Servicing the Tool
Assemble in reverse order to dismantling noting the following points:

Clean all components before assembling.

To aid assembly of seals apply a light coating of Molykote
and the assembly tools.

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 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

Clamp the tool body in a vice with soft jaws so that the tool is pointing nose up.

Fill the rear of the Body 2 with Enerpac

Apply a light coating of Molykote
Seal 26.

Place the Piston 1 in the front of the Body 2, so that the rear edge of Piston Seal 26 rests on the leading edge
of the main bore within the Body. When inserting the Piston the take care not to damage the Piston Seal on the
threads at the front end of the Body.

Place the *Piston Extraction Sleeve inside the bore of the *Piston Extraction Rod and then screw the assembly
into the centre of the *Piston Extractor. Place the assembled *Piston Extractor Tool over the shaft of Piston 1
and screw the *Piston Extractor fully into the font of the Body 2. Refer to the illustration below for the correct
assembly of the *Piston Extraction Tools.
