I am in the process of reassembling the forks and steering head of my 1967 Bantam.

I have replaced the bearings and bushes and now have a problem with re assembly. Looking at the top yolk, I have a “cup” to cover the bearing which will not lie flat but snags on a steering head fitting. The top yolk bolted in position snags on a fitting on the cross member and will not turn. So it appears I have to raise the yolk to clear the snagging.

All diagrams I can find, just show the cup and the yolk bolted down on it.......am I missing a nut to raise the yolk.

Did you strip the assembly? or are you assembling from parts? The parts manual will show you the correct sequence.

Hi

Thanks for your response.

I obtained my Bantam in a half built state and the rest in a weetabix box!!

I have studied the manuals as you suggest, but they do not show the fitting attached to the forward part of the headstock which prevents the “cup” sitting flush on top of the bearing, or the fitting on the top of the cross member which prevents the top yolk turning and thus steering. It just shows the bearing in place and then the cup over the top, then the top yolk and the final adjustment nut.

It looks as through the top yolk need heightening to clear the cross member intrusion and the cup so it sits flush and level atop the bearing.

i tried to upload some photographs to explain better my problem, but was informed that they were too large. I will try again if you think it would help and make the problem clearer.

Thanks for your interest

Mick

Just reduce the picture size to less than 1MB and it’s straightforward from there. A picture gives a better idea of the problem, at least 1000 words I’ve heard.....

Hi

I am about as much good at uploading and reducing the size of photographs as I am at rebuilding a BSA Bantam, but I will give it a go and hope for success and an understanding of my problem.

Im sure your just fine at rebuilding Bantams! Go to this page - [Permission to view this media is denied]
and click on 'browse' to find the image you want to resize on your pc. Then click on  'upload image'. When you have done that, click on 'download image' and it will save the reduced size image in your downloads folder. Easy Peasy and it takes seconds.

Good luck with the rebuild!

I'm baffled I am not sure if that is in fact a Bantam frame.

It does look like a Bantam frame but it looks to be upside down!

The steering stem goes in the other way.

The bottom yoke goes in from the other end. The bracket without the hole limits the movement of the bottom yoke.

 

D5 frame?

You have the frame upside down. The hoop for a padlock to secure the bike is on the bottom, not the top.

right come on then let us make the chap a bit happier ..own up to your best moment of madness. I'll start with trying to kick start the Sinnis with the stand down ..about two lost hours that was .. still I justify it as familiarization.

Tried to do the same start my bike with the stand down. Decided it was the switch fault so had to chisel the bolts off destroying the switch before I realised my stupidity and could just have put the stand up. So annoyed with myself bypassed the switch. That was three years ago and it is still like it.    We all do stupid things normally with me it is because rushing to get finished.

I had a mate pushing my AJS down the road with me on it, dropped the clutch to get it to start, after about fifty yards I realised I hadn’t turned on the ignition! I haven’t told him yet!

Hi 

I have always had the highest respect for a person who having made a stupid mistake, puts his hands up and admits to such stupidity.

I am the one with his hands in the air.........I was trying to fit the head stock on the D7 with the frame upside down!! 

I can only apologies if you feel I have wasted everybody's time, but I am not particularly mechanically minded and only bought the bike as a winter project.

Please don't think you have heard the last , I am about to reassemble the forks!!!!!

Thanks for all your help and advice.
