4.2 V-DRIVE reverse transmission
The above considerations apply. If the reverse transmission is mounted separately, a universal joint of variable length
is used. For the joint to work in optimal conditions (homokinetic transmission) and without damaging the reverse tran-
smission or the engine, it is necessary to follow a few simple installation rules, as shown in the following diagrams.
4.3 Alignment method
4.3.1 Alignment method with parallel-face flanges
1. Engine.
2. Flexible coupling.
3. Variable-length universal joint.
Selected according to the instructions of the manufacturer.
In compliance with the installation instructions.
4. Propeller axle.
5. Marine reverse transmission with input and output on the same face.
The engine and reverse transmission must be installed so that flanges A and B lie parallel to each other.
Make sure that the longitudinal axes of the flexible coupling, universal joint and reverse transmission input
shaft are aligned on the same vertical plane.
