Parts have arrived so I've had a bash, I mean how difficult can it be to tighten a nut?? well read on for two issues I have come across. First issue, the folding tabs bits on the washer don't line up with the nut. the one to the left looks fine, the one to the right doesn't http://s800.photobucket.com/user/martash2009/media/IMG_20161012_141303403.jpg.html Also there seems to be thread left on the nut which is not being used. It looks like because the washer is in place means all thread is not used. if that makes sense? if the washer was not used then there is no thread on nut left to use. see pic below. http://s800.photobucket.com/user/martash2009/media/IMG_20161012_141431091.jpg.html Probably explained all that really poorly, hopefully the pics will help. Trying to get this sorted myself today before the pick up tomorrow you see. Thanks.
