• For engines with marine transmission, Scania recommends a 6-point suspension or common rear suspension for pipes, transmission and engine. • Both the engine suspension and the engine bed should be designed so that there are no resonant oscillations within the engine speed range.
Built-on reverse gear can either have separate brackets or suspension attachments which are integrated with the engine. Contact Scania or the supplier of the reverse gear about approved type of suspension for reverse gear. Example of suspension of a reverse gear 02:01 Issue 6.0 en-GB...
For the installation to be approved in a propeller installation with a reverse gear ratio greater than 2:1, the pressure forces must be fully taken up in the reverse gear sus- pension. Contact Scania if it is difficult to determine the size and type of load. Lifting the engine WARNING!
It is important that the industrial clutch is not subjected to loads that could cause overloading of the clutch bearings. For heavier operation, e.g. belt transmissions where large lateral forces arise, Scania recommends using clutches which absorb lateral forces in the main bearings. This type of clutch does not have a support bearing in the flywheel.

Torque take-off and transmissible power from the front end of the crankshaft Max. torque take-off is 1,200 Nm for DI13 and 800 Nm for DI09 and DI16. Trans- missible power at different engine speeds is shown in the table below.
If these power take-offs are not loaded, they must be removed. Otherwise, parts from the bearing housing may get into the engine and cause a breakdown. Scania also recommends that SAE B power take-offs facing forwards are removed if they are not to be loaded.

600 Nm. Note: The maximum permissible bending torque for all side-mounted power take-offs with SAE B connection on all engine types is 30 Nm. Overview of power take-off for DI09 and DI13 Power take-offs Direction Connection Rotation Max.
Data for torsional oscillation calculation Form for torsional oscillation calculation is available on SAIL. Contact your nearest Scania distributor if you require help downloading the form or with the torsional oscillation calculation. The following information is required for the calculation: Engine type designation and classification society.
INSTALLATION MANUAL Torsional oscillations The equipment fitted to the front and rear parts of the engine. State Scania part number. Gear ratios. Moment of inertia (j) or rotating mass (GD2) for component couplings, flanges, gears, shafts, propellers, generators and similar which rotate with the engine.

ISO 3046/V applies where appropriate. The torsional oscillation calculation does not allow Scania to provide any statement or guarantee as regards hunting. Torsional oscillation calculations may also be performed by companies other than Scania.
