Thanks Randall, problem Inhave is my shafts have bucket caps not screws that come out to remove shafts and bucket caps are no longer available , checking with Team Triumph by my house to see if they have any of those. Did you have screws or caps?

I was able to remove the bucket caps (aka bucket plugs) in good condition, by finding a tap that was just the right size to bite into the walls (sorry, don't recall the size offhand). With the tap in place, I removed the tap handle then dropped a short spacer over the tap (big enough to clear the sides of the bucket), followed by a flat washer and nut. Just tighten the nut to pull the plug out. Remarkably easy!

But then I decided not to reuse them anyway, and fabricated some screw-type plugs. Again I don't recall the size offhand, maybe 3/8" NF ?? Should be obvious, just pick the smallest NF tap that will bite into the sides of the existing hole (I did not use a tap drill). Tap the holes with the shafts out obviously, and clean up the debris.

Find a bolt of the same thread, and cut the end off square (if necessary) with a Dremel moto-tool and abrasive cutoff blade. (Wear eye protection please.) Remove any burr, then cut a slot across the width with the same blade. Depending on how wide your blade is, you may need to make a second pass to get the slot wide enough for a screwdriver. Then slice the plug off the end of the bolt. I was able to get all 3 plugs out of one bolt, but YMMV. Deburr the other end, and it's ready to go.

New O rings installed in gearbox top cover and spring tensions set. Waiting for bushing for reverse idler gear and then I can re-assemble. Engine going to be pulled next.
