|  Filling Shocks?
Ok well i popped the tops off of 2 my wk shocks so now i need to put new oil in. I added ae 15wt oil to them and now they seem to be stiff and bind until i move them in and out a lot, that seems to free them up. Any suggestions as to how to fill them differently to get the binding to go away. When i filled them i moved them up and down until i didnt see any more bubbles, then i screwed the caps on. |

Sounds like you're filling them too full. Usually there's a rubber "bubble" in the cap, this is an expansion chamber. If you fill the shock too full, you'll compress this bubble as you tighten the cap (you can compress air, but not fluid - laws of physics) then there's no room for expansion left. The fluid will not be able to move through the piston and it locks the shock up. Conversely, if you don't add enough fluid, there will be too much air. It will emulsify as it flows back and forth through the piston, and turn the oil to foam. If the shaft feels "notchy" through it's travel, or you hear any "squelching" type noises, you've got too much air inside the body. Shocks w/ no piggy-back are finicky about the oil level...

when I fill mine I top it off, then move the piston up and down a few times slowly to get rid of air. after that I pull the piston half way out put the cap on loose and push it all the way up, this should expell excess oil that would otherwise do damge to your seals. with the piston up tighten the cap until the seal is just touching the body then turn 1/2 to 3/4 turns finger tight. do not crank it down. now you should have a perfect working shock. I do this the same to all my shocks and never had a problem. I change my oil every week regardless of how much it was used. it may not need it but I am anal about things.

Sorry to break in here and ask this, but you change your oil every week? Does the oil in the pistons break down fast?

I have never tuned shocks before, they are messy and better ignored, but I think i'm going to have to get comfortable withthe idea. so a heavier weight will help reduce the torque lean?

My knowledge of chemistry is a little limited, but it seems to me that it would take quite a long time for either petroleum or silicone based shock oils to suffer any kind of viscosity breakdown. In a crawler, anyway. You might change your shock oil every weekend if you're racing nitro stadium trucks or something. | |
