurations across the 936-series. Verify the original 197253 / 532197253 belt together with the spindle and pulley configuration before ordering.

Why the Deck Configuration Matters

Several AYP-built 42-inch mower decks use a similar 192870-style spindle assembly but use different spindle pulleys and deck belts. Matching only the spindle number is therefore not enough to identify the correct rebuild kit.

Need Idler Pulleys Too?

The 80-DK-027 includes the spindle assemblies, spindle pulleys, mower blades and deck belt but does not include deck idler pulleys.

If your idler pulleys also need replacement, verify your complete mower model or product number before selecting a more complete deck rebuild kit because idler configurations can vary between models and production years.

Aftermarket replacement parts. Husqvarna, Craftsman, Poulan, Poulan Pro, Ariens, AYP and other brand names, model numbers and OEM part numbers are used for identification and compatibility reference purposes only.
