Kohler MV16, MV18, MV20 Twin-Cylinder Engine 1986-1988 Repair Manual (P/N TP-2289-A)

• Official Kohler publication TP-2289-A covering the 1986–1988 MV16, MV18, and MV20 twin-cylinder engines
• 105 pages of original manufacturer documentation focused on the Magnum-series build
• Provides 49 exploded-view diagrams and 6 system schematics for the carburetor, ignition, and fuel pump assemblies
• Details factory clearances, engine identification, and technical overhaul parameters

Service and System Overview

This reference manual provides precise technical data for Kohler's twin-cylinder architecture. It outlines periodic maintenance schedules directly from the manufacturer. You get direct access to troubleshooting steps for non-crank conditions, ignition failures, and fuel system calibration. The document maps out the lubrication system in detail. It specifically covers pump rotor measurements and wear limits. Electrical diagnostics are fully documented, featuring wiring diagrams for 15-amp and 25-amp regulated battery charging systems. Servicing these components exposes mechanics to high-voltage circuits and flammable fumes. Always disconnect the battery and ventilate your workspace before inspecting fuel lines or checking the ignition module.

Specifications and Factory Tolerances

Building an engine requires exact numbers. The text lists torque specifications for components threading into iron, steel, and aluminum, including head bolts and oil drain plugs. Visual reference charts guide the reassembly process. They show exactly where to apply crankcase sealant and lay out the precise torque sequence for the cylinder heads.

Tolerance tables provide the baseline numbers for the Magnum series. The compression ratio for the MV16 is documented at 5.8:1. Valve specification charts set the intake valve clearance between 0.003 and 0.006 inches. For the ignition system, the module air gap across the MV16, MV18, and MV20 models is firmly established at 0.008 to 0.012 inches.
