CrossFire Installation

Just got Crossfires for the rear duallies on the MH and was wondering if they can be installed without removing the wheels, I have 22.5" steel wheels with the SS wheel simulators on them.
Thanks

You install them without removing wheels.
3 years and I like mine alot - easy to monitor pressure and adjust the air in the tires.

CROSSFIRE
The Crossfire can be easily mounted using only one bracket; however due to varying bolt configurations on dual wheels, one to three mounting brackets are provided depending upon the Crossfire model ordered.
INSTALLATION INSTRUCTIONS
Read directions before installing!
Parts Included:
  • Hex Bolt - Split-lock washer - One Crossfire - "How to read" decal
Tools Required:
  • Impact Wrench or Socket Set - 9/16" End Wrench, " Open End Wrench
To Install:
  • Inspect the valve stems and cores of the tires. Make sure all threads on valve stems are intact. If threads are stripped or stems are crushed, they will have to be replaced. Check and clean stem threads and cores of all mud and debris that might be present. Do not remove valve cores. (Do not use the valve stem extenders.)
  • Attach the hose with straight fitting first to avoid air escaping from the tire during installation, then attach the outside hose. DO NOT USE HOSE TO TIGHTEN! As you tighten the nut, air will begin to leak when the valve core is depressed. When the gasket bottoms out, air leakage will stop. From this point, tighten the nut 1 to 1 additional turns. DO NOT OVERTIGHTEN! This will cause shortened hose life and potential leaking.
  • Based on wheel type, determine which bracket to use.
  • Select the axle cap bolt or wheel lug bolt for Crossfire mounting; make sure hose easily reaches the valve stems of both tires. Do not put excessive pressure on either hose. Do not be concerned with the position of hoses; the swivel fitting at the valve allows them to self-adjust into proper position.
  • Attach the Crossfire valve to the bracket by tightening the hex bolt and split-lock washer with a 9/16" end wrench.
  • Mount the bracket onto the selected wheel bolt.
  • After installing the Crossfire, check all fittings with bubble liquid or soapy water to ensure there are no leaks.
  • Place "How to read" sticker on a convenient location. It allows anyone who may operate or maintain the truck to understand how the Crossfire operates.
  • Check valve with tire pressure gauge every 60 days to assure accuracy and remove any contamination.
  • If you have questions, please contact our service department, 800-228-0394, between 9 a.m. and 4 p.m. Central Time, Monday through Friday.

Yes, many people do. Then you only need one monitor for each set of duallies.

I read instruction too and I have new tires being put on this week on my 22.5s. Anyone have a better picture of how they would look after mounting? I have Alcoa classic on mine, but if similar wheels, a pic would help. Thanks!

I have seen these mounted in various ways including mounting directly onto the center hub cover portion of the S/S wheel covers rather then on an axle hub bolt or the wheel stud itself. When mounted on the axle hub cover portion of the S/S wheel cover what type of clearance does the mounting bolt cap have with the axle hub? I thought that was pretty tight as it was. I've seen that type of mounting done very close to the end of the hub (Pictured I hope, and I assume for stated clearance concerns) but I have also seen them mounted the same way nearly completely to the rear on that hub. I didn't like the forward mounting method as I would be concerned about it snagging something, particularly in a camp ground with low scrub bushes or anything else of that nature, or close contact with a high curb.

Any thoughts would be appreciated.
Thanks, Dan

I have steel wheels and the stainless insert and axle hub cap/cover. The stainless insert takes up just enough room so I could not bolt the crossfire to the lug nuts.
My solution was to rebend the crossfire bracket and drill 2 holes in the axle hub cap
on the end (or top ) and bolt the crossfire to the hub cap. It does stick out further than
using a lug nut , but is still inside of wheel . There is also enough clearance between cap and end of axle .. No interference with fastening bolts
Sure does make ckecking air pressure a breeze.

BTW ,, Cats Eye make a similar product
