# 21929775 Repair Kit | Genuine Volvo Penta Part

## 🔧 Product Description

A genuine Volvo Penta upper-gear-housing repair package for cone-clutch DPH, DPR and selected DPI sterndrives. The kit services the primary shifting and sealing wear components in the upper housing.

## 🔌 Function

## ⚠️ Common Signs of Failure

-   Drive slips in forward or reverse
-   Delayed, harsh or incomplete engagement
-   Metal or clutch debris in drive oil
-   Oil leakage or water contamination in the upper housing
-   Kit selected for the wrong DPH/DPR revision

## 🛠️ Service Notes

-   Confirm the kit is the one for your unit before starting, and lay the contents out against the parts you remove so nothing is left in the packet
-   Replace every seal, gasket and wearing part the kit supplies, even where the old one still looks serviceable — mixing old and new sealing parts in one joint is the usual reason a repair leaks again
-   Work clean and cap open pipes and ports; most repair kits serve fuel, oil, cooling or hydraulic components where dirt does the damage
-   Check what the kit does not include — bores, sealing faces, threads and shafts — because a kit cannot compensate for a worn housing
-   Assemble in the order and to the tightening figures given in the workshop manual for your engine, then test for leaks and correct operation before returning the engine to service
