Rockshox revelation

[Justin]

Hopefully someone else has had a similar problem.

Serviced the lower legs on fork as per usual.

 

After putting it all back together as per normal, I do notice that I am unable to compress the fork totally, it only goes halfway and then stops.

 

Makes no difference if the fork has air in or not.

I do find that if I turn the damper dial on bottom of the fork from min to max in increments and pump the fork the damper doesn't seem to "engage" at all. I.E. I dont get that sucking sound when it engages.

 

I remove the casing from the stations again and I tried to push the damper "tube" back into the fork and it only goes halfway. It kinda equals the same amount of travel i am getting when it all assembled.

 

I hope all of the above makes sense.

Had the same happen to me. Droo fixed it. Can't remember what the story was. Droo fixed it. That is all.

Usually that means the fork damper is overfilled, best to leave to a pro of you are not seriously comfortable with opening your fork up to its guts

[Justin]

Hi BaGear.. I have serviced the fork 4 times on the lower legs only,replace oil,foam seal only and didn't open up the damper so those levels should be ok.

I have done similar services on Fox shock and other Rockshox models and never had this issue after the lower leg service.

Sounds like too much oil somewhere in the fork. What Rev model is it exactly?

If too much oil in lowers it can be sucked/pumped into damper.

Maybe air in damper can cause similar problem.

Maybe the problem was there already and it was not noticed until service was done.

Something is causing the damper to go into lockout.

Revelation RL 120m solo air 2014- 2016 model.

 

Lower leg is the only oil I have replaced 5ml in lower legs per leg, according to Spec sheet.

The previous self services I did everything was working all ok, just this time it has decided to give me grief.

When I put the lock out on it locks the fork when I release the lock out I only have half of the travel

that can happen but very uncommon , the rev uses an emulsion damper ( or something like that ) there is already air inside it (very close ratio to the oil) more air would result in a "gap" in the damping or the lockout not working properly 

 

what the Op describes sounds like A classic damper that was overfilled but it could be somethign else 

 

best to crack it open and have a looksie inside

Will pull the damper out the top and see how much oil is in.

 

Will revert back if I can find out what is causing the issue.

You can't just keep doing lowers and expect everything to be fine forever - you're going to have to do a full rebuild at some point. Preferably around the 150 hour mark, which I'm guessing is just a distant memory.

 

I'm guessing that either the spring or damper have ingested enough bath oil to cause the hydraulic lock you're experiencing, which also means that your damper oil is contaminated with bath oil and whatever muck came with it from the lowers.

 

Do the homework - if you're comfortable with lowers it's not that hard, just keep everything properly clean and well organised, get the full rebuild kit and proper oil and grease (not red rubber) and make sure you've got a few hours and enough beer.

 

If it intimidates you, take it to Jacques at Cogent. He or BaGeara will get it sorted for you.

Ok... so I release the air on fork and in the removing the damper on the top of fork there was a release of air, removed the damper cartridge and slowly compressed the fork, which was previously not possible.

Reassembled it.

 

Pumped it up to pressure and the damper is now engaging as it should be..

Not exactly sure what was possibly stuck or if it was possibly the air that was causing the problem..

Seems to be ok now.

Thanks Droo.. I think it's time.

This will allow me to ride tomorrow but i will get hold of a service kit.. don't mind pulling it apart to service... thanks for the reply and advice.

[porqui]

Yep time for a full service
