Hi
The middle pinion in the timing chest can come out, just in case a seized camshaft or oil pump is stopping the crankshaft from spinning.

And, since it CAN come out, when it's going back IN, once correctly aligned, it should get a tight o-ring placed TEMPORARILY over the intermediate pinion shaft to KEEP it there! (remove just before installing timing cover, making sure it doesn't slip out of place)

I used a cable tie to an oil pump stud, even more obvious & hard to forget.

Hi
One thing that might be helpful to you now you have the timing cover off.
The crankshaft big end and main bearings will be dry after sitting for so long. It is not a good to try to turn the engine when it is like this. I think it would be prudent to get an oil can that can pressure feed and fill it with engine oil, then:
A) squirt oil into the main bearing on the timing side and on the drive side (primary cover off again) it is awkward getting behind the alternator, but you should be able to get some oil in there.
B) pressure feed oil down the centre of the crankshaft, by pressing the tip hard in the end feed hole, if it does not seal try a piece of cloth over the end, the oil should force through the cloth, but the cloth will help it seal. It will take quite a lot of oil to fill the sludge trap and work it’s way to the drive side big end.
C) lubricate the central idler pinion if you are having difficulty removing it to free the crankshaft from the camshafts and oil pump.
