QUOTE=Bigd9;5602279]Well, I remove the 22.5 inch tires on my coach using a torque multiplier and a tire dolly. Lugs are torqued at 450 ft-lbs and tires weigh in at over 200 pounds. The tire dolly makes easy work out of removing and installing there tires.[/QUOTE]

Hello,

Would you happen to know the formula for setting the torque # on your torque wrench during the install?
IOW what number setting is on your torque wrench when re-installing your wheel?

Thanks for responding!

Our rig has 22.5 Alcoa's torqued to 450 ft lb as well.
I carry a small Chinesium torque multiplier kit complete with sockets, including the square drive socket for the inside rears. Those cheepie torque multipliers work amazing. This coming from someone who has about $30k invested in Snap-On and Mac tools. I also carry a three foot 3/4" drive breaker bar, 16" extension, a three foot cheater bar and a short handled flat blade shovel. Use the shovel and one wood leveling block to lift the wheel/tire on to the hub studs, ezpz.
We had those tire Dolly's in the shop and they work great, just not practical to carry in the coach. The shovel on the other hand is a useful tool. As far as final wheel torquing is concerned the breaker bar with cheater pipe extended to about four feet and about 100 lbs of force will get you very close to proper wheel torque. I don't carry a "rack" to support the extension, but you guys have come up with some amazing contraptions.....

Yep,
When in the garage, one can have all the quality and can correct tools for a given job. But, when out in the field or traveling, most of us have to become *MacGyver* in all sorts of ways. Ya do what ya gotta do, to get the job done. period.

I'll never try and change my tires on the road, as I'm getting too old with back issues. I have pulled my duals off while at home to add shocks and repair a flat. I just use an automotive jack stand to balance the breaker bar. The height is adjustable and the top is flat and works well to support the breaker bar.

From my 2006 Ford service manual.

With the weight of the vehicle on the tires, tighten the wheel nuts to 224 Nm (165 lb-ft) in the sequence shown.

You could also use a jack stand to support the socket extension.
Or a bottle jack that will be used to lift the axle once you have the bolts "cracked" loose.

To calculate tightening torque with a multiplier:
Research what torque you want it to be at...Let's use 450ft lb for the example.
Determine how much multiplication the multiplier applies. You can look at the specs or rotate the input to determine how many turns it takes for the output to turn once. Let's say it's 10times.
So, add 10% (look at the multiplier specs) inefficiency. So, you are targeting 450 X 110% or 490.
490 / 10 = 49 ftlbs at the input to tighten the bolt 450 ftlbs.
No grease on the bolt or nut or you have to reduce the torque to get dry clamping force (bolt stretch) to spec.

Best is to put a torque gauge on the OUTPUT of the multiplier to get true torque. But if you don't have one, the above will work until you get a heavy duty torque wrench to retorque in 50 miles of driving.

I bought this torque wrench adaptor when I changed some tires recently. It’s 3/4” drive and fits on the end of my breaker bar. It worked well when I torqued my lungs to 450 ft lbs.

It might even fit on the end of a torque multiplier. I used a breaker bar with 4’ jack handle to break my lug nuts loose

I like the different ideas for tools to hold the extension straight. I used a jack stand when I did mine, but now I’m going to have to build a tool for it.

I have a spare tire for my coach, but I still need to find a rim and get it mounted.

Very cool. Thanks for sharing. I carry all the goodies including an unmounted spare. I have a tire hammer and 2 tire irons. I'm pretty sure I can change the tire out on the side of the road, but haven't had to prove it to me or anyone else yet:-) I busted thousands of tires back in my first life. LOL

I have no experience mounting tires, but it looks like a plain 22.5x8.25 rim is only about 100 bucks. I’ll just get it mounted and carry it that way

Hey, where do you keep the spare tire on your coach?

I had a guy make an extension with a vertical pole that goes into my trailer hitch. If I need to open the 2 doors, its just 2 bolts that hold the tire on to the pole, or I can slide it back 5-6 inches and barely open 1 door at a time:-)
