How to remove auto oiler from Echo 352?

[Robert P]

My Echo 352 uses a worm gear that drives an oiler pump with helical gear teeth.

Anyone have insight into how you get the auto oiler out of the bore it's in? Both the worm gear and oiler on mine appear to be in good shape but I imagine eventually it'll need to be replaced.

Attached is a pic of one. There are threads inside the bottom end that's exposed on the end of the bore it's in. Are they for some kind a puller tool? Is there anything holding it in other than a friction fit?

Thanks!

It's a friction fit. Just put a screw in the thread and pull, or screw it with a spacer. Some Stihl have one too.

There must be a particular thread pitch.
