5.7 DISMANTLING INSTRUCTIONS
IMPORTANT – ENSURE THE MAINS POWER SUPPLY TO THE HYDRAULIC PUMP UNIT IS SWITCHED OFF BEFORE
REMOVING THE NOSE ASSEMBLY OR DISMANTLING THE PLACING TOOL.
Before Dismantling:
• Uncouple the Quick Couplers 10 and 11 and the electrical Control Cable 14 between the placing tool and the Hydraulic
Hose Assembly.
• Remove the nose assembly from the placing tool as per the instructions in the relevant nose assembly datasheet.
• The potentially dangerous substances that could have deposited on the machine as a result of work processes must be
removed before maintenance.
For a complete service of the tool, we advise that you proceed with dismantling the tool in the order shown on pages 13 to
16. After dismantling the tool we recommend that you replace all seals.
Head Piston Assembly:
• Using a small flat screwdriver, remove the Pin 41 from the Collet Adapter 40.
• Unscrew and remove the Collet Adapter 40 from the Piston 1.
• Clamp the tool body in a vice with soft jaws so that the tool is pointing nose up.
• Using a 2.5mm Allen Key, unscrew and remove Set Screw 28.
• Connect the spare *Quick Coupler - Female to the Quick Coupler – Male 10 on the Hydraulic Hose - Pull 19. This will
release pressure from the pull side of the Piston and ease the removal of the Seal Gland 17.
• Insert the *Seal Gland Removal Tool into the front of the Nose Cap 15 and attach to the Seal Gland 17 using the three
*M5 x 35 Skt Cap Head Screws.
• Using a large adjustable spanner or clamp, fully unscrew Nose Cap 15, from the Body 2. In doing so the Seal Gland 17 will
be drawn out of the Body. Reasonable force will be required. Once the Nose Cap is unscrewed the complete assembly
can be pulled off of the Piston 1 and removed from the Body.
• Unscrew the three *M5 x 35 Skt Cap Head Screws and remove the *Seal Gland Removal Tool from the Nose Cap 15 and
Seal Gland 17. The two parts can now be separated.
• Using a small flat screwdriver, remove O-Rings 21 and 33 from the Nose Cap 15 and discard.
• Using a small flat screwdriver or similar tool, remove O-Ring 23 and Anti-Extrusion Ring 27, from the external groove on
the Seal Gland 17, and discard. When removing the seals, take care not to damage the surface of the Seal Gland with the
screwdriver.
• Remove Rod Seal 25 and Wiper Seal 22, from the internal grooves on the Seal Gland 17, and discard. When removing the
seals, take care not to damage the surface of the Front Seal Gland with the screwdriver.
• Remove Front Bearing Ring 24 and check the part for wear or damage. Discard if necessary.
• Remove the placing tool from the vice and empty the hydraulic oil from the front of the tool and then re-clamp the tool
in the vice as before. Remove the spare *Quick Coupler – Female from the Quick Coupler - Male 10.
• Connect the spare *Quick Coupler - Male to the Quick Coupler - Female 11 on the Hydraulic Hose – Return 18. This will
release any pressure from the return side of the Piston 1 and ease the removal of the Piston.
• 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 complete *Piston Extractor Tool assembly over the shaft of Piston 1 and screw the *Piston Extractor fully into
the font of the Body 2. Screw the *Piston Extraction Rod into the *Piston Extractor until it stops against the front face of
