Jet Craft Aviation Universal Bead Breaker - JCBB-GSE-0007

The Jet Craft Aviation JCBB-GSE-0007 - Universal Bead Breaker is a universal aviation bead breaker designed to safely separate an aircraft tire bead from the wheel during wheel and tire maintenance, while also compressing tire and wheel assemblies during installation.

Jet Craft’s Universal Bead Breaker is built for versatility across multiple aircraft platforms, helping operators avoid stocking multiple single aircraft bead breaker tools. It is engineered to improve safety and repeatability, reduce technician effort, and support faster tire changeouts for MROs, FBOs, and private aviation operators. The same controlled bead breaking approach can also support industrial fleet and specialty vehicle maintenance teams that service heavy duty wheel and tire assemblies where controlled force and repeatable set up reduce rework.

Kit contents

• Universal bead breaker tool
• Portable, dismantlable design for transport and storage
• Hydraulic assist interface (uses shop air supply for operation)
• Wheel support blocks for lower and upper crossbar positioning
• Cage arms with quick release pins for secure set up

Features and benefits

• Compatible with multiple aircraft platforms (confirm per Aircraft Maintenance Manual and Component Maintenance Manual).
• Heavy duty construction built for long term use in hangar and field environments.
• Designed to improve safety and repeatability compared to improvised bead breaking methods.
• Portable for both hangar and remote operations where a compact GSE footprint matters.
• Helps reduce technician effort and speeds up aircraft wheel and tire maintenance workflows.

Operating overview

This aircraft tire bead breaker uses adjustable lower and upper block sets to support different wheel diameters, then applies controlled force via a hydraulic assist. For removal, the tool separates the bead from the wheel halves. For installation, it compresses the tire and wheel assembly enough to install a retaining ring or start bolts on bolted wheel halves.

Important notes

• Before using the Jet Craft Aviation Bead Breaker, consult your specific Aircraft Maintenance Manual and or Component Maintenance Manual for all wheel and tire breakdown steps and procedures.
• Confirm the work area surface is flat and level.
• Double check cage arm fasteners and lower and upper sections for correct positioning before activating the hydraulic assist.

Tire removal

1. Remove cage arms quick release pins and rotate cage arms downward.
2. Measure wheel diameter. Slide lower blocks into place evenly on the lower crossbar based on the wheel measurement. The wheel needs to lay centered on the lower crossbar (look down through the bearing hole) and make good contact on the upper step of the lower block.
3. Lay wheel and tire in accordance with lower blocks. Check for proper alignment by ensuring the wheel is resting on top of all four upper steps of the lower blocks, and ensuring the lower crossbar section is centered when looking down through the bearing hole.
4. Set upper cross section on top of wheel and tire, rotate cage arms upward and allow quick release pin to lock into position. In accordance with your tire diameter, slide the 4 upper crossbar blocks to the center of the tire sidewall. If the tire has a water diverting chine, upper blocks can be placed on top of the chine without damaging it.
5. Set hydraulic assist on top of the upper cross section. Place the appropriate size spacer between the hydraulic jack and the top metal plate. Connect the air hose.
6. Apply pressure carefully until the tire becomes separated from the upper half of the wheel.
7. Release hydraulic pressure and remove hydraulic assist and spacer from the upper crossbar.
8. Remove cage arm quick release pins and lower cage arms, remove upper cross section. Flip the wheel and tire assembly over to break the other side of the bead. Rotate cage arms upward and allow quick release pin to lock into position and set upper crossbar on top of the tire.
9. Repeat the pressure and release steps and remove the wheel and tire assembly from the bead breaker.

2. Measure wheel diameter. Slide lower blocks into place evenly on the lower crossbar based on the wheel measurement. The wheel needs to lay centered on the lower crossbar (look down through the bearing hole) and make good contact on the upper step of the lower block.
3. Lay wheel and tire in accordance with lower blocks. Check for proper alignment by ensuring the wheel is resting on top of all four upper steps of the lower blocks, and ensuring the lower crossbar section is centered when looking down through the bearing hole.
4. Set upper cross section on top of wheel and tire, rotate cage arms upward and allow quick release pin to lock into position. In accordance with your wheel diameter, slide the 4 upper crossbar blocks to the outer edge of the wheel, ensuring a good seat and enough spacing to install the wheel retaining ring (split ring type). For bolted wheel halves, position the blocks to seat on the wheel and compress wheel halves together to start the bolts. If the wheel is too small for the upper blocks to rest on the wheel, the upper blocks can be placed in the center of the tire so the tire can be compressed enough to start bolts.
5. Set hydraulic assist on top of the upper cross section and connect air hose.
6. Apply pressure carefully until the tire is compressed enough to install the retaining ring on the wheel (split wheel) or bolts with nuts (bolted wheel halves).
7. Release hydraulic pressure and remove hydraulic assist from the upper crossbar.
8. Remove cage arms quick release pins and lower cage arms, remove upper cross section. Remove the assembled wheel and tire from the bead breaker.

Best practice tip: After breaking the bead for a particular wheel, mark the bottom block position and label it for the wheel (for example Lear 60 nose, G 550 main). This reduces set up time the next time you service that same wheel assembly.

Tire removal

1. Remove cage arms quick release pins and rotate cage arms downward.
2. Measure wheel diameter. Slide lower blocks into place evenly on the lower crossbar based on wheel measurement by adding 1 inch to the wheel measurement. The wheel needs to lay centered on the lower crossbar (look down through the bearing hole) ensuring the outer wheel diameter does not contact the block upper step.
3. Lay wheel and tire in accordance with lower blocks. Check for proper alignment by making sure the lower crossbar section is centered when looking down through the bearing hole.
4. Set upper cross section on top of wheel and tire, rotate cage arms upward and allow quick release pin to lock into position. In accordance with your tire diameter, slide the 4 upper crossbar blocks to the center of the tire sidewall.
5. Set hydraulic assist on top of the upper cross section and connect air hose.
6. Apply pressure carefully until the tire becomes separated from both the lower and upper halves of the wheel. In most cases, the lower bead will break first, then the upper bead will follow.
7. Release hydraulic pressure and remove hydraulic assist from the upper crossbar.
8. Remove cage arm quick release pins and lower cage arms, remove upper cross section. Remove tire from wheel.

Tire installation

1. Steps 1 through 3, no changes needed. Lower blocks should already be adjusted from the removal process. Place wheel on the lower block bottom step and install the new tire on the rim.
2. Set upper cross section on top of wheel and tire, rotate cage arms upward and allow quick release pin to lock into position. In accordance with your wheel diameter, slide the 4 upper crossbar blocks to the outer edge of the wheel, ensuring a good seat and enough spacing to install the wheel retaining ring (if split ring type). For bolted wheel halves, position blocks to seat on the wheel and compress wheel halves together to start the bolts.
3. Set hydraulic assist on top of the upper cross section and connect air hose.
4. Apply pressure carefully until the tire is compressed enough to install the retaining ring on the wheel (split wheel) or bolts with nuts (bolted wheel halves).
5. Release hydraulic pressure and remove hydraulic assist from the upper crossbar.
