Check Of Build-In Length - Vetus VDR 2 10 25 Instructions D'installation

• Fit the thrust bearing using the bolts supplied.
The self-locking nuts supplied cannot be used more than once.
If the thrust bearing has to be taken off again thereafter, then use nor-
mal bolts for the temporary fixing.
Tighten up the bolts until the rubber buffer has been compressed to 13 mm

Now tighten up the bolts in the clamping bush, in the order shown in
the illustration.
The bolts must be tightened in two steps up to the moment given in the table.

Check of build-in length

The build-in length must be checked after fitting the adapter flange and the
thrust bearing.
If the coupling is fitted well-aligned, the length L can easily be measured. If the
propeller shaft makes an angle with the engine then the length L can be deter-
mined by taking the average of the distance measured between the flanges at 4
points on the circumference.

If the length L differs from the length given in the table, this must be cor-
rected!
This can be done by adjusting the position of the thrust bearing or by moving
the engine lengthwise along the engine mounting.
