OEM Split Rims ***Repair***

[JohnnyC]

there are several good threads...and one stood out to me and thought I would put some pics to it for a good reference.

I adapted a post by 'BULL' as seen here:

Patching Tubes




Steps
1. Remove wheel from vehicle

2. Remove any access air from tire (important)

3. Mark where the valve stem is on the tire for reference. Take a good look at how the ring looks seated against the wheel. It needs to look the same when you put it back on.

4A. With tire removed and fully deflated find an indent on the ring where it meets the wheel. Stick your claw bar in the indent and hammer it a bit so it digs in. Use the wheel as leverage and pry the ring up and away from the tire/wheel.

4B. If you have Tyre Plyers you may need to use them if when you put the tire together last you did so when the paint wasn’t fully cured as well as if the rim has some rust because this will prevent the ring from easily coming off with a claw bar…basicly breaking the seal that has been created by paint or rust.

I use wrenches to hold the bead from being pulled back in when i am breaking the rust/paint seal that has been created

5. Take your spoon bar and stick it in the gap between the ring and the wheel. Tap the spoon bar with the hammer and walk it around. The ring will seperate from the wheel.

6.Take the tire stem and push it through the wheel so it doesn't snag when you seperate the tire.


7.Pick up the tire and wheel and hold it at a 45 degree angle. Gently tap the wheel on the ring side. This will push the wheel through the tire. May take a bit if its rusty etc. You can use water or any type of lube to help it along.

8. Remove tire flap (a protective rubber ring the sits between the wheel and tube) If its there. Sometimes it isn't.

9. Remove tube air it up and spray soapy water on it. Find the leak. Patch using the scraper and vulcanizing fluid.
I found this in mine:

10. Now find the place where the tube was patched and use the valve stem mark as reference. Look inside the tire and find what caused the flat if you can. It may still be stuck or it was just a puncture.

11. Once everything is fixed remove the air from the tube and place in the tire noting the mark you made for the valve stem. Place tire flap in next. Make sure the valve stem is fully through the tire flap.

12. Place tire over wheel. Line up the stem and the slot where it goes through the wheel. While placinng tire over the wheel pull valve stem through slot. Now place rest of tire over the wheel a work its way down until flush.

13. IMPORTANT BEFORE PLACING THE RING BACK ON THE WHEEL MAKE SURE THERE IS NOTHING IN THE GROOVE OF THE WHEEL WHERE THE RING LOCKS. USE A SCREW DRIVER OR BRUSH TO CLEAN THE GROOVE. VERIFY THAT THERE IS NO DAMAGE (BURS, HAMMER BENDS, ETC). THIS IS VERY IMPORTANT. IF THERE IS DAMAGE TO THE GROOVE STOP NOW.

14.Now place the ring on the wheel. For reference start putting the ring on 180 degrees from where the valve stem is. Basically opposite side of the wheel. You want the split part of the ring opposite the valve stem. Force one side of the ring down into the groove once it catches start tapping the ring around the wheel until you have gone all the way around.

 

[JohnnyC]

15.IMPORTANT VERIFY THAT THE RING IS IN THE GROOVE ALL THE WAY AROUND TAP ON THE OUTSIDE OF THE RING TO MAKE SURE ITS SEATED.

16. Time to air it back up. This is where people get hurt if you haven't done it right. Tire shops use tire cages to air up split rings. You can do several things while airing it up. Wrap heavy chain around the wheel like a figured 8 making sure both sides are wrapped...my chain isnt quite long enoght to wrap in an 8...a single chain is better then none at all. You could also place it under your vehicle while airing up. Worst case when airing it up aim it away from you.

17. Put about 5-10 pounds of pressure and verify the ring is holding. Then air up the rest of the way.

It sounds like a lot, but it isn't just use comomon sense.

Thanks Bull for a great write up...if anybody has good pictures to add about repair...post them up


This is my kit for repairs

patches, rubber cement (tin) and animal fat (old truckers tip)

animal fat around the bead will make for a nice sticky seal...to prevent rusting on the bead area and help not having paint stick...i dont usually use it...put..i thought i'd throw that out there to those who may want to use it

 

[My wife said no FJ!]

Good stuff

Great post!

I picked up a set of split rims for my 40 this morning!

JohnnyC, are those Toyo M-55's? If so, how do you like them? Super expensive tire, but I've read a lot of good things about them.

and for the love of god be carefull.
if a split rim outer ring lets go instead of seating.....

 

[stuckinnz]

I just spent 1 1/2 hours in a tyre shop with the machine thingy for breaking the bead to remove 4 tyres off the rims when I've got them painted think I'll look for the animal fat to help with future removal(tried driving over them a dozen times to try and break the bead with levers in there as well, ended up in the press with a big hammer and bolster and had to go around a few times on both sides

 

[Living in the Past]

Nice read up Johnny. Poser (Steve) needs to make sure this get into tech. That way if I ever decide to use my split rims I can find it

I always wondered why they didn't design them so that the valve stem was on the opposite side of the rim from the split ring. That way, if you fill it while it's laying flat on the ground and the ring breaks away, it shoots into the dirt instead of decapitating the guy working the pump . . .

if a ring lets go while driving it will rip thru the brake line

the hardest part is breaking the tire off the bead I use these Tyrepliers: http://www.eco4wd.com/products/produ...TyrePliers.pdf

make sure the tubes have tr150 valves (see here: http://www.transamericanrubber.com/i...es/valves4.gif )..theybend nicely and are not too long not too short, the valve on the tube needs to be "off center" not "on center" as i remember my tubes were 750r16's

MAKE SURE YOU USE RADIAL TUBES AND FLAPS WITH RADIAL TIRES AND BIAS TUBES AND FLAPS WITH BIAS TIRES
