IT runs a pair of bronze bushes for the mains with an oil gallery machined inside for lube but the big end is made as bearing shells but in bronze (2 halves).

Nice mess in here to clean up. Believe it or not the pipe is on top of the governor shaft and it is as free as a bird to operate.

This is where it is at now. I removed the hopper which took some doing as the gasket had a good hold on it. The 3 bolts that held it in place snapped off due to rust, surprise. Then I started digging out the rust from around the cylinder. So far I have remove 2 x 2 litre ice cream containers of loose flakey rust and this has got me half way down past the bore with a lot more to go. At least now I can see the small brass elbow to connect the oil primer line to now. Next was time to remove the crankshaft. I undid the nuts on both side covers and got one cover to move away fairly easily but the other side where the gears and oil pump are was a bit more tricky. Eventually it let go to expose a huge mess inside. Because this engine has not run for many years everything in here was dry as a  bone to a point that it was almost carbon black again. It was very thick so I scraped a lot out and wiped the ends of the gears to find the timing marks from the crankshaft to the cam. There are no timing marks for the governor or oil pump. I mention this because I have come across one engine that required the oil pump to be timed with the spark of the engine and this was the David Brown 30C engine. It had to be timed so the offset tang of the distributor would engage with the oil pump.
Next it is time to remove the gears and get inside for a clearer look.

Thought I would start this off here now to give me time to gather up the parts that I know are missing or stuffed for the SE Imperial Super-Diesel rebuild.

1 - Complete oil primer system. It is a small cylinder that sits on the RH side of the engine when looking at the head.
2 - Fuel tank to suit this engine.
3 -Gib keys x 2 off measuring 1/2" wide x 3/8" thick x 3 1/2" long
4 - Head gasket. Parts list 1 gasket and 4 "O" rings but later mentions 2 gaskets.

A detailed picture of how the governor is suppose to be set up. Mine arrived in pieces and sith no idea of how it should go back together. I have the 2 weights and 1 pivot pin but I can make another one of those but it appears that the weights stay put but simply spin in that position and the shaft that goes across to the governor has a spring that is adjusted by turning the wheel on the outside of the engine and I am guessing more or less tension is all that is required to adjust the running speed.

This is a start, so any info or leads will be gratefully appreciated.

My thoughts were that '' pobge '' probably referred to ''podger'' of which I also have a couple of in the workshop. However the spelling had me intrigued, so I wanted to check out the true meaning of this mystery tool. Thanks for the clarification.

The podge is similar to a metal punch but has a long taper with a rounded end. It was bought when I was playing panel beater and was used to align bolt holes. Probably has 6 other names but this was what it was called way back then.

Well done again,patience and persistence have paid off.
By the way, gibb should be spelt gib, and not as in the brothers.
Perhaps you could tell us what a ''pobge'' is ???
