Sump Plug Problem

concours said:

Always a consideration. I also drill the bottom of my axle housing on my pickup trucks, tap 1/8 NPT, and use a below flush seated socket head pipe plug fitted with a magnet.

⅛ ! Crikey , 2 years to drain surely at least ⅜ , actually I have a knuckle dragging buddy, no pain in the butt he is , I couldn't talk him into welding a bung on the 9" housing on his all steel 34 hot rod, I bet he wished he had, ...... removed it 3-4 times for preload issues .

This thread has been good piece on what can or could or might or will happen.

My MK II magnetic sump plug has a shorter magnet shaft than the photo displayed by the OP. Maybe the previous owner cut it down? It is a clean smooth surface on the shortened magnetic stem, not a break.
And its the same plug used before the engine rebuild.
After this read I'm going to go in there and scope around anyway.

A strong LED pen light shining up into/through the magnetic sump plug hole can generate a lot of illumination from the bounce light coming off the shiny oil coated surfaces. Or bouncing the beam into an inspection mirror can work as a directional light source. Helps the scope "see" better.

I use Dowty washers instead of copper for the small and large drain ports underneath, no need to muscle up on tightening, they work very well stopping any leakage.

Good News! I removed the large sump filter plug and with a borescope attachment on the smartphone was able to see the magnet stuck to flywheel.
Then as recommended by Greg M. I jacked the bike up high on wood blocks, stuck my head under it and rotated the engine until the magnet was directly above the hole. I was then able to simply pluck it out with a pair of long nose pliers.

What a relief, I have two other bike projects underway and was less than thrilled about spending this Saturday pulling the head and jugs to access the sump and magnet. I will now put a solid steel bolt into the magnet hole. Thanks to all for the advise!
