Pedals out of line
Hej,
Really sorry to be a new poster asking for help but in spite of the rudeness of it I hope someone can still answer my problem.
I've recently moved abroad and so the only bike I've got here is a crappy old hand me down from a friend.
I've managed to fix most of the problems with it but quite a critical one remains- the pedals are out of line.
At first I thought the sprocket was warped but on closer examination the entire crank (I think this is the right English word) is loose. Sometimes its perfectly fine and in line and works but as you pedal it makes its way out of line and locks up.
How (is there any way?) would I go about setting the pedals in place?
The bike is just a standard Dutch cycle (which is odd to find when I leave Holland...), no gears or anything and pedal backwards to break.

It sounds like you might have a one piece crank. Info on servicing that is available here:
https://www.parktool.com/repair/readhowto.asp?id=150
While it shows a number of specialized tools, you can make due with basic hand tools. If your crank isn't like this, either post a picture of the area giving you problems or search the Park Tool site for more info. And don't feel bad a bout asking for help, that is what this forum is all about.

Do you mean the crank has "play" in it-- that is can "wobble" back and forth in the frame?
If this is the case you want to tighten the left side cone. Take off the large hex lock nut. Then remove any loose spacers. You should now see a round disc-shaped piece of metal in front of you with some slots in it. Take a flat bladed screw driver and tighten it (turn it COUNTER clockwise b/c you're on the left side). Tighten it until you have no play left, but the cranks still spin freely.

Thanks, I'll have a investigate about this later and report back (just keeping the thread bumped for now so I don't lose it too much)
Loose spaces- these are the ball bearing type things?
Where would this hex nut thing likely be found? The pedals seem to just join into the cylindar in the middle with no nuts connecting them.
I will take a picture if I can't figure it out for when I report back too.

The crank is definitely loose.
You need some grease in there, for gods sake.

A-ha!
A theory!:
Should the cover be the screw? Mine seems to be somewhat broken (on the inside). I'm thinking now that if I get a new one these and screw it on it'll keep that side straight (and so the other side with it)

As for the actual assembly / disassembly, you'll have to work through that. It looks like what would have been the large nut on Sheldons web page is what appears to be the lockring on yours.

This problem is more than a simple Internet solution. Suggest you find yourself a competent bike mechanic.

My suggestion is a full bottom bracket overhaul-- I would disassemble the entire thing and re-grease everything. I'd also suggest using bearing retainer sets rather than loose balls . You don't want to be trying to assemble loose ball bearings in the bottom bracket. This set up also looks a bit different from the usual American-Ashtabula set up. My suggestion is to take this one to a bike shop and ask them to overhaul the bottom bracket. You may well need new parts.
