Remote Reservoirs?

I've been messing with these since they are empty on air. I removed the shraeder core and attempted to push on the IFP portion of the RR's and pull them back out. I happened to notice while I was doing this that I was getting no oil whatsoever coming up from the tube that is attached to the shraeder tube. I lost some oil on the install of some 90* elbows today but it could t have been a while lot! I noticed that while I pull on the the IFP portion if the RR that the tube begins to draw a vacuum. Could I technically fill the shocks back up with oil through the RR? I would think so right? And if so how do you know when it's too much?

 

You would have to remove the IFP to fill the oil. The difficult part would be the reinstall the IFP without trapping any air in the oil side of the piston.

 

What he said
Also can I see a picture and can u tell me what year your truck is and some more info to make sure we got this all right.

 

These are non OE Sway-A-Way Racerunner remote reservoir shocks, they are fully assembled right now and the only thing left to do is top them back off with oil and air them up.

Only reason I ask if you can reintroduce oil through the remote reservoir portion by pulling back up on the IFP is because of the "sucking" effect I noticed it has with the shraeder core out.

So what you are saying is that I would have to remove the remote resi's off the coilovers entirely in order to fill them back up? I know with Fox shocks they say you can squirt the oil in with a syringe through the shraeder valve area with the core out through the same remote reservoirs.

 

If the shock has an Internal Floating Piston (IFP) removing the shrader to add oil does nothing.

You say remote rezzy shocks. I assume you want to not accomplish a proper service on account of having to remove the springs or are these rears with no springs?

If you want to do this as you suggest, via the hose, with the shrader removed, take the rezzy and fully bottom the IFP towards the hose. Through the hose end, push the IFP back 3/4". Using your syringe, fill the rezzy until full, fill the hose until full, join the hose and rezzy without fluid loss or air entry. Partial pressure the shrader and leak check. Complete shrader fill to pressure you prefer.

Not the best method but can work in a pinch.

Geez guys, speak english...

 

Good luck with that.

 

Actually, long ago, back in say 1977 when motocross bikes did not have rebuildable rear shocks, this is exactly what had to be done and worked fine.

Overall these truck shocks are pretty much serviced and bled the same way we have being doing MX stuff almost forever.

To do a proper bleed now on high performance stuff it is almost exclusively done with vacuum bleeds.

If the OP is careful, and takes a dab of quality grease to seal the hose and rezzy, he'll do fine

Without doubt though, it would be better to do a proper service.

They are not in bad shape though. These are basically new and I had to retrofit some 90*'s on them in order to achieve the same bolt on factory style the vehicle specific coilovers already are for the truck.



What I was talking about is immersing this tube in the oil container and basically pulling the assembly up to where it stops to get the oil out. These reservoirs are supposed to be full with oil?

Those look super clean. I'm sure they have never been off-road. Good buy

 

The shocks are a good find!

The reservoir is to be partially filled with oil. The remaining space on the air side of the IFP is to be filled with nitrogen through the shraeder valve.

 

Well everything is new about them. I bought the springs, extended rod ends, 90*'s, spherical bearings, and bearing spacers brand new. The actual coilovers were used as a mock up and only driven about 600 miles if that, and I got them for dirt cheap. About $300 for the coilovers alone, after it was all said and done I am in about $680 total maybe $700 flat for them. So I am very happy I got them!

About how much oil should I fill them up with? 1/4, 1/2?

I didn't lose a ridiculous amount of oil when I was installing the 90*'s but I still want to make sure that I have suffice oil in it for it to handle all of my needs as I go.
