I am trying to remove the forks of my 53 D1 and have come a but stuck.

I've loosened the bolts in the yoke and can move the forks up and down but there is a collar at the top of the fork which will stop it from sliding through the bottom yoke. 

Is this collar removable or am I missing something. The Haynes manual says to just slide it out but I cant see how that would work witht he collar in place.

I can't slide them up either because there is a grease nipple and a stud at the bottom of the fork.

Has anyone removed these before and could give me some advice.

Is there a better manual to follow as the Haynes one feels a bit generic and often does not provide any more detail than I could have worked out myself.

I got there eventually,

Some feedback incase anyone else is stuck here.

My dad suggested giving it a tap with a hammer so wooden block in hand and small hammer I tentatively tapped it and it moved.

The 2 rings at the top came off and the fork outers slid down quite easily.

Thank you all for your help.

We are a step closer to seeing the road again.

A-ha!

I did wonder, surely at the factory when they put it together they wouldn't be levering the yoke slots with big screwdrivers to make them go in? http://livinginthepast-audioweb.co.uk/imagex/misc/ohmy.gif

Hi

The parts you had to remove are no longer available and have to be made up, easy if you have access to a lathe not so easy if not

Since you now have 2 of the elusive 90-5029 top yoke seating washers in front of you, it would be great if you could take some measurements, they are number 36 on the diagram

cheers
