21189667 Timing Gear Casing | Genuine Volvo Penta Part

🔧 Product Description

Genuine front timing-gear casing used on Volvo Penta D1-13F and D1-20F marine diesel engines. The casing supports and encloses the timing gears and provides the mounting and sealing surfaces for the front plate, cover and shaft seals.

🚤 Compatibility

Typically suits:

• Volvo Penta D1-13F
• Volvo Penta D1-20F

• Engine Family: D
• HP Range: 13-20 HP

⚙️ Key Features

• Confirmed D1-13F and D1-20F applications
• Supports and encloses the timing gear train
• Factory-machined shaft, cover and gasket surfaces
• Correct oil passages and mounting points
• Supplied as the casing only, not a complete timing kit

🔌 Function

The casing aligns and encloses the timing gears, retains lubricating oil and supports the front engine covers and seals.

⚠️ Common Signs of Failure

• Oil leakage from the casing joint
• Cracked casting
• Damaged bearing or seal bore
• Distorted gasket surface
• Timing-gear misalignment or noise

🛠️ Service Notes

• Clean both joint faces back to bare metal without scoring them, and remove all old gasket, sealant and debris from the block face, the sump joint and the bolt holes
• Use the gasket and the sealant type the manual specifies, applying sealant sparingly at the corners and joint lines — excess squeezes inside and can block an oil way
• Where the casing carries the front crankshaft seal, check the seal bore for wear and fit the seal to the specified depth, at the stage in the sequence the manual directs
• Centre the casing on the crankshaft before pulling it down, using the alignment tool or method the manual gives, or the front seal will run off-centre and leak
• Fit all fasteners loosely first, then tighten in the sequence and to the figures in the manual for your engine, and refit the pulley, damper and drive belt as specified
