MAINTENANCE
The torsional damper coupling
will withstand normal exposure to
hydraulic oil, diesel fuel, anti-freeze
solutions, and muriatic acid. The
coupling should be washed with a
mild soap solution and rinsed with
water after contact with the above
items. The coupling can be power
washed without damage as long as it is
installed in the vehicle. If the coupling
is power washed when not connected
to a cardan shaft, debris may be forced
internally at the bolt flanges damaging
the coupling.
