Important: 422413 is a shared OEM sealing ring used across multiple distinct Volvo Penta assemblies. The required quantity and installation position vary by application — confirm by the exact engine, drive, or transmission parts diagram before ordering.

What This Part Is

The 422413 is a genuine Volvo Penta OEM 11mm sealing ring (catalog designation D=11) used in several different Volvo Penta propulsion, transmission, and engine assemblies. It is not specific to a single location — Volvo Penta uses this same ring in the IPS-A upper gear housing, the HS1A reverse gear assembly, and a range of legacy TD, TID, TWD, and TAD diesel cylinder-head assemblies. The ring should always be selected by OEM part number and diagram position, not by appearance or size alone.

Compatible Applications & Required Quantities

Quantity required varies significantly by application. Always confirm the exact diagram before ordering.

IPS Marine Propulsion

• IPS-A upper gear housing — 6 × 422413 required

HS1A Reverse Gear

• HS1A 1.96 and 2.62 ratio transmission assemblies — 11 × 422413 required
• Also listed as included in the applicable HS1A gasket kit

Legacy Volvo Penta Diesel Cylinder Heads

• TD60 / TID60 (selected cylinder-head assemblies — confirm qty by diagram)
• TD70 / TID70 (selected cylinder-head assemblies — confirm qty by diagram)
• TD100 / TD1010
• TWD1010
• TAD1030 / TWD1031 (commonly 6 per cylinder-head assembly)
• Related Volvo Penta industrial and marine diesel variants

Serial Number Notice

Because 422413 appears in multiple engine families, reverse gears, and propulsion units, fitment must be confirmed by the exact engine model, serial number, and applicable Volvo Penta parts diagram. Do not order by dimension alone — adjacent sealing rings in the same assembly may look similar but have different specifications or groove requirements.

When to Replace

• Ring is flattened, permanently compressed, or has lost its profile
• Ring is cut, cracked, or distorted on inspection
• Ring has hardened with age and no longer seals reliably
• Leakage is present at the sealing location
• Ring was disturbed or removed during housing, cylinder-head, or transmission disassembly

Small OEM sealing rings should not be reused once removed from service — reusing a compressed ring risks a return leak after reassembly.

Installation Notes

• Clean the sealing ring seat and mating surfaces before installation
• Ensure the ring seats correctly in its recess without twisting, pinching, or over-stretching
• Follow the applicable Volvo Penta workshop procedure for the specific assembly — installation method varies between IPS propulsion, HS1A transmission, and cylinder-head applications
• Order the correct quantity for the specific assembly — requirements range from 2 to 11 rings depending on the application

Part Number Cross-Reference

• Current OEM: 422413
• Supersedes: 420225, 422333
• Supersession: 420225 / 422333 → 422413

Technical FAQ

Q: How many sealing rings do I need?
A: It depends entirely on the application. The IPS-A upper gear housing uses 6, the HS1A reverse gear assembly uses 11, and TD/TAD cylinder-head assemblies typically use 2–6 depending on the engine family. Always check the parts diagram for your specific assembly before ordering.

Q: Can I use this ring in both IPS and diesel cylinder-head applications?
A: Yes — 422413 is an OEM part used across both propulsion and diesel engine applications. Confirm by part number and diagram position for each specific assembly.

Q: What supersedes 420225 and 422333?
A: Both 420225 and 422333 have been superseded by 422413. If your older parts manual lists either number, 422413 is the current ordering number.

Parts Desk Insights

Best use case: Order 422413 when servicing an IPS-A upper gear housing, HS1A reverse gear assembly, or a TD/TID/TWD/TAD diesel cylinder head where this sealing ring is called out by diagram position. Because it is a low-cost consumable used in quantity, ordering a small surplus is practical — especially for HS1A transmission overhauls where 11 rings are required per assembly.

Common issues: The most frequent mistake is ordering a single ring when the application requires 6 or 11. Always check the quantity in the parts diagram before ordering. A second common issue is reusing removed rings — a ring that looks undamaged on the bench often leaks once the assembly is back under pressure and temperature. Replace all rings in the affected assembly during any major service.
