Get home power

Those of you who are driving the main shaft using a hydraulic motor:
What are the down sides to pushing the main shaft with the
transmission in neutral?  Can this be done indefinitely without
damage?  Is there a ball park cost figure for adding one of these
clamp-on drive units?

We have a Twin Disc transmission that will run for several days in neutral
without a problem.  That said, we have installed a trailing pump that
circulates the transmission oil while the get home drive is engaged.  This
allows continuous operation.

The complete drive installation was in excess of $30,000.00+ because we had an
early model from a previous manufacturer that subsequently sold the rights to
Wesmar.  We had to do a lot of extra machining and hydraulic work to make the
drive engagement operational from a remote location and we also machined new
NiAl Bronze engagement cog rings to replace the Aluminum cogs that came with
the unit.  I am not sure, but I think you can install the new improved drive
from Wesmar for $20,000 or less depending on the size of the unit.  Les Dobbe
stated that Keypower has eliminated the need for cutting the main shaft (the
main reason we did not go with Keypower) and that makes the Keypower unit a
good option too in my opinion.  I am not completely sure, but I think both the
Keypower and Wesmar units are priced similarly.
