Mark Here's a pic of the adjusting screw. SDC14403.JPG There is a 'trough' inside the case which collects oil 'flung' off the primary chain. This trough communicates, via a hole in the rear chain case, to the 'trough' in your photo. The tapered end of the adjusting screw alters how much oil comes th...

John Below is a CP but just the same as BA Fit the selector mechanism in the main case. SDC14398.JPG Remove the 'locating bolt' from the outer case SDC14393.JPG Lower the outer case over the studs. Move the selector splined shaft as required so it fits through the case and the studs line up. Then wi...

The centre stay should be vertical from its mounting point up to the guard. The position of the angled rear stay, and therefore the location of its mudguard bracket, is therefore determined by the the location of the centre vertical bracket. The position of mine is verified in that the W/NG carrier...

Here are pics from my WNG. First is the rear bracket, second the centre bracket. SDC14386.JPG SDC14387.JPG The 'rivets' are small 6mm stainless coach bolts from Screwfix, with the heads reduced in size and 'flattened' a bit by putting them in the pillar drill and using an angle grinder with a fine g...

Joe Have a look at this previous post which may help you (my input is at half way down page 1) http://forum.arielownersmcc.com/viewtopic.php?f=4&t=7146 Re your question: the correct position is when the spring is fully would onto the bottom bracket (so the end of the spring comes up to the verti...

Mark, You really need to take it to bits so you can have a good look at the commutator. I think it will probably need machining in a lathe to get it back to a serviceable condition. You could try 'restoring' it with a strip of fine glass paper wrapped around it (don't use emery or wet and dry as the...

Mark As has been said the brush holders do appear to be grinding away at the commuter, which should have a smooth surface like the section which has not been damaged. I think you have the wrong brush back plate fitted, Yours appears to have been modified to 'fit'. If you compare it with the image of...
