INTRODUCTION
The PS990 Hydraulic Ram Piston will fit all Sealey hydraulic puller sets
and is also suitable for use with other popular makes of hydraulic gear
pullers. Screw mechanism converts power to 10 Ton ram head with
enough force to remove most stubborn bearings, pulleys and shafts.

4. INSTRUCTIONS FOR USE
4.2
Check that the specification of the puller tool you will be using is
compatible with the ram unit.
4.1.
Confirm that the workpiece is retained by interference fit (parallel
or taper) only.
4.2.
Assemble the ram into the chosen puller, (see typical pullers as
shown in fig.1), and adjust
T-handle (Fig. 2.A) so that tommy
bar (fig.2.B) is approximately
80mm (3) above top of ram, see
fig.2.
4.3.
Fit the puller to an appropriate
position behind workpiece and then
screw the ram
body
down until it
makes contact with the end of the shaft from which the workpiece is
to be pulled. (If the shaft has a centre position machined into its
end surface use a matching centre adaptor to locate centrally with the
shaft.
4.4.
Turn T-handle clockwise, by hand only, to pull workpiece from shaft.
4.5.
Do not screw T-handle in further than 25mm (1) from end of the
ram (see fig.2). If workpiece requires additional movement
then unscrew T-handle to 80mm from end of ram, screw ram
body down so that centre adaptor again contacts shaft and
then continue to draw workpiece up shaft.
IMPORTANT:
The maximum safe load for the puller can be achieved by
hand effort alone.
The use of tools or levers on the tommy bar to
increase the load will damage the puller and may result in injury.
Such misuse will also invalidate the warranty.
If the workpiece does not move, with maximum puller force applied,
DO
NOT
hit it, or the puller, in an attempt to jar it free. Damage to
puller/workpiece and personal injury may result. Use a larger capacity
puller.
