a. Clean the coupler thread and adaptor,
removing all traces of debris.
b. Coat the end of the adaptor which is to be
screwed into the coupler (i.e. the end with
the spigot and the female hexagon), with
‘Loctite 270’ and screw into the coupler
until it is finger tight.
c. Remove surplus ‘Loctite’.
d. Leave the assembly for a minimum of 30
minutes curing time before proceeding
with assembly into the HydraMax®
tensioner body.
Remove and discard the bonded seal.
Clean any dirt and debris from the tensioner
body counterbore and the coupler spigot face.
Insert a new bonded seal into the counterbore.
Lubricate the thread on the adaptor with
Omega 95 (or similar lubricant with a coefficient
of friction = 0.12), and tighten to a torque of
45 lbf.ft [61 Nm]. Ensure that the bonded seal
does not become nipped or dislodged during
tightening.
5b 1/8” BSP Fittings
On HM01 to HM03 tensioners the tools have
1/8” BSP ports. For these tools, a 1/4” BSP
(male) x 1/8” BSP (male) adaptor is used
between the coupler (1/4” BSP) and the
HydraMax® tensioner body (1/8” BSP). Both
ends of the adaptor are coned to create a metal
to metal seal with mating components. Should
the seal leak or become damaged then it should
be replaced as follows.
Unscrew the coupler and adaptor from the
tensioner body using the hexagon of the
adaptor (not the coupler).
Clean any dirt and debris from the tensioner
body counterbore and the sealing face on the
adaptor.
Do not lubricate the 1/8” BSP thread on the
adaptor it is important that the adaptor is
installed dry to prevent overloading the threads:
thread sealant should not be used.
Screw the adaptor into the tensioner body and
tighten to a torque of 22-26 lb.ft (30-35 Nm).
IMPORTANT: Care must be taken not to over
tighten the adaptors into the tensioner and to
use the hexagon on the adaptor to pull it in rather
than the hexagon on the male quick disconnect
coupler which could induce bending, leading to
failure.
9.0 STORAGE
Store tools fully retracted.
The finish will protect the tools from rust etc.
but for added protection a light coating of oil
or rust inhibitor should be applied to all plated
surfaces.
Cover the internal threads on the inside of the
puller bar and reaction nuts with a rust inhibitor.
Store tools upright.
Keep dust caps on the oil inlet nipples and
couplers.
Hydraulic Hose(s)
Wipe all hoses clean and apply a light coating
of oil or suitable rust inhibitor to all couplers and
tee blocks.
Always keep dust caps fitted to couplers.
Pump Unit
Always store the pump upright.
Apply a light oil coating or suitable rust inhibitor
to all exposed unplated metal items.
Leave the oil return to tank valve in the open
position.
Always keep dust caps on inlet and outlet
hydraulic fittings.
