41161-ZY3-B00 Honda SHAFT, PROPELLER (COUNTER ROTATION)

2. Terms And Units
The following terms and units are used throughout the entire texts of this manual.(1) Front and rear The terms "front" is the fan side and "rear" the flywheel side of the engine.(2) Right and left The terms "right" and "left" shall be used to indicate the side as viewed from the flywheel side of the engine.(3) Service standard terms * Nominal value Shows the nominal dimensions, dimension of an individual part, standard clearance between parts in an assembly, or the standard performance of an assembly.* Limit Shows the value of a part at which the part is no longer serviceable from the performance as well as strength viewpoints, requiring replacement or repair.(4) Tightening torque Over- or undertightening of bolts and nuts has critical effects on performance and functions. Tightening torque is therefore specified for some tightening points.All tightening torque specifications may be considered as "dry" unless "wet" is specified. Where no tightening torque is specified, use a torque value specified in the General Bolts and Nuts Tightening Torque Table.(5) Units For length, weight, area, and volume, the SI unit (International System of Units) is used with the metric notation jointly shown in parentheses. Temperature is shown in centigrade (°C).3. Table Of Conversion Rate For Foot-Pound Units Into SI Units

2. Major Specifications
2.1 Major Specifications
2.2 Engine Outputs Classified By Application
1. The output (SAE, gross) is corrected to standard ambient conditions based on SAE J1349.2. The continuous rated output allows 10% (one hour) overload operation.3. Engine Number, Name Plate And Caution Plate
(1) Engine number The engine number is stamped on the rear left of the crankcase as illustrated. The engine number is important in knowing the history of the engine.(2) Name plate, caution plate The name plate and caution plate are attached to the portion shown in the illustration, and indicate the following items.(a) Name plate 1. Engine model2. Total displacement3. Maximum output4. Valve clearance5. Firing order6. Fuel injection timing(b) Caution plate 1. Valve clearance2. Firing order3. Fuel injection timing4. General Precautions For Servicing
Before starting the service procedures, check for total operating hours and use conditions of the machine as well as user's complaints and requests to know exactly the engine conditions. Record information where necessary.To ensure you are doing correct and efficient service jobs, observe the following precautions: 1) Before performing the service procedures given in this manual, know the trouble spots and isolate the possible cause to determine whether the removal or disassembly procedure is required.2) Select a flat surface for the service job.3) When servicing the electrical system, be sure to disconnect the (negative) cable from the battery.4) Carefully check parts for oil leaks before cleaning. After cleaning, it may become difficult to spot defective areas.5) Ready and make the most of the special tools required for servicing. Use the right tools (specified special tools) in the right place to prevent damages to parts and personal injury.6) Make alignment marks and keep disassembled parts neatly arranged to ensure that they are reassembled into the right positions.* Special care must be taken for assemblies involving a number of parts, similar parts, or parts identical at right- and left-hand sides to ensure correct reassembly.* For alignment and punching markings, select a position that would not mar the appearance and function.* Clearly distinguish parts to be replaced from those reused. 7) The oil seals, packings, O-rings, and other rubber parts, gaskets, and split pins must be replaced with a new one whenever they are removed. For replacement, use Mitsubishi Genuine parts. 8) Apply the specified grease to U-packings, oil seals, dust seals, and bearings before installation.9) When work requires an assistant or two, always make sure of the safety each other. Never play with switches and levers.10) Make sure that your shoes are free from grease and oil especially when working on a heavy item.11) When checking or changing lubricants, wipe off grease and oil from parts immediately with a cloth.12) Special care must be taken in handling sensors and relays which are susceptible to shocks and heat.13) Use care so that hands and fingers are not injured by sharp edges or corners of the parts.14) Wear safety goggles whenever handling a grinder or welding machine. Wear gloves as required to ensure utmost safety.5. General Bolts And Nuts Tightening Torque Table
Unless otherwise specified, the parts and equipment of vehicle must be tightened by the following standard bolts and nuts. Tightening torques for these bolts and nuts are shown below. 1. Threads and seat surfaces must be in dry state.2. When there is a difference between the nut and bolt (stud) identification marks, tighten to the torque corresponding to the bolt (stud) identification mark.Standard bolts and nuts Flange bolts and nuts
