5.3 Tensioner Operational Checks
The following checks and inspections should be performed
before placing the tensioner into service, with the hydraulic hose
and electrical cables disconnected.
• Visually inspect the tensioner for any signs of damage or
excessive amounts of oil (which could indicate a potential
leak).
• Operational Check #1: Hold the tensioner upside down and
ensure that the puller sleeves freely retract by approximately
20 mm [0.78 in]. See Figure 4.

• Operational Check #2: With the tensioner still in the upside
down position, depress the nut rotating sockets by hand
by approximately 5-10 mm [0.20 - 0.39 in.] to ensure they
move freely and are returned to their original position by the
compression springs. See Figure 5.

• Operational Check #3: Use a 3/8 inch drive extension to
rotate the drive gears on the gearbox at least one complete
revolution in both directions. Check that they rotate freely
without binding, and that they rotate the nut rotating sockets.
See Figure 6.

an Enerpac Authorized Service Center before being placed into
service.
