17468786 O-Ring | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta o-ring is a machined lubrication-system filter and distribution housing used in the oil-filter housing sealing joint. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it seals the plug/bypass-valve area of the alternative-mounting oil-filter housing. Selection must be confirmed by OEM part number 17468786, the exact engine/product model, serial number and installed configuration.

🚤 Compatibility

• Engine Family: D, TAD, TWD

🔌 Function

Seals the plug/bypass-valve area of the alternative-mounting oil-filter housing. Clean all oil galleries and sealing faces, renew filters, plugs, O-rings and bypass components as required, prime the lubrication system and verify hot oil pressure and leakage after installation.

⚠️ Common Signs of Failure

• Fluid weeping, seeping or dripping at the joint
• Hardening, cracking or loss of elasticity on removal
• Flattening or permanent set so the ring no longer springs back
• Swelling or chemical attack from the fluid it seals
• Nicks, cuts or twisting from incorrect installation

🛠️ Service Notes

• Always fit a new O-ring — never refit one that has been removed, as it has already taken a set in its groove
• Clean the groove and both sealing faces and check them for nicks, scoring and corrosion pitting; a damaged groove will leak however good the new seal is
• Smear the ring with a little clean lubricant compatible with the fluid it seals, then roll it into place by hand so it sits untwisted and fully in its groove
• Never lever an O-ring over a sharp edge or thread with a screwdriver; use a blunt plastic tool and protect any edge the ring has to pass
• Assemble the joint squarely and tighten to the figure and sequence given in the workshop manual for your engine — over-tightening extrudes the ring and causes the very leak you were curing
