Staun Internal Beadlocks Install

[holeski]

Wouldn't it be perfect if we could apply high pressure right at the tire's beads, independent of the pressure in the balance of the tire? Staun's Internal BeadLock™ does exactly that. It is literally a specially reinforced mini-tube right next to the bead.

 

Very simply put, a Staun Internal BeadLock™ divides the innards of a tubeless tire into two air chambers. The one nearest the beads holds rubber to metal. This means the remainder of the tire's air space can confidently be inflated or deflated to any pressure you desire bearing blowing it, up of course.

 

 

We installed a set or #SBLN151012 Staun Internal Beadlocks with 15x10 steel rims and 33x12.5R15 tires.

Wheel preparation and hole placement are critical to the success of the install.

 

Tools Required

Drill

8mm drill bit

Drill Punch

12mm Spanner (wrench)

14mm Spanner (wrench)

Special Replacement Valve (Included with beadlock)

French Chalk (Included with beadlock)

Valve Core Removal Tool

Deburring Tools (files)

 

You will need to start with a clean rim with no tire mounted. If needed, dismount the tire and clean the rim. If rock rash is present, file or smooth out with a flapper wheel on a 4-½ “ grinder. Inspect rim for trueness and suitability. Only one-piece steel or alloy rims can be used to mount the Staun Beadlocks on. Seek the help of an off-road or qualified tire shop if you need help. Holeproof Industries is a authorized dealer and qualified installer of Staun Products.

Mark the beadlock valve hole with a center punch. The best position for the beadlock tube valve stem hole is 6” to 8” (15cm to 20cm) circumferentially (left or right) from the standard valve stem and 1” to 2” (25 to 50mm) outboard from the center of the rim. As far inboard as practical, but not in the exact center of the rim.

Drill your pilot hole, then with the 8mm bit re-drill the valve stem hole. You should use some cutting oil on steel rims. Using a rat tale file clean the hole of any burrs. Ensure that the inside and outside hole surfaces are reasonably flat and parallel to accommodate both tube vale stem O-rings and less than ½” (13mm) thick. Make the deburr chamfer face no larger then 0.070” (1.8mm) to properly receive the tube valve stem O-rings. Both the inside and outside surfaces should be flat, clean and smooth to the touch. Make sure the outside of the rim bead area is smooth, clean and free of debris. A file and wire brush will help with this.

Using the chalk provide in the kit, dust the supplied inner tube. Also dust the inside of the beadlock case and the back of the air channel flap. Remove the old air valve. Fit the special valve included in the kit into the rim's valve stem hole. Make sure the groove runs parallel with the edge of the rim. Don’t over tighten, or the seals will be damaged.

Fit the back or inside bead to the rim, either manually or using a tire mounting machine. When lubricating the tire beads for mounting, do not use soap or detergents since they may re-wet and allow the tire to spin on the rim in use. It is suggested that only water or a window washing product be used. Using wooden blocks, or the help of an assistant, elevate the tire off the rim to give you greater access and working space. Insert the back bead of the beadlock case and move the air channel in line with the replacement valve. Minimize the use of tools to fit the beadlock beads over the rim. This may stretch and damage this part of the beadlock and void the warranty. Install the tube carefully starting with the valve stem being pulled though the drilled hole. Make sure the tube doesn’t come in contact with any rough or sharp surfaces. Feed the rest of the tube around the rim inside of the beadlock case making sure not to twist the tube. Place the O-ring, washer and nut on to the valve stem but do not tighten down. Place the air channel flap between the tube and the wheel. Ensure the tags are pulled up and sitting flat against the rim.

Install the rest of the inner beadlock case bead until in place, don’t worry if it is a tight fit. It will fit with some assistance, but do not over force it or you may stretch it. Run your hand around the beadlock and make sure the inner beads are sitting flat and are not folded under the rim or tube.

Next fit the outer bead of the tire, making sure you always finish at the vale stems. Pull down the tire bead and check that the air channel flap and valve stem are in line. Also make sure the air channel straps are not between the tire bead and the rim. They must be under the tire bead and between the rim and beadlock. Now tighten up the valve stem on the tube.

Using a remote air chuck, inflate the tube to pop the tire beads on the rim. Large tires fill slowly when compared to the relatively small beadlock tube. Get acquainted with the filling the beadlock slowly or you may burst. Never exceed 50 psi (3.3 bar) in the beadlock tube. If the beads do not seal with 50 psi in the beadlock add more air to the tire not the tube. Add approximately 30 psi to the tire after the beads have seated on the rim. Remove the valve core and check for good airflow through the valve. Completely deflate the tire, then remove the tubes valve core and deflate the beadlock. If you do not have good airflow the beadlock channel is seated in the wrong place and you must break the tire down and try again. If both the tire and beadlock deflated properly, reinstall the cores and inflate the beadlock to 50psi and your tire to its normal pressure. Tire pressure can be no greater than 5psi less than the beadlock.

The maximum beadlock pressure is 50 psi and must always be at least 5psi higher than the tire pressure.

 

Wheels with the Staun Internal Beadlock system look no different than any other wheel, except there is a second valve stem. They are street legal,

help to prevent blow outs, and act as run flats saving expensive rims from damage if there is a flat. Thry are able to be balanced the same as any other tire. Anthony Rizzo of American Tire & Auto in Fairbanks, Alaska helped us in balancing them.

Perfect balance with the Staun Beadlock installed in the tire. Mater of fact out of 5 wheels 4 took fewer weights to balance with the Staun Beadlocks than without them. Our ride home was 65% better than before.

I know this forum doesn’t support the format of the photos. I’m sorry, to see them you will need to copy the address and past it in the browser or visit us here

 

http://norakor.com/simplemachinesforum/ ... opic=188.0

 

You will need to register to see it though. Again sorry for that.

[Pete M]

I think it's the registering part that screws it up. Plenty of other sites where you need to sign up won't allow hot-linking the photos. :(

[holeski]

There I was able to make it so you can just click on it as a link and the photo will open in another window, but I can’t not insert them due to the file type the web hosting makes them.

 

No it works on some forums and some it dosen't. The photos don't have jpg. or gif. so on as a subfix.

[Pete M]

Gotcha. :D

[jared]

price on them?

[Rokhound]

Hey I was wondering about these, and without me bothering to read 7 pages of information... can you run normal street pressure in your tires with these, or do they replace the stem and leave the tires virtually pressureless?

 

Meaning, would they work on a DD?

[DirtyComanche]

Yeah, you can. They're meant for DD/not trail only vehicles.

 

 

 

 

I saw them in action on a chevy 3500. He was running about 5psi in the snow with them and didn't roll a bead that I saw. Of course, that didn't stop him from rolling the truck :roll: Silly fullsize guys.

[holeski]

Yes we run around 30 psi on the street. The beadlocks are kept at 50psi the tire can have up to 45psi in them.

[holeski]

The ones we used we sell for $162.00 each plus shipping.

[jared]

thats pretty cool, and not too expensive considering most other beadlocks rims are no legal for street use and cost more than that unless you weld them up yourself. i know the hutchison rock monsters start at about 400 a rim and they are dot legal for road use.
