Your 4x4 Traction BeadLocker™ Internal Beadlock is basically a low-profile tire located inside the existing tire. An inner tube is located inside the beadlock casing, which is kept inflated to 3.5 bar. The beadlock casing holds the inner and outer tire beads against the rim, preventing bead separation. The standard tire can then be deflated and inflated to any pressure below 3.5 bar, via the beadlock air channel. SAFETY Read the instructions thoroughly. Work safely! Let common sense prevail throughout the entire installation process. Wear hand & eye protection. Be cautious with compressed air. Use tire chocks before jacking the vehicle up and safety stands after it is up. Work sober! Keep these instructions in the vehicle for future reference, as others may need them to repair your tire. TOOLS REQUIRED You must have: 1) Tire Levers, or machine. 2) A valve puller to remove the old valve. 3) A knife or deburring tool to smooth the tire bead. 4) A valve-core removing tool. 5) A hand operated drill to drill and deburr the new valve stem hole. 6) 4 & 8mm drill bits. 7) Deburring bit, or 10mm drill. 8) NB!! A ¼” or 7mm spanner to hold the tube valve stem, while tightening the nut. 9) A 12mm spanner to fasten the tube- and air channel valve stem nuts. ! 1! MOUNTING SUMMARY The only modification required to install the 4x4 Traction BeadLocker™ Internal Beadlock, is to drill one hole in your rim (wheel) for the beadlock inner tube, which must be done correctly. 4x4 Traction cannot be held responsible for damaged rims due to drilling errors. The balance of the installation process involves mounting and centering the inner tube within the beadlock casing on the rim, seating the beadlock beads, fitting the special air channel and then setting the tire beads on the rim. LOCATING THE BEAD LOCK TUBE VALVE STEM HOLE TIPS By Harry Lewellyn 080709 This tip covers locating the bead lock tube valve stem hole. The first step in installing your bead locks is to select where to drill the hole for the bead lock tube valve stem. It should be located within 6 to 8 inches, left or right, of the standard valve stem hole and inboard as shown.

IMPORTANT: Before considering drilling a hole on the inside (brake side) of the wheel, be completely sure that there will be no interference between the brake caliper, disk or drum and the beadlock tube valve stem. Also, consider that you will have to get to the beadlock valve with a tire inflator or gauge. With a 25mm piece of regular wood pencil or similar dowel, stick it with chewing gum to the potential hole location on the wheel. Rotate the wheel to make sure that it does not interfere with the brakes or other inboard components and that you can get a standard air chuck and gauge on the stem. Check all four wheel-positions. ! 2! installation 1 DRILL AREA PREPARATION The beadlock inner tube valve stem hole should be located about 20cm circumferentially from the standard valve stem hole in either direction.
