Repair Instructions The work methods described in the Workshop Manual are applicable for a workshop environment. The drive has removed from the boat and is installed in an overhaul fixture. Unless otherwise stated reconditioning work which can be carried out with the drive in place follows the same working method. The warning symbols used in the Workshop Manual (see Safety Information for implication), WARNING! IMPORTANT! NOTE! By no means cover everything since the service work is conducted under a wide range of different conditions, and it is obviously impossible to foresee everything. All that can be done is to point out the risks that can occur from incorrect handling when working in a well-equipped workshop with work methods and tools approved by Volvo Penta. Where Volvo Penta special tools can be used for work procedures, these are described in the Workshop Manual. The object of special tools is to ensure the safest and most rational work method possible. If other tools or work methods are used than those recommended by Volvo Penta, then it is incumbent on the person using them to ensure that there is no risk of personal injury, damage, or malfunction. In some cases, there are special directions and user instructions for the tools and chemicals named in the Workshop Manual. These directions should always be followed even if there is no special mention of them in the Workshop Manual. Most risks can be prevented by means of taking elementary precautions and using common sense. A clean workplace and a clean drive will eliminate many risks of both personal injury and drive malfunction. Above all when working with bearing unions and sealing unions, it is extremely important to prevent dirt or foreign objects from getting in, since this can result in malfunction or reduce the life span of the repair.
Our joint responsibility Every engine consists of a large number of co-ordinated systems and components. The deviation of one component from the technical specification can dramatically increase the impact on the environment from what is otherwise a good engine. It is therefore extremely important to maintain the given tolerances, to implement the correct adjustments where applicable, and to use Volvo Penta Genuine Parts. The time schedule in the engine’s maintenance schedule must be followed. Certain systems, e.g. components in the fuel system, may require special competence and special testing equipment. For environmental reasons certain components are sealed at the factory and must not be worked on by unauthorised persons. Remember that most chemical products when incorrectly used can be damaging to the environment. Volvo Penta recommends the used of biologically decomposing degreasing agents for all cleaning of engine components, unless otherwise stated in the Workshop Manual. When working onboard boats special care must be observed to prevent oils and suds etc. unintentionally ending up the nature, e.g. via the bilge water.
Tightening torques Tightening torque for vital unions, which should be tightened with a torque multiplier, are indicated in the Workshop Manual, Technical data, Tightening torques and the manual’s work descriptions. All torque readings are applicable for clean threads, screw heads and mating surfaces. The torque readings refer to lightly oiled or dry thread. If lubricants, locking fluids or sealant are required for screw union, then the type is indicated in the work description. For unions where special torque denotations are not indicated, the general tightening torque is applicable according to the table below. The torque readings are guide values, and unions do not need to be tightened with a torque multiplier.
