Sisu Citius Series 44, 49, 66, 74 and 84 Engines Workshop Manual

Sisu Citius Series 44, 49, 66, 74 and 84 Engines Workshop Manual PDF free online

This Workshop Manual is intended to assist with workshop operations and repair work.

Citius series engines (types 44, 49, 66, 74 and 84) are generally of the same construction, so the same repair instructions will usually apply to various engine types. The differences between the various engine types, which affect repair work, are mentioned in the technical data and repair instructions. All measurements are in millimetres and valid when the temperature of the parts is +20°C, unless otherwise stated.

Before starting any repair work, please read the safety instructions at the beginning of this book. Make sure that you have all the necessary tools, parts and accessories to hand. The special tools mentioned in the work instructions are not all essential, but they speed up and facilitate the work and contribute to successful execution of the work. An engine which has undergone repairs must be run in just like a new one.

Should the engine require work not described in this manual, please consult your local agent or the Service Department of Sisu Diesel Inc., Linnavuori, Finland. To facilitate consulting, find out the following facts about the engine before contacting us:

  • engine type
  • engine number
  • model or equipment
  • hours operated or kilometres driven.

This Workshop Manual does not cover the regular service procedure as this is explained in the Citius series Instruction Manual.

As Sisu Diesel Inc. is continuously developing the products, all rights are reserved to alter the specifications, accessories and the service and repair procedure without separate notice.
