DESCRIPTION
The Cherry® G85D-S 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 “split” unit helps accessing tight areas and reduces operator
fatigue. Its durable, all metal housing makes this tool very robust for use
in a shop environment.
This tool installs all 3/16", 1/4" and 5/16" diameter Lockbolts® (any
material type) and 3/8" diameter aluminum lockbolts.
It can also install selected blind bolts and blind 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.

may be attached to any shop airline.
BLIND BOLTS
Insert the blind bolt into the proper pulling head until the head of the rivet is in contact with the pulling head nosepiece.
Insert the blind bolt into the application and pull the trigger to activate the tool; upon the release of the trigger, the stem
will eject to the rear of the 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.
BLEEDINGTHE SYSTEM
To replace a small amount of fluid in the tool, remove cap screw (31) and replace with the Cherry Air
Bleeder 700A77 & Adapter 700A86 as shown in the picture on the left.
Connect the air line and cycle several times until no air bubbles surface in the
bottle anymore while cycling the tool.

TROUBLESHOOTING GUIDE
- Significant fluid loss: Bleed the system to purge the air out. If performance doesn’t improve, or
Short stroke or low pull force
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.
- Broken or dislodged valve spring (item 59)- Remove and replace spring
Air leakage at the spool valve
- Worn or damaged valve spool seals: Disassemble and service the air valve
- Oil bypassing due to power piston displacement off its seat: Service Handle Subassembly
Head piston is slow or seizes
per instructions provided below.
- Clogged air muffler or filter Clean thoroughly with solvent and back-blow with compressed air.
- Pressure relief valve (items 14 through 19) malfunction: Remove, inspect and clean
components thoroughly. Replace seals and damaged components.
Head Piston (64) does not return fully - Return Cylinder Spring (46) is damaged or broken: Remove head assembly and replace the
forward even after system bleeding damaged spring.
- Seal surface between Return Piston (48) and Piston Rod Cap (75) is damaged or dirty:
Remove head assembly and inspect the parts; replace/clean as necessary.

SERVICE PROCEDURE
Caution:
・Maintenance and repair to be conducted only by trained personnel.
・Make sure the air is disconnected prior to attempting any repair or maintenance work.
Empty oil into a container by draining from head, hoses and power unit. Dispose of it according to environmental regulations.
Use a bent hook to gently remove the O-Rings, Quad Rings and Back-up Rings.
Use the protective caps 530A80 and 530A81 on the piston threads to prevent Seal 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.
Tighten the slotted nut (item 89) using a torque between 50 and 59 in.-lb. (5,65 and 6,67 N-m). Do not over-tighten as it may
damage the piston.
If replacing the Hoses (38, 39 & 40) make sure that they are assembled at the right location: the High Pressure Hoses (item 38)
at ports 2 & 4, Air Hose at port 1, Low Pressure Hose at port 3.
Before pressure testing, make sure that all the screws are tightened securely.
After service, fill and bleed the tools per instructions on page 6.
After removing the retaining ring and muffler (68 & 69), pull the Valve Plug (67) and Spool Assembly (61) using tool P1178;
It is not usually necessary to pull the Valve Sleeve (57) out. If it becomes necessary, use tool 837B740
When re-assembling, use tool 836B740 to push the Valve Spring (59) into its groove.
