Honda PC800 Pacific Coast Service Manual 1989–1996 (P/N 61MR506)

The Honda PC800 Pacific Coast service manual (P/N 61MR506) covers 1989–1990 and 1994–1998 models. It identifies changes in bodywork, suspension, and wiring by model year and provides separate evaporative-emissions information for California models.

PDF Bookmarks and Wiring Detail

Page navigation and diagram detail: The PDF has bookmarks labeled by page number and no built-in text search. Small connector labels and wire color codes are best read zoomed in. A few markings on the earlier wiring diagrams remain faint at higher magnification.

The ZIP contains one printable 276-page PDF, including the cover and service-symbol key, plus a text file with an online parts catalog link. The printed service material starts at page 1-3, with gaps at printed pages 2-11 and 10-2.

PC800 Bodywork, Drivetrain, and Electrical Service

This selection of service topics focuses on major repair and diagnostic jobs. The manual also covers oil pump disassembly and cooling fan switch testing.

• Bodywork and engine access: Fairing and frame cover removal, trunk lid and hinge service, release cable adjustment, and removal of the fuel tank, exhaust, heat covers, and subframe.

• Cylinder heads and valvetrain: Hydraulic tappet inspection, bleeding, and shim selection, along with camshaft timing, cam chain inspection, and cylinder and piston service.

• Clutch, transmission, and shaft drive: Clutch hydraulics and shift linkage, crankcase separation and assembly, transmission inspection, output gear setup, and final drive bearing and gear service.

• Suspension and brakes: Front and rear wheel service, fork and anti-dive work, steering stem bearings, rear shocks and swingarm, front hydraulic discs, and rear drum brake repair.

• Carburetion and cooling: Carburetor overhaul and synchronization, U.S. pilot screw and high-altitude adjustments, and radiator, water pump, and thermostat service.

• Electrical diagnosis: Charging-system tests, ignition coil and pulse generator checks, starter and starter clutch service, meter and switch tests, and model-year wiring diagrams.

The manual suits technicians and experienced owners who are comfortable using electrical test equipment and the special tools called out for internal engine and drivetrain work.

Trunk and Panel Access

The Frame Cover Removal Chart and Service Access Guide show which panels come off for a particular job. They help you plan access without disturbing unrelated trim or cable retainers. The trunk section distinguishes the early and later release arrangements, while the Fully Sealed Engine Cover System illustration shows how the heat covers fit around the engine.

Tappets, Bearings, and Gear Setup

The front and rear cylinder head procedures show how to inspect and prime the hydraulic tappets. The manual specifies tappet bleeder 07973-MJ00000 and clutch center holder 07923-MB00000, along with separate tools for fork, steering, bearing, and final drive work. Crankshaft bearing selection uses the recorded bearing codes, and the mainshaft drawings identify gear changes after 1989.

Honda flags the flywheel bolt’s left-hand thread because forcing it in the usual direction can damage the threads. It also warns that torch heat can warp the output gear and final drive housings. The separate Honda Common Service Manual is needed for certain shared procedures, including battery testing and the basic gear tooth contact-pattern check.

California Fuel Routing and Model-Year Wiring

The Carburetor Vacuum Tube Routing diagrams distinguish California and non-California hose layouts. The fuel specifications identify the VDGUA carburetor for California models and the VDGTA for the other configuration. The cooling chapter covers in-frame cooling-system service and warns about hot coolant under pressure.

The charging flowchart separates current leakage, regulator and rectifier faults, and alternator coil faults. The electrical chapters also cover fuel pump, cutoff relay, and fuel level sensor checks. The Self-Canceling Turn Signal System Diagram and related tests apply to 1989–1990 and 1994–1996. The wiring section provides a separate layout for models after 1996.

Final Drive Oil and Backlash Preview

The PC800 lubrication table lists 150 cc of final drive gear oil after draining and 180 cc after disassembly. The two capacities distinguish a routine oil change from filling the final drive after teardown.

During ring gear spacer selection, the final drive chapter gives a service limit of 0.10 mm for the difference across three ring gear backlash readings.
