Installing a Supplementary Axle
As far as sliding shafts are co ncerned, length”LG” is measured between the universal joint centres, with the sliding stub in t h e
intermediate position. Always check both sections LG and LZ.
The maximum working revs c an be obtained u sing t he formula below:

Example of calculation of the maximum obtainable transmission length
Let us consider a 35C13 equipped with a ZF S5-200 gearbox. Let us assume you wish to use a propeller shaft LZ
with an outer diameter of 76.2 mm.
From the data below:
1. n
max
= 3600 rpm
2. i
G
=0.8
the following will be obtained:
n
G
= 3600 / (0.8) = 4500 rpm
This value c o rresponds to a maximum obtainable length of 1.400 mm.
The universal joints on the same shaft should not be rotated.
