Servicing the Tool

Lubricate the spigot on the *Front Gland Guide Rod tool and then place the Front Seal Gland 15, Rod Seal 25
end first, fully over spigot. Insert *Front Gland Guide Rod into the rear of the Body 2 and then push the Front
Seal Gland fully into the bore within the Body. Reasonable force is required to insert Front Seal Gland into the
Body, so the use of a press or vice may be necessary. Remove the *Front Gland Guide Rod while ensuring that
the Front Seal Gland stays in place.

Lubricate the seal groove and major external diameter of the Piston 1 with Molykote
inner o-ring from Piston Seal 26 over the front of the major Piston diameter and into the seal groove.

Screw the *Piston Bullet – Front on to the Piston 1. Place the *Piston Seal Sleeve over the Piston shaft and
then place the outer sealing ring from Piston Seal 26 over the *Piston Seal Sleeve so that it rests on the tapered
diameter. Lubricate the surface of the *Piston Seal Sleeve with Molykote

Place the *Piston Seal Plunger over the Piston 1 shaft and the *Piston Seal Sleeve so that the open end of the
*Piston Seal Plunger rests on the outer sealing ring of Piston Seal 26. Using the *Piston Seal Plunger, push the
outer sealing ring over the *Piston Seal Sleeve and into the Piston seal groove. Reasonable force is required to
expand and insert the outer sealing ring on the Piston, so the use of a press or vice is necessary.
 Remove the *Piston Seal Plunger and the *Piston Seal Sleeve from the Piston 1. Lubricate the *Piston Bullet -
Front, Piston shaft and Piston Seal 26 with Molykote

Screw the *Piston Guide Sleeve fully into the rear of the Body 2. Lubricate the bores in both the Body and the
*Piston Guide Sleeve with Molykote

Connect the spare *Quick Coupler - Female to the Quick Coupler - Male 10 on the Hydraulic Hose – Pull 19.
This will allow air to be released from the pull side Piston 1 when inserting the Piston.
 Insert the assembled Piston 1 into the rear of the Body 2 and through the assembled Front Seal Gland 15. Push
the Piston into the fully forward position until it stops against the Front Seal Gland. Hydraulic oil will be
expelled from the Hydraulic Hose – Pull 19. Reasonable force is required to insert the Piston into the Body, so
the use of a press or vice may be necessary.

Remove the spare *Quick Coupler - Female from the Quick Coupler - Male 10 on the Hydraulic Hose 19.
Remove the *Piston Guide Sleeve from the rear of the Body 2.

Slide O-Rring 30 over the End Cap 17 and into the external groove. Insert the Spiral Back-up Ring 36 in the
same groove, behind the installed O-Ring. Refer to the General Assembly and Parts List for the correct
orientation of the O-Ring and Spiral Back-up Ring.

Clamp the tool handle in a vice with soft jaws so that the tool is pointing nose down.

Lubricate the surface and leading edge of the Body 2 bore into which the End Cap 17 is to be installed with
Molykote ® 111 grease.

Fill the rear of the Body 2 with Enerpac
the Body.
 Connect the spare *Quick Coupler - Male to the Quick Coupler - Female 11 on the Hydraulic Hose - Return 18.
This will allow air to be released from the return side of the Piston when inserting the End Cap 17.
All numbers in bold refer to the General Assembly and Parts List on pages 15, 16 and 17.
