Section 1 - Cylinder Block - Group 01 Cylinder Block - General Information M11 Page 1-7 Cylinder Block - General Information These procedures apply to M11 engines. The differences between engine models, due to the application and the optional equipment, is included in the instructions. Omit the steps that do not apply to the engine being rebuilt. 1. A Warning statement is included for any component or assembly that weighs more than 23 kg [50 lb]. To avoid personal injury, use a hoist or get assistance from more than one person when removing or installing these parts. 2. Most of the capscrews used on the M11 engine are metric.
All fasteners have right-hand threads unless a states that a fastener has left-hand threads. Discard all gaskets, seals and o-rings unless they are needed for a failure analysis. Label, tag, or mark the parts for location as they are removed. This will help in finding all of the parts that can be involved in a failure, and simplify the assembly procedure. Some parts can also be used again. Force must be used to remove certain parts. A mallet can be used when force is required. All of the fasteners must be removed before using force. Avoid as much dirt as possible during disassembly. The accumulation of dirt will make it more difficult to clean the components.
Torque values are listed in each assembly step. If a torque value is not specified, use the chart listed in the specifications section, Group 18, to determine the correct torque value. Many of the gaskets and o-rings are manufactured from a material designed to absorb oil. These gaskets will enlarge and provide a tight seal after coming in contact with oil. Use only a recommended contact adhesive or a vegetable based oil to install these parts. Always use a capscrew of the same system, metric or U.S.Customary, the same dimension and the same grade as the capscrew removed. The use of a longer capscrew than the capscrew that is listed can result in damage to the engine.
Cylinder Block (1-01) Disassembly Cup Plugs - Removal Use the following procedure to remove all cup plugs from the cylinder block. Use a center punch to mark the cup plugs for drilling. Drill a 3mm [1/8 inch] hole in the cup plugs. Use a dent puller to remove the cup plugs. Discard all used cup plugs.
