I've managed to sort out the tight spot on the drum, by backing off the adjusters, putting some emery cloth on top of one of the shoes then putting the drum back on and slowly winding the adjuster in a bit a time while spinning the drum. Took forever but seems to have worked.

Final question is on split pins with castellated nuts. Which way round is the 'right way' and why? Do you spread the legs of the pin around the nut, or along the shaft. I don't think it makes any difference so long as you have the right size split pin, but would be interested in opinions as it's something I've often wondered about.
If it matters what gear you’re in, the engine’s too small.

The correct way to fit a split pin is with the legs bent in the same direction as the bolt. The head will then fit inside the slot in the nut. The side of the split pin is then bent over the end of the bolt and cut off so that the end does not protrude beyond the thread. The other side of the split pin is cut off and bent back over the flat of the nut so that the end is in line with the tightening face of the nut.

The head of the split pin will not fit in the slot in the nut if the ends are twisted around the nut.
As I have grown older, I've learned that pleasing everybody is impossible, but pissing everyone off is a piece of cake.

They will if you use very small split pins... :D

But I agree...however, trying to get very tight pins out of a nut when fitted with the head in the slot can be very annoying if corrosion has set in. Leaving the head of the pin out of the slot at least gives you something to get your side-cutters on to lever the shank out of the bolt.

Either way, as long as the legs are crossed, twisted, bent or buggered, the nut isn't going anywhere.

I must admit that the aesthetics of having the spilt pin positioned with the head "inside" the castelations are better but the advantages for ease of removal when the head "sticks out" easily out weights aesthetics for me.
Correct rear brake use is scientifically proven to shorten stopping distances in EVERY road situation.

Show you know what you're doing and use your rear brake!

the head of the nail sits nice and flush on the nut and the other end can then be pointed whichever way you want.....smiley face smiley face !!
