DESCRIPTION
The Cherry® G84 pneumatic-hydraulic Lockbolt™ installation tool is
a heavy duty production tool designed for high speed, reliable
installation of the most popular sizes of aircraft Lockbolts™.
This powerful tool has been designed with many ergonomic
features: light weight (7.70 lb.), (3.5 kg), low recoil and noise, a
comfortable fit in the operator’s hand. The piston returns with a
force of 1200 Lbs., force necessary when used for Lockbolt™
swaging.
This tool can also be used to install blind bolts and rivets.
SAFETY WARNINGS
• Do not use beyond the design intent; do not use substitute components for repair.
• Use the tool with a pressure regulator; if one is not available, use the Cherry P-1505.
• Operating this tool with a damaged or missing stem deflector, or using the deflector as a handle, may result in
severe personal injury. Rotate the pin deflector facing away from the operator
• Wear proper PPE when operating, repairing, or overhauling this tool ( .)
• Any modification will void warranty and shall be at the customer's entire responsibility.
• Maintain the tool in a safe working condition at all times and examined at regular intervals for damage.
• Before disassembling the tool for repair, refer to the maintenance instructions. All repairs shall be undertaken
only by personnel trained in Cherry installation tools.
• Disconnect the air line from the tool inlet before servicing, adjusting, fitting or removing any accessory.
• Ensure that the vent holes do not become blocked or clogged and the hoses are in good condition.
• Wash thoroughly after handling the fluid; excessive contact could cause rashes.
• Operating air pressure not to exceed 110 psi (7.6 bar); use of a pre-set regulator (P1505) is recommended
• Do not operate the tool without the pulling head in place.
• All retaining rings, screwed end caps, air fittings, trigger valves and pulling heads should be attached securely
and examined at the end of each working shift.
• Do not pull rivet in the air or directed at any person.
• Do not pound on the rear of the tool head to force rivets into holes as this will damage the tool.
• Safety warnings must be explained all operators as part of training.

Tools with an integral Air Tools without an integral Air Pressure Regulator (P-1505),
Pressure Regulator (P-1505), MUST be connected to a dedicated, regulated airline.
may be attached to any shop airline.
Lockbolts: Place the lockbolt pin into the workpiece and place the collar over the pintail.
While holding the back end of the lockbolt in place, push the pulling head onto the serrated area of the stem.
• Caution: When using a non-self-releasing pulling head once the tool is placed onto the serrated end, it cannot be removed unless
going through the installation cycle which breaks the serrated end of the bolt.
The broken part (pintail) will eject through the rear of the riveter when using a straight pulling head and through the rear of the active
area of the tool for when using offset pulling heads.
If the tool does not release the swaged collar after installation, it can be adjusted by adding shims behind the pulling head collet. If
the tool still does not release, see troubleshooting instructions on page:
See pulling head installation instructions.
• Insert the blind fastener into the prepared hole and place the tool onto the serrated stem.
• Pull the trigger to activate the tool. Upon release of the trigger, the stem will eject to the rear of the riveter when using straight pulling
heads, and from the rear of the active area of the tool when using offset pulling head. Right angle pulling heads eject the stems
through the front..
PULLING HEADS
Pulling heads are not furnished and must be ordered separately. All Huck nose assemblies suitable for the 352 and 230 style tools will fit
directly on this tool.

FIRST AID
Skin: Wash thoroughly with soap and water as soon as possible. Casual contact requires no immediate
attention. If irritation develops, consult a physician.
Ingestion: Seek medical attention immediately. DO NOT INDUCE VOMITING.
Eyes: Flush with copious amounts of water. If irritation develops, consult a physician.
Inhalation: No significant adverse health effects are expected to occur on short term exposure.
Remove from contaminated area. Apply artificial respiration if needed. If unconscious, consult physician.
FIRE
Suitable extinguishing media: CO2, dry powder, foam or water fog. DO NOT use water jets.
ENVIRONMENT
Waste Disposal: In accordance with local, state and federal regulations.
Spillage: Prevent entry into drains, sewers and water courses. Soak up with diatomaceous earth or
other inert material.
Store the spent fluid in appropriate containers for disposal.
HANDLING
Eye protection required. Protective gloves recommended. Chemically resistant boots and apron
recommended. Use in well-ventilated area.
COMBUSTIBILITY
It is slightly combustible when heated above flash point. It will release flammable vapors which can
burn in open or be explosive in confined spaces if exposed to source of ignition.
STORAGE
Avoid storage near open flame or other sources of ignition.

