I'm going to be changing my main wheel tires on my CJ in the next two  

weeks and

don't know how the split rim thing works.



Anybody want to take a stab at the correct procedure?



If not, can we talk about flight suits some more?

Prior to removal of the tire, wrap your flight suit around it so that it is

well protected for the flash fire that will surely occure when you start

cursing the tabs!

I do believe Dennis Savarese has tackled this issue on more than one ChiYAK

and can walk you through as can Doug Sapp and a host of others. I'm just

along for comic relief!

1- Remove the wheel assembly from the airplane

2- Deflate the tire by removing the valve core

3- Look at the valve stem and you will see a nut and washer holding the 

valve stem in place on the rim.  Remove the nut and washer.

4- Use two large screwdrivers or similar tools, insert the screwdriver or 

tool between the tire and outside rim.  Press down on the screwdriver to 

release the tire bead from the rim.  Do this in several locations around the 

rim until the bead has broken away from the rim.  Repeat for the other side 

of the rim and tire.

5- Once both the top and bottom tire beads have been broken away from the 

rim, place the wheel assembly on a suitable pad with the brake drum down. 

Now press the outside of rim down.  The two large semi-circular clips will 

release between the rim and the hub.  Remove the clips noting precisely 

which way you removed them.  They are not the same length from the notch to 

the end in both directions.  It is important when reassembling the rim to 

make sure one end of the clip is NOT extending over the valve stem area.

6- After the clips are removed, lift the outer rim up and away from the hub. 

Next lift the tire and tube up and away from the hub.  There should be a 

thin metal sleeve over the valve stem.  It has a 90 degree bend at the top 

with a hole in it for the valve stem.



Reassembly

7- Spread talcum powder or similar inside the new tire.  This will allow the 

tube to slide uniformly inside the tire when you inflate it.

8- Find the red dot on the new tire.  Insert the tube and align the valve 

stem with the red dot on the new tire.  Remove the valve core from the new 

tube.  Inflate the tube in the new tire to evenly spread the tube inside the 

new tire.  Allow the tube to deflate.  Again, check the alignment of the 

valve stem on the tube to the red dot.  Be sure to keep the rubber valve 

stem guard on the tube.

9- Spray some soapy water on the beads of the tire.

10- With the valve stem up, place the new tire and tube over the hub.

11- Next place the outer rim over the hub, being sure you align the notches 

of the rim to the hub.  These are for the big clips to fit into.  Once 

again, check the alignment of the valve stem to the red dot on the tire. 

Realign if necessary.

12- Place the metal sleeve back over the valve stem.

13- Place the washer and screw the nut loosely onto the valve stem.

14- Place the large clips on the rim making sure one end does not cover the 

opening of the valve stem.  The clip should not protrude at all into the 

valve stem cavity.

15- Press down firmly on the outer rim and while doing so press the large 

clips in place.   Once in place they will lock the rim to the hub.

16- Insert the valve core into the valve stem.

17- Inflate the tire making sure the clips seat properly between the rim and 

hub.

18- Tighten the nut on the valve stem to allow the valve stem to protrude 

approximately 1/2" or above the nut.



Any questions, please ask.

Dennis

Hey Dennis, et al ---



Don't have time to read the whole article right now but I do suggest you 

through those screwdrivers away. That is a guaranteed method of causing 

irreparable damage to the wheel.



If absolutely necessary you may use tire irons with great care (right shape, 

no sharp edges) but even that is usually not required. The right tool is a 

heavy dead blow rubberized mallet and maybe an extra guy to stand on the 

opposite side.



Later;

Walt

Hi Walt,

You're correct about the tire irons.  I have tried the supersized dead blow 

hammers and had no luck with them.  As an alternative I have taken the wheel 

assembly to an automotive tire store where they have the air driven tire 

bead breaking equipment.  It takes them about 2 seconds and they usually 

don't charge you any money because it was so quick.

Harbor Freight has a simple "Mini-tire Changer" for $39 that works  great.

 Thanks for the info.

Good description Dennis, but don't forget the 3 short little pins that fit UNDER the clip halves that align the 2 wheel halves. They fiendishly and steathily drop out on the hanger floor without notice!

Don't forget to use a  little MMO, or WD 40 or even Mouse Milk.  Makes releasing that bead a whole  lot eraser.

Well, OK, but make sure all that stuff is 100% removed before you install  the new tire. Must be clean and dry. If not you may find your tire rotating  on the wheel during brake application and shearing off the tube stem. Not good.  

 If you are re-installing the same tire don't do that.

 Good plan to paint creep marks on the wheel and tire after installation so  you can check for movement.

Are Yak-52 wheels the same?

Place the wheel on a piece of MDF board. Have a friend hold it and then 

guide you

to drive your car tire (tyre) over the sidewall rubber to rubber. Its what 

the auto

guys do when no bead breaker equipment is available......works every time 

and

the MDF prevents any scratching of the rim and the rubber to rubber is 

gentle

but persuasive.



kp



ps. bin those screwdrivers, Done properly no levers are needed.

If I'm not mistaken, they are only on the nose wheel hub  because the nose wheel hub does not have the square center piece on the clip  that keeps the rim from rotating on the hub.  The pins keep the nose wheel  rim from rotating on the hub.  At least that's true on the Yak  52.

Yes, they are.  Unless of course you have a 52W or TW, which have Cleveland 

wheels and brakes.
