# Tensioner Installation

- Prior to installing the tensioners see also Pre-procedure Checks to determine the suitable tensioner arrangement to be used.

- Prior to installing the tensioners ensure the bolt threads are clean and free of damage.

1. Fit the nut socket over the hexagon nut.

2. Fit the tensioner over the stud until it sits flat on the bolted joint. Ensure the bridge access window faces radially out with easy accessibility to the tommy holes in the nut socket. Ensure the hydraulic connections are also facing radially outwards.

3. Place the thread insert into the tensioner bore until contact is made with the top face of the bolt. Using the tommy bar rotate the thread insert downwards until the thread insert head makes contact with the top face of the tensioner piston.

4. Ensure the pump pressure release valve is fully open and the pump is off. Connect the link hoses to the installed tensioners. See also configuration instructions for different tensioning procedure configurations and illustrations.
