Q
:
The tensioner is at its final pressure, but the nut cannot be loosen.
A
:
If the nuts cannot be loosened at the final pressure, continually increasing the pressure
will not help and can be dangerous and in some cases make it harder to remove the nut.
Check the nut to see if its set screws have been loosened. Check for and remove any
corrosion around the nut's threads.
Q
:
How do I clean the conical threads on a stud?
A
:
The conical threads are best cleaned using a spiral wound brass brush in a drill as
described in section 5.2.1
Q
:
During the initial steps of removing a tensioned stud, the stick‐out length is found to be
wrong.
A
:
Do not proceed. Contact Riverhawk for assistance. With the wrong stick‐out length, the
hydraulic tensioner has a limited stroke and may not work properly and can be
damaged.
Q
:
The hydraulic pump appears to be leaking.
A
:
Check the hose connection to the hydraulic pump. If the 1/4" high pressure fitting is not
assembled correctly it may look like the pump is leaking. If the problem continues, it
may be necessary to open the pump kit. Contact Riverhawk for guidance.
Q
:
The hydraulic hose has a collar on it that can't be moved by hand
A
:
The collar is sometimes held in place with a thread locking compound. This prevents the
collar from moving too easily. It may be necessary to adjust this collar with a set of vise‐
grip pliers. Be careful to not strip the threads off the tube or hose end.
