VOLVO B16 A and B16B Engine Rebuild Manual: A Comprehensive Guide

The VOLVO B16 A and B16B engines, known for their robustness, may require a rebuild after years of service. This manual provides a general description and repair instructions to guide you through the process, covering everything from engine removal and dismantling to careful assembly and troubleshooting.

General Description and Specifications:

Before starting any work, familiarize yourself with the engine's specifications. Knowing the tolerances and torque values is critical for a successful rebuild. The B16 engine is a gasoline engine known for its reliability. Understanding its design is the first step in any repair.

Removing the Engine:

The first step involves safely removing the engine from the vehicle. This requires disconnecting all hoses, wiring, and linkages. Thoroughly document each connection to ease the installation process.

Dismantling the Engine:

With the engine on a stand, begin dismantling it systematically. This involves removing components like the oil sump, cylinder head, and internal parts. Keep track of each piece and its original location.

Critical Components and Repair Instructions:

Cylinder Head and Valves: This section covers valve grinding and decarbonizing. Pay close attention to valve seat condition and valve guide wear.
Cylinder Block: Inspect the cylinder bores for wear or damage. Honing or reboring might be necessary.
Pistons, Piston Rings, and Gudgeon Pins: Check for piston wear and replace piston rings. Ensure proper gudgeon pin fit.
Connecting Rods: Inspect for bending or cracks. Verify bearing journal dimensions.
Crankshaft: Have the crankshaft checked for straightness and journal wear. Polishing or grinding may be required. Replacing the oil seal and addressing the timing gear casing are essential.

Assembling the Engine:

Assembly is the reverse of dismantling, but with careful attention to detail. Use new gaskets and seals throughout. Torque all fasteners to the specified values and lubricate all moving parts. Correct timing gear installation is crucial for proper engine operation. Ensure the pilot bearing for the input shaft is in good condition.

Lubricating and Fuel Systems:

Lubricating System: Understand the engine's lubrication system and inspect the oil pump for wear.
Fuel System: The fuel system, with options like Zenith-Stromberg or SU carburetors, requires careful attention. Rebuild or replace components as needed. Clean the air cleaners and test the fuel pump. Inspect the Flap housing for the air preheating unit.

Cooling System:

Cooling System: The cooling system's effectiveness is vital. Inspect the water pump, thermostat, and radiator.

Final Steps and Troubleshooting:

After installing the engine, carefully check all connections and fluids. Start the engine and monitor for any leaks or unusual noises. In case of problems, the fault tracing section will guide you to identify and resolve issues.

By following these guidelines, you can successfully rebuild your VOLVO B16 A or B16B engine, restoring its performance and extending its lifespan. Remember to consult the original Volvo repair manual for specific details related to your engine model.
