There are a couple of ways to refill it....I chose a small funnel that fit tightly over the hole where the fluid is exchanged. Holding dampner a vise....pouring oil into funnel, work the assembly back an forth until ALL air bubbles are gone. You really need to watch for the extra small bubles that are hard to see.
Once satisfied....enjoy!
