Check Driveline Maximum Length
Refer to Figure 1-7:
Make sure driveline collapsible length is acceptable. If
needed, refer to “Check Driveline Collapsible Length”
on page 12.
The driveline maximum allowable length must, when fully
extended, have a minimum overlap of the profile tubes by
not less than 1/3 the free length with both inner and outer
profile tubes being of equal length.
1.
If not already completed, apply multi-purpose grease
to inside of outer profile and reassemble driveline.
2.
Assemble the two driveline profiles together with just
1/3 overlapping of the profile tubes as shown below.
Once assembled, measure, and record the
maximum allowable length for future reference.
