Hey now,
I have a set of 21+ WP forks with a 6500 spring kit installed that could use a service. I can not seem to find information on how much oil the internal cartridges require. I know the external tube requires 400ml. Could someone help out with the internal capacity?
Is changing the 6500 internal cartridge oil basically the same process as the right leg on AER forks?
It’s 165ml. You also need a special tool to remove them from the fork cap as the standard one that works for the air fork doesn’t fit. I think Race Tech sales it.
Yes the procedure is about the same. Ride JBI has a few YouTube videos on it.
You just overfill it slightly. Measure how far the piston goes down and fill up oil to that level + some. Mount it together.
Then compress the cartridge a few times. Make sure to poor out the excess oil that's stays in the top of the cartridge if you compress it in fully vertical mode. Otherwise you will have more oil in outer tube than you fill it up with.
Fill with oil, measure down from top of tube, roughly 135mm down, insert base valve, some oil will push out during assembly.
Thanks guys. I can work with that info.
