4.3.2 Alignment method with tailstock shafts
1. Engine.
2. Reverse transmission.
3. Variable-length universal joint.
- Selected according to the instructions of the manufacturer.
- In compliance with the installation instructions.
4. Propeller axle.
To facilitate the correct alignment of the engine and reverse transmission, that is to obtain identical connection an-
gles ß1 and ß2:
- install two alignment shafts 6 in place of the universal joint;
- the shafts must have the same length;
- align the two units so that the ends of the shafts meet, to ensure that angles ß1 and ß2 are identical;
- at the end, remove the alignment shafts and install the universal joint;
- make sure that the longitudinal axes of the flexible coupling, alignment shafts and reverse transmission input shaft
are aligned on the same vertical plane.
Make sure that the transmission was installed by leaving enough space for performing proper maintenance to replace
the filter, oil and pump, and for accessing the oil level rod.
Verify that the oil drain plug is easily accessible.
Defective alignment can cause irreversible damage to the transmission, noise, vibrations, and damage to the
hull's sealing systems.
ZF Padova S.r.l. is not required to perform warranty repairs in case of ruptures.