OVERHAUL PROCEDURE
Caution:
• Maintenance and repair to be conducted only by trained personnel.
• Prior to attempting any repair or maintenance work, make sure the air is disconnected.
• Follow these instructions. Use special care handling sealing surfaces to avoid damage.
•
®
Replace all seals; before re-assembly, apply an O-ring lubricant (Parker silicone lube or equivalent) on all O-rings
• Apply a small amount of Loctite® 242 on the threaded components; curing time about 30 to 60 minutes.
• After tool overhaul, fill and bleed per instructions on page 6.
HEAD SUB-ASSEMBLY
Disassembly:
• Remove end cap (4). Thread tool 744-103 onto head piston (10) and push it out of the head cylinder (13).
• O-rings and back-up ring can be removed using a bent hook. Replace all seals.
• Remove the pressure relief valve sub-assembly (78); unscrew the ball seat (24) carefully from the spring seat (29) using soft jaws.
When all components have been removed, clean and dry thoroughly
Re-assembly:
• Reverse the above directions; before re-attaching, fill the handle with fluid to the top.

TM-G84 Rev.: H DCR# 15-0406 DATE: 5/5/15 Federal Identification Code: 11815 © 2015 Cherry Aerospace
HANDLE SUB-ASSEMBLY
Disassembly:
• Remove parts (65) through (69). Remove screws (76). Lift head assembly from the handle (33); empty and dispose of fluid
according to environmental regulations.
• Unthread the locknut (64) with a 1/2" socket wrench and then remove the air piston (63) by using wrench 700B65; hold the top
of the piston with tool 700A61 to prevent from turning. Push piston out when completely unthreaded
• Push the power piston (79) all the way up and remove packing plug (59) with the help of wrench 700B65.
• Tap the power cylinder (37) from the top; when loosened, it will fall through the bottom.
• Remove all the seals using a bent hook tool.
Assembly:
• The re-assembly sequence is the opposite of disassembly; to prevent damage to piston threads, the tightening torque for the
locknut (64) must be between 50 and 59 in.-lb. (5.65 and 6.67 N-m).
TROUBLESHOOTING GUIDE
PROBLEM POSSIBLE REASONS / SOLUTIONS
- Significant fluid loss: Bleed the system to purge the air out.
Short stroke or low pull force
If performance doesn’t improve, or excessive leakage continues, see below.
- Leaks around the seals or fittings indicate that they are not tightened to seal
properly: Tighten until no more leaks are observed.
Head Cylinder Fluid leakage
- Leaks at the front or back of head cylinder indicate worn/ damaged seals
Service head cylinder per instructions provided herein
- Broken or dislodged valve spring.
Air leakage at the spool valve - Worn or damaged valve spool seals: Disassemble and service air valve per Air
Sub-Assembly Overhaul Instructions.
- Piston or seal damage: Service head cylinder.
- Oil bypassing due to power piston displacement off its seat: Service Handle
Head piston is slow or seizes Subassembly per instructions provided below.
- Clogged air muffler or filter Clean thoroughly with solvent and back-blow with
compressed air.
- Pressure relief valve (78) malfunction: Remove, inspect and clean components
Head Piston (64) does not return fully forward thoroughly. Replace seals and damaged components.
even after system bleeding - Return Cylinder Spring (34) is damaged or broken: Remove head assembly and
replace the damaged spring. Re-assemble, fill and bleed per page 6.
