Now, as always, Pics up first.
Before maintain the damper and shocks, let's check the swing arm first.
If not, you probably got something blocking the arm from moving. you have to check suspension blocks, pivot cups, arm pins to find out if anything broken. Re-lubricate them if needed.
If the Arm cannot swing freely, it will provide negative effect to the function of Shock/Dampers and Anti-roll bars, so do the weight balance and weight transfer.
Now, if everything going alright, let's deal with this damping systems.
After clean up, we have to squeeze the shock-damper to verify if it needs rebuild.
Put your ear close, if you hear bubble or friction sound when squeezing the shock. You are more than likely have to rebuild the shock.
First of all, release the spring by remove the down stopper cap.
squeeze to the very end then release, see if it can rebound back to pre-load distance. e.g. 10%,50% or 100%.
Well, if you set it up as 0% rebound, you don't have to do this test.
Pour out the oil inside, use shock shaft clamp to hold he shock shaft. Twist the shock end to release itself.
Be careful to not damage or scratch the shock shaft.
Then we put the O-Ring into a small bottle of silicone shock oil.
You don't have to take piston apart unless you have to replace with another type or it is damaged (highly unlikely). But you do have to verify if the shock shaft is bent. Replace if needed.
Now, let's carry on the rebuild process, as always, we recommend green slime from AE to seal the damper with best result.
Then tighten up the Alum Shock Bottom Cap.
Repeat the same process on each shock. Now we have all four shock-damper ready.
Suck the bubbles out with Damper Oil Remover, you could see the bubbles rising and explore quickly from shock body. Repeat the sucking process a couple times until you are sure that there is no more air bubbles inside by move the shock shaft up and down.
PS. If you do not have Damper Oil Remover on hand, never mind, move the shock shaft up and down to release bubbles and wait 5-10 minutes and then repeat. The purpose of doing so is to ensure the shock is fully sealed. Damper Oil Remover can make the whole process a lot quicker.
Final check out: we can squeeze the shock shaft to test the rebound of each shock. If it has been setup correctly, you will got same rebound for 4.
Set the spring back then all done!
Thanks for watching.
