21161942 Gasket | Genuine Volvo Penta Part

🔧 Product Description

A genuine sealing gasket used in the D13 electronic inboard steering-gear tube and sensor assembly. It seals the specified steering housing/tube joint and is not an engine lubrication or cooling gasket. Its openings and compressed thickness are matched to the steering unit components.

🚤 Compatibility

• Engine Family: D
• HP Range: 110-435 HP

Full model list at the end of this description.

⚙️ Key Features

• Steering-gear joint-specific gasket profile
• Confirmed on D13B-N MH and D13C6-A MP steering diagrams
• Seals around the tube/sensor housing interface
• Material selected for hydraulic-steering fluid exposure
• Must be installed with the correct tube, O-ring and sensor arrangement
• Engine type: D13 electronic inboard steering-gear installation

🔌 Function

Seals the assigned electronic steering-gear joint so hydraulic pressure is retained and contamination cannot enter the mechanism.

⚠️ Common Signs of Failure

• Oil, coolant, hydraulic fluid or gas leakage
• Hardened, flattened, cracked or extruded sealing material
• Damaged thread or mating surface
• Recurring leakage after incorrect torque or surface preparation

🛠️ Service Notes

• Fit a new gasket every time the joint is disturbed — a gasket takes a permanent set once it has been torqued and will not seal reliably a second time
• Scrape both faces back to clean bare metal, keeping the blade at a shallow angle so it lifts the old material without gouging the surface, and use a plastic scraper on aluminium castings
• Check the faces for flatness, cracks and corrosion pitting, and make sure no old gasket, carbon or hardened sealant is left in the corners or around the bolt holes
• Fit the gasket dry unless the workshop manual for your engine calls for a sealant, and then only the type it specifies — surplus sealant squeezes out into oil, coolant and fuel passages
• Draw the fasteners down progressively in the sequence and to the torque given in the manual for your engine, and recheck after the first heat cycle where the manual asks for it
