Drive Component Assembly
Before assembly, apply a liberal coat of Revol R5 Moly
Anti Seize to the following areas:
Inside surfaces of both sideplates including the •
shuttle bore.
Shuttle component (all surfaces except threaded •
hole).
Slider component (all surfaces).•
The pocket where the drive shoe is located within •
the crank (not the crank bore).
The driving head of the crank that assembles •
into the slider.
Body sideplate journals.•
Square drive bearing journals.•
Square drive cap bearing journals.•
Threads of endcap.•
IMPORTANT: Do not apply lubricant to the ratchet
and drive shoe teeth.
The hydraulic torque wrench drive components must
be lubricated using the specied product only. Using
alternative lubricants will affect the output and possibly
lead to premature component failures.
Assemble the slider to the shuttle and verify it slides 1.
freely (check that the slider is not installed upside-
down). Install the shuttle/slider assembly into the
wrench body.
