Mid-Size and Small Cabin Corporate Jet Wheel: Tire Removal

REMOVAL steps……

NOTE: Before using the JetCraft Aviation Bead Breaker, consult your specific

“Aircraft Maintenance Manual” and or “Component Maintenance Manual” for all-wheel and tire breakdown steps and procedures.

NOTE: Confirm that work area surface is flat and level.

Step 1) Remove Cage arms quick release pins and rotate cage arms downward.  

Step 2) Measure wheel diameter - Slide lower blocks into place, evenly on lower crossbar and based on wheel measurement. Wheel needs to lay centered on lower crossbar (look down through the bearing hole) and make good contact on “upper step” of the lower block.

Step 3) Lay wheel and tire in accordance with lower blocks. Check for proper alignment by A) Ensuring the wheel is resting on top of all four “upper steps” of the lower blocks. B) Ensuring the lower crossbar section is centered when looking down through the bearing hole.

Step 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 center of sidewall on tire.

NOTE: If tire has water diverting chine, you can place upper blocks on top of chine, without damaging the chine.  

Step 5) Set hydraulic assist on top of the upper cross section. Place the appropriate size spacer in between the hydraulic jack and the top metal plate. Connect air hose.

NOTE: Double check Cage Arm fasteners, Lower and Upper sections to ensure the correct positioning before activating the Hydraulic assist.

Step 6) Apply pressure carefully until the tire becomes separated from the upper halve of the wheel.

Step 7) Release hydraulic pressure and remove hydraulic assist and spacer from upper crossbar.

Step 8) Remove Cage arm quick release pins and lower cage arms, remove upper cross section. Flip wheel and tire assembly over to break 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 tire.

NOTE: There should be no adjustments to upper and lower the blocks needed.

Step 9) Repeat steps 5-7 and remove wheel and tire assembly from bead breaker.

INSTALL steps……

Step 1) Remove Cage arms quick release pins and rotate cage arms downward.  

Step 2) Measure wheel diameter - Slide lower blocks into place, evenly on lower crossbar and based on wheel measurement. Wheel needs to lay centered on lower crossbar (look down through the bearing hole) and make good contact on “upper step” of the lower block.

Step 3) Lay wheel and tire in accordance with lower blocks. Check for proper alignment by A) Ensuring the wheel is resting on top of all four “upper steps” of the lower blocks. B) Ensuring the lower crossbar section is centered when looking down through the bearing hole.

Step 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 you have a good seat on the wheel and enough spacing to install the wheel retaining ring (split ring type).  For bolted wheels halves, ensure you slide 4 upper crossbar blocks to have a good seat on the wheel to compress wheel halves together to start the bolts.

NOTE: if wheel is too small for upper blocks to rest on wheel, upper blocks can be placed in center of tire. Tire can be compressed enough to start bolts.  

Step 5) Set Hydraulic assist on top of the Upper cross section and connect air hose.

NOTE: Double check Cage Arm fasteners, Lower and Upper sections to ensure the correct positioning before activating the Hydraulic assist.

Step 6) Apply pressure carefully until the tire is compressed enough to install retaining ring on the wheel (split wheel) or bolts with nuts (bolted wheel halves).

Step 7) Release hydraulic pressure and remove hydraulic assist from upper crossbar.

Step 8) Remove cage arms quick release pins and lower cage arms, remove upper cross section. Remove assembled wheel and tire from the bead breaker.

NOTE: After tire bead is broken from a particular wheel, it is recommended to place a mark or a line on the bottom block and label the mark for the wheel (i.e. Lear 60 nose, G-550 main). This will prevent having to measure wheel size next time you use the machine for this wheel assembly.
