• Using a small flat screwdriver remove O-Ring 23 and Spiral Back-up Ring 34, from the external groove on the Front Seal
Gland 15, and discard. When removing the seals, take care not to damage the surface of the Front Seal Gland with the
screwdriver.
• Remove Rod Seal 25 and Wiper Seal 22, from the internal grooves on the Front Seal Gland 15, and discard. When
removing the seals, take care not to damage the surface of the Front Seal Gland with the screwdriver.
• Remove the Front Bearing Ring 24 and check the part for wear or damage. Discard if necessary.
• Using a small flat screwdriver, remove O-Ring 21 from the Body 2 and discard.
• Remove the spare *Quick Coupler - Female from the Quick Coupler - Male 10 on the Hydraulic Hose - Pull 19.
• Do not remove Set Screw 42 from the Body 2.
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® 111 grease to all seals, seal grooves, back-up rings and the
assembly tools.
• Slide O-Ring 23 over the Front Seal Gland 15 and into the external groove. Insert the Spiral Back-up Ring 34 in the same
groove, in front of 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.
• Press the Front Bearing Ring 24 into the internal recess within the Front Seal Gland 15 and then install Rod Seal 25
behind the Front Bearing Ring. Install the Wiper Seal 22 in the front recess of the Front Seal Gland. Refer to the General
Assembly to ensure the correct orientation of the Rod Seal and Wiper Seal.
• Lubricate the surface and leading edge of the Body 2 bore into which the Front Seal Gland 15 is to be installed with
Molykote® 111 grease.
• 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® 111 grease. Slide the 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® 111 grease.
• 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® 111 grease.
• 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® 111 grease.
• 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 of the 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 - Pull 19. Remove the
*Piston Guide Sleeve from the rear of the Body 2.
• Slide O-Ring 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.
• Press the Rear Bearing Ring 29 into the internal recess within the Rear Seal Gland 16 and then install Rod Seal 28 behind
the Rear Bearing Ring. Install the Wiper Seal 31 in the rear recess of the Rear Seal Gland. Refer to the General Assembly to
ensure the correct orientation of the Rod Seal and Wiper Seal.
All numbers in bold refer to the General Assembly and Parts List on pages 16, 17 and 18.
