Inspection cover removal

Heat for sure. I use a couple of large coins or fender washers held together with large vice grips. Easy enough to get the leverage needed.

That's a handy wrinkle, I'll try it myself next time, thanks.

It's the diameter that out-leverages that soft slot. Large diameter threads are long shallow wedges; not short and steep like a small diameter bolt; large diameter bolts, have threads that are long and not steep; they "wedge" very well.
Anti-seize when it goes back in.

This is a good point, but if you are going to take off the primary cover eventually if other measures fail, you could always attack it from the rear. At some point the main objective is going to be to preserve the threads in the primary cover. Could always go to a belt drive and start cutting vents I guess!

Yes I was not thinking outside the box I guess. The other side duh.

LOL, me either until you mentioned the o-ring. Sadly it takes two Russes to make one good brain I guess. It would be my luck I'd finally get it off with heat and find a melted o-ring in the threads.

The suggestions are all good do try them before reading further. Failing those attempts I have two more suggestions:

1) I gather that you are ready to write-off the inspection cover, so find a piece of aluminum hex stock, 1/2" or 3/4", have it welded on the back side, apply a box wrench and have it.

2) If that fails utilize a Dremel to remove as much of the cover, where the threads are, as you dare, the point is to weaken the circular integrity of the cover so that it begins to collapse when turning force is applied.

The problem appears to be that the inspection cover and the primary cover have become, or mostly have become, metallurgically bonded. It may be to your advantage to live with it, especially if the cover is in good condition otherwise; they are expensive and used ones always seem to have the foot peg ding.

Best wishes.

<makes note to self to go back and apply anti-seize to the inspection covers on his recently rebuilt primary>

Probably find something dumb, Like the PO eliminated the 'o' ring altogether and JB'd the plug in. "Hell yah, now she won't leak!".

This is for real! If you should find something like this, don't get carried away and do serious damage to the cover. There is somebody here running a belt that is considering hacking up a cover to vent it. I guarantee it! So seek trades first or put it away in your kit for the day you decide to do this.

If penetrating oil is prevented from getting to the threads from the outside by an 'O' ring, take off the cover and put the penetrating oil on the threads from the inside. Heck, put it on both sides and apply heat from the inside. Maybe this has already been suggested. If so then apologies.
