ZX600 shock oil change: Difference between revisions

Line 2:

So, you got yourself a ZX600 shock for your 250, and now you realize it's at least ten years old, and the chances of the oil in it ever having been changed are slim. Here's what to do.

Let all the air out of the shock before you start. The Schrader valve works just like a tire's.

Let all the air out of the shock before you start. The Schrader valve works just like a tire's. Note, however, that the oil and air in the shock aren't separated. If you hold it at this angle, some of the oil will come out with the air.

The shock depends on orientation (how it's mounted on the bike) and the force of gravity to create a situation where you can add and remove air without venting oil. So, if you press the Schrader valve in while holding the shock sideways or upside down, then the air pressure inside the shock will be able to force oil out of the shock.

Use a 10mm wrench and remove the entire hose from the shock body.
