Lengths allowed
1. The maximum work lengths which can be produced, both for the middle and sliding sections “LG” or “LZ” (see Figure 16),
can be determined in relation to the external diameter of the existing vehicle pipe and the maximum running rpm (see for-
mula and Table 2.13).
If the shaft length calculated in this fashion is insufficient for the modification at hand, it is necessary to insert a new section
with the same characteristics as those mounted.
2. In some cases, a drive shaft with a larger diameter can be used and calculated (again, see Table 2.13) in relation to the length
required and the maximum number of engine rpm.

LG Length of intermediate sections
LZ Length of sliding sections
LT Total length
For sliding shafts, the length LG must be evaluated between the universal joint centres and with the sliding stem in the intermediate
position. Always check both stems LG and LZ.
The maximum number of engine rpm must be calculated with the following formula:
