Default Air Ride Forks

I am going to be replacing the sliders on the forks soon. In reading in the service manual, there is no mention or picture of any parts that make the air ride fork different than a non-air ride fork. Other than a mention of draining off the air pressure and removing the "banjo" fitting.

Is this all the difference? Seems like there should be a piston or diaphram inside the tube to keep air from being entrained in the oil?

Good question , went through my manual and same , rear shocks are air shocks but front looks like they are just adding air to the tube through the top caps?

Default Maybe Moco Left Something Out...

...wouldn't be the first time.

Maybe someone has been into one of these and will chime in...

I just took mine apart this winter on my 97.
There is nothing there except what you mentioned, the air just goes in the fork tube.

By the way fyi,, when you're putting it back together, the "banjos" remain loose even with the banjo bolt tightened down.
I mean the banjo will still swivel when the bolt is tight.
If you try to tighten the bolts to lock the banjo, you will snap them, they're made from putty best I could tell.


Bet you can figure out how I know this.

I suspect the springs may be slightly different, but otherwise I think you're right. I'm gathering the parts together to rebuild my 'air forks' into non-air forks. The air mixing with oil is a feature of many suspension systems, if you see rear shocks described as 'emulsion' they are the same. Our forks, air or not, are very rudimentary, as far as damping goes!

Default Thanks Johnod and grbrown..

...for the tip on the banjo fitting tightening and info on my primitive forks.

So grbrown, why are you changing from our Air Ride shocks/forks to what? Progressive gas inserts?

I'm not doing things by halves! I'm using a CCE Tour Trac forks kit and Ohlins cartridges, plus Brembo calipers with a 2010 SG front wheel.
