44117A 8 Mercruiser PLATE ASSEMBLY, Transom

Introduction
The correct installation of emissions critical components is vital to comply with the relevant emissions legislation. In addition, the document highlights the key assembly characteristics of other components that are transported loose. The assembly of the loose components is carried out by a representative of the customer.This Special Instruction is to be used in addition to the Service Manual. This document should be used as an assembly guide or a reference document when developing processes for production assembly facilities. Critical assembly characteristics such as tightening torques, component orientation, and assembly sequences should be followed to achieve the required product quality and emissions regulations.The Service Manual consists of the following manuals.

SpecificationsCustomers are permitted to paint the engine as received or as part of a power train sub assembly. These engines are supplied in gray primer.The customer must not paint the exhaust systems, Electronic Control Module (ECM), starting motor, alternator, belts. The customer must not paint any filters and filter canisters. The canisters include fuel, air, oil.The customer must develop suitable plugs and masks to a standard equivalent to the engine assembly plant.The customer must prevent water ingress into the engine by maintaining a plugging standard equivalent to the engine assembly plant.Engine Air Cleaner for C3.6 and C2.8 Industrial Engines
Illustration 1 g03179402
Typical example
The engine air cleaner (1) can be supplied as a loose assembly. The engine air cleaner should be mounted horizontally. The dust exhaust port must be at the lowest point and positioned in a direction that is down.Note: Do not paint the dust exhaust port. Solvents and chemicals will shorten the usable life of the exhaust port.Note: There are several variations of engine air cleaner.Select the appropriate sized fasteners for the relevant air cleaner. Bolts should have a flanged head or be installed with a washer under the bolt head.Standard duty air cleanerTighten the M10 bolts to the following torque. ... 38.5 5.5 N m (28.4 4.1 lb ft)Heavy-duty air cleanerTighten the M8 bolts to the following torque. ... 15 3 N m (133 27 lb in)
Illustration 2 g03415816
Typical example
The position of the clamp (2) in relation to pipe or component bead (3) is crucial. Ensure that clamp (2) is installed on the correct side of the pipe or component beads (3).Air Temperature Sensor for C3.6 and C2.8 Industrial Engines
The air temperature sensor can be supplied loose.
Illustration 3 g03178776
Typical example
Install the sensor (1). Tighten the sensor to a torque of 20 3 N m (177 27 lb in).Note: Ensure that the O-ring is correctly installed to the sensor. Do not lubricate the O-ring seal.Electronic Control Module (ECM) and Link Wiring Harness Installation on C3.6 and C2.8 Industrial Engines
The Electronic Control Module (ECM) is supplied in a transit position on the engine.The customer must ensure that the correct ECM is matched to the correct engine. Ensure that the engine number on the ECM label is the same as the engine number on the engine emissions label.Note: The Electronic Control Module (ECM) is mounted to the application. The ECM must be mounted with four M6 bolts.Tighten the M6 fasteners to the following torque ... 10.5 N m (93 lb in)Harness strain relief components must be positioned within 200 mm (8 inch) of each ECM connector.The strain relief component must be mounted to the same surface as the ECM. The purpose of each strain relief is to prevent excessive movement between the connector, harness, and engine ECM.Harness strain relief is required for both engine interface connectors.The harness should be supported with brackets to prevent the mass of the harness straining the connectors.Note: Care must be taken to avoid damage to the connector pins during installation of the harness.Fuel Filter with Electrical Priming Pump and Secondary Fuel Filter on C3.6 and C2.8 Industrial Engines
The fuel filter has two fuel connections.
It is important to maintain extreme cleanliness when working on the fuel system, since even tiny particles can cause engine or fuel system problems.
Illustration 4 g06377807
Typical example
The secondary fuel filter has two fuel connections.
Illustration 5 g06377812
Typical example
It is recommended the fuel filter with electronic priming pump must be mounted with three M8 fasteners and the secondary filter must be mounted with two M10 fasteners. Tighten the three M8 fasteners to torque of 22 N m (195 lb in) and the two M10 fasteners to the torque of 44 N m (32 lb ft).Installation of Tube Assemblies for the Low-Pressure Fuel System on C3.6 and C2.8 Industrial Engines
Ensure that the fuel return to tank tube assembly is not blocked or restricted in any way. Ensure that the tube assemblies for the low-pressure fuel system are correctly installed.Failure to heed this warning can lead to premature failures, product damage, and may, in conjunction with other factors or circumstances, result in a risk of personal injury or death.
Note: The inlet and return tube assemblies for the low-pressure fuel system are supplied by th
