Page 3: Engine Suspension
If the angles of inclination are exceeded, lubrication system performance will deteri- orate, which can cause damage to the engine or reduce its service life. There are two standard engine suspension designs: • flexible engine suspension • rigid engine suspension. 01:01 Issue 8.0 en-GB © Scania CV AB 2016, Sweden... -

Page 5: Rigid Engine Suspension
It is also possible to construct flexible engine suspension between the frame and the engine bed to reduce the transmission of vibration to the engine bed. 01:01 Issue 8.0 en-GB © Scania CV AB 2016, Sweden... -

Page 12: Engine Alignment
Relatively large deviations are permissible with flexible couplings. However, align- ment should be as accurate as possible to achieve low vibration and a long service life on the coupling. 01:01 Issue 8.0 en-GB © Scania CV AB 2016, Sweden... -

- Page 15 Angular deviation between the shaft centrelines can also be checked using a 0.1 mm feeler gauge. Do this by measuring the distance between the surfaces of the flanges at the outer edges. During measurement, the engine must be tightened onto the engine bed. 01:01 Issue 8.0 en-GB © Scania CV AB 2016, Sweden...

Page 18: Power Transmission
Many engine installations require a flexible coupling between the engine and the driven unit to dampen irregularities in the system. Information about suitable flexible couplings can be obtained from your nearest Scania distributor or from the coupling supplier. Carry out a torsional oscillation calculation before selecting a flexible coupling. - Page 19 For heavier operation where large lateral forces arise, such as belt transmissions, 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.

Page 20: Transmission Types
A different belt tension results in in- creased bearing load and displacement of the centre of the load. The lateral loading can be reduced by e.g. changing the size of the pulley. 01:01 Issue 8.0 en-GB © Scania CV AB 2016, Sweden... - Page 21 Always use paired belts or V-belts in multi-belt installations.

Page 22: Power Take-Offs
Power take-offs The engines can be supplied with different types of power take-offs for driving units. Note: Only components from Scania are permitted in the belt transmission. Front-mounted power take-offs Example of shaft journal for direct connection of flexible coupling. - Page 23 In order to avoid impermissible radial forces at the front end of the crankshaft when there are many belts in the transmission, the driven units should be positioned so that the forces balance each other out. 01:01 Issue 8.0 en-GB © Scania CV AB 2016, Sweden...

Page 25: Side-Mounted Power Take-Offs
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. - Page 26 600 Nm. Note: The maximum permissible bending torque for all side-mounted power take-offs with SAE B connection is 30 Nm. This applies to all engine types.

Page 32: Torsional Oscillations
If no torsional oscillation calculation has been carried out, or one has been carried out with unsatisfactory results, Scania Engines takes no financial or technical responsi- bility for installation problems or engine breakdowns caused by torsional oscilla- tions. -
Page 33: Data For Torsional Oscillation Calculation
The following information is required for the calculation: Engine type designation and classification society. Operating speed and power. 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 etc. -

M14, 8.8 149 Nm Sticker “Powered by Scania” Customers who so desire can order the sticker “Powered by Scania” to attach to the machine. P O W E R E D Machines operated using Scania's industrial and marine engines must be uniformly marked, therefore this is the only sticker which should be attached to the machine containing the engine.
