No, they are the grease/oil pot filler caps from what I can gather, for the drive gears. I've attached a few more photo's, but I'm really unsure what I'm looking at. Still can't see "pawls" (?) The first is obviously the wheel from the side, and there is a slot or something, and a nut and pin with a threaded end that I've taken out but not sure what it does[Linked Image]
This one shows the inside of the wheel and a tab of some kind (part of the pawl?) on a seperate plate that at this stage I haven't been able to move (don't want to do any damage)[Linked Image]
This is a closer shot of the slot. It appears to be larger round holes connected by a slot, so I'm starting to think maybe this was wear the pawls went, and connected with the tab on the inside of the wheel. Does that make sense?
