Spindle Assembly & Individual Component References

If your original mower deck needs a 187281 mandrel housing or 192872 mandrel shaft, replacing the complete compatible 192870 spindle assembly may be a convenient alternative to rebuilding the original spindle from individual components.

Exact Deck Configuration

The 80-DK-016 is designed around a specific AYP-built 42-inch deck architecture:

Because AYP used some of these individual components across multiple deck designs, matching only one part number does not automatically confirm that this complete rebuild kit fits your mower.

Need Idler Pulleys Too?

The 80-DK-016 includes the spindle assemblies, spindle pulleys, blades and deck belt, but does not include the deck idler pulleys.

Some related Green Dade rebuild kits are available with additional deck components. Because idler configurations can vary by mower model, verify your complete model/product number before selecting the more complete kit.

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