Volvo Penta D2-40 Rebuild Kit – Fits D2-40F, D2-40B

Description

Volvo Penta D2-40 Rebuild Kit – Fits D2-40F, D2-40B

This kit covers the Volvo Penta D2-40 marine diesel engine, including the D2-40F and D2-40B variants — installed across many different boat manufacturers over the years, so the make of your boat matters less here than the exact engine code and serial number stamped on the block.

It includes the core rebuild components: standard-bore pistons, cylinder liners, bearings, and a full gasket set. Volvo Penta issued the D2-40 under more than one internal engine code during production, so confirm your engine’s exact code and serial number before ordering to make sure bearing and piston sizing matches your engine.

What’s included:

• Full gasket kit
• Cylinder liners, semi-finished (set)
• Standard-size pistons (set)
• Piston pins and snap rings (set)
• Rod bushings (set)
• Standard-size piston rings (set)
• Main bearings, standard size (set)
• Rod bearings, standard size (set)
• Thrust washers, standard size (set)
• Intake/exhaust valves (set)
• Valve guides (set)
• Intake/exhaust valve seats (set)

A Volvo Penta D2-40 rebuild kit gives you everything needed to bring a worn marine diesel engine back to working condition in a single order, rather than sourcing pistons, liners, bearings, and gaskets separately from different suppliers. This Volvo Penta D2-40 rebuild kit is built for the D2-40 engine family, including the D2-40F and D2-40B variants, and covers both the bottom end and top end of the engine — the two halves of any full engine rebuild.

On the bottom end, the kit includes standard-bore pistons, semi-finished cylinder liners, piston pins, snap rings, and a matched piston ring set — the core components that wear down as a marine diesel accumulates running hours. Alongside these, you get a full set of main bearings and rod bearings, plus thrust washers to control crankshaft end-play. Together, these components address the most common causes of lost compression, oil consumption, and knocking noises in an aging D2-40: worn cylinder walls, scored pistons, and bearing clearance that’s opened up beyond spec.

On the top end, the Volvo Penta D2-40 rebuild kit covers the valve train — intake and exhaust valves, valve guides, and valve seats — so the cylinder head can be reconditioned as part of the same rebuild rather than as a separate project later. A complete overhaul gasket set rounds out the kit, covering the head gasket and the smaller seals that should always be replaced, not reused, whenever an engine is opened up.

The Volvo Penta D2-40 was installed across a wide range of boats from different manufacturers over its production run, so unlike a car or construction engine, boat brand and model aren’t reliable indicators of fitment here. What matters is your engine’s specific code and serial number, stamped on the engine block or data plate. Volvo Penta produced the D2-40 under more than one internal engine code during its run, and bearing or piston sizing can differ between them — so before ordering, confirm your exact engine code and serial number with us to make sure this kit matches your block, not just the D2-40 name.

Whether you’re dealing with a tired sailboat auxiliary engine, a small motor cruiser, or another vessel running a D2-40, D2-40F, or D2-40B, this kit is built to support a full rebuild rather than a partial fix — pistons, liners, bearings, valve-train components, and gaskets together, in the quantities a complete overhaul actually requires. That’s the difference between an overhaul kit and a piston-only or gasket-only kit: this one is meant to take you from teardown to reassembly without a second order mid-project.
