## ⚙️ Key Features

-   Supersedes 3862421
-   Precision internal spline profile
-   Hardened torque-transmission surface
-   Used in upper-drive shaft and bearing-housing assemblies

## 🔌 Function

Couples the adjoining splined shafts so engine torque is transmitted through the upper drive without rotational slip.

## ⚠️ Common Signs of Failure

-   Spline wear or fretting
-   Clunk during load reversal
-   Red metallic debris in drive oil
-   Loss of drive despite rotating input shaft
-   Sleeve seized to a shaft by corrosion

## 🛠️ Service Notes

-   Standard-length sleeve for the DPH/DPR upper-drive connection — the longer 22098612 sleeve is a different length used only with the 22175328 one-inch extension kit; the two are not interchangeable
-   A sleeve that has stripped or rounded its splines after a grounding or impact event usually means the mating shaft splines are damaged too — inspect both before fitting a replacement
