1977 GS750D/B UK Model Fork Rebuild Issues

[Guest]

I have a UK 1977 GS750D with spoked wheels and twin front discs.

I'm rebuilding the forks and some things aren't adding up.

Here's a model of how my forks legs, with components identified, were when I stripped them.

Problems I'm having are:

The thin lower oil seal is not shown or identified on any part list.


The steel seal spacer (in red) is not shown on the UK parts list, but it maybe shown on the USA parts list where two of them are used.


The slider bearing is not shown on any parts list.


So, what forks do I have and are they the forks that should be on my bike?

Hi, I know you list your bike as a uk model are you sure it is or could it have been imported? I have looked on Robinsons Foundry web site for a uk model it does not seem to fit your drawing https://www.robinsonsfoundry.co.uk/s...m#!gs750bforks

the links build up is pretty much like the gs850 forks as you say the slider bush is not listed I did find a link which I think is a Honda part but also listed as a gs750 part but you would have to take measurements to be sure.

I just went through this while rebuilding my forks. My 1978 GS750EC forks have the same setup as in your diagram. I ended up reusing the thin oil seal and steel washer/spacer.

The part shown on the OEM parts diagram (51168-30B00) is NOT the same as the washer/spacer in our forks. Our washer/spacer is thinner than 51168-30B00.

Pics coming in the next day or so.
