large mounts are used on the back of the engine.
•
Ensure that the engine has been installed for at least 24 hours before shaft
alignment is checked, to allow the mounts time to settle under the engine weight.
•
Ensure that the anti-vibration mount centre screw is sufficiently raised so as not to
touch the engine bed. If this occurs, excessive engine vibration will be experienced
through the hull.
•
For best results, fit the front AV mounts into the front holes in the engine rails. If the
engine room space is a problem the mounts can be fitted slightly further back in the
alternative holes and the front of the rail cut off – leaving 50mm of material to retain
strength (measuring from the centre of the mount hole to the front end of the rail).
Note: This procedure is only possible on non VDO Travel Power engines, and may
result in a very slight increase in vibration. AV mount installation points are shown
on (
