Hi. I'm Eric from RockyMountainATVMC.com and today I'm going to show you how to change the oil and fork seals on a cartridge type fork.

To start you'll need some common tools and some specialty tools like the Motion Pro seal bullet, the Tusk fork oil level tool, Race Tech seal grease, tusk seal drivers and clean rags, but most importantly you'll need a service manual, which will contain the proper procedures for your machine. It will also list the appropriate oil level and type. Rocky Mountain sells a wide variety of fork oils.

First off we're going to back out the rebound, adjust the screw all the way, this will make certain that the cap fits completely back on to the damper rod during the reassembly. Now it’s time to thread the cap off the outer tube, and go ahead and slide the outer tube down. It's going to expose a spring, there is also a lock nut right there. You're going to pull down the spring and insert your wrench on the lock nut. This will also hold the spring down.

Go ahead and back the cap off the damper rod, and the lock nut. Go ahead and remove the spring, place it on your clean rag, there's also the push rod that's inside the damper rod. Pull that out and set it on your rag.

Next we're going to go ahead and dump the oil out. Pump it a couple of times, make sure all of the oil is out. This makes a pretty good mess so it’s a good idea to have a good sized drain pan to do this in. You want to go ahead and pump it until you can feel that all the oil is out of that damper rod.

Now we're going to go ahead and remove the dust seal. Flat bladed screwdriver, slide that out of the way, then inside there is the retaining clip, and once again use a screwdriver be careful not to scratch your fork leg. Slide the clip out of the way.

Next we are just going to go ahead and pop that seal out. Just go ahead and firmly use it like a slide hammer and it should pop that seal right out. Now we're going to remove the bushings slide your finger in, it’s a split bushing, slide it off.

Next we're going to slide off the other bushing. There's a flat washer in there. The seal. You notice there is a sharp edge right there on the end of the fork tube and we're going to pay attention to that when we reassemble. Then you have your dust seal and your retaining clip. Please refer to part 2 for assembly instructions.
