D9D 18A Recoil Spring Housing

So the recoil spring housing on my D9 18A is supposed to be filled with oil. One of them is currently filled with sand/water/oil/sludge. The problem is, I can't find a drain plug. The owners manual only talks about filling - nothing about draining. The tech manual makes no mention of draining either. I have scoured all around it and can't find a plug.

Is there a plug somewhere that I am missing? If not, how are you supposed to drain it? Will one of the bottom bolts holding the recoil spring assembly in drain the housing? Or can you only drain it when removing the recoil spring assembly?

There is no provision for draining, just fill and vent.

The drain plug for recoil spring is near the sprocket outside track frame

Any suggestions on how to clean it out?

Where is the vent located? That must be where the water got in...

There is no provision for clean out. There is a fill fitting and a vent/plug to allow removal of air bubbles when filling. The vent plug is only used during filling and then the plug is replaced. A contaminated adjuster would need to be dismantled to clean it out and normally any seals, sleeves, etc replaced then refilled with fresh oil.

Finally got the grease scraped off and found 2 drain plugs in each side of the track tension cylinder rod. Pressure washed the housing for most of an hour and seemed to get it mostly clean.

By chance are the track adjuster after market versions. My parts and service manual show the fill and vent plugs both located at the top of the cylinder flange.

I think we are talking about different things. I am working on the recoil spring housing, I.E. the track frame. The fill plug is on the rear, just in front of the final drive.
