    Posted: 28 Nov 2018 at 17:29
I've been hearing a metallic clank from the front end of my 70 Ambassador when I hit larger bumps or potholes and think I have found the issue. The upper part of my right side fork collar is detached and loose.

Every reference to the part I have seen shows it as a complete piece so not sure how it separated. I can rotate the upper chrome piece and separate it enough to get a small gap but can't get enough of a look with it on the bike to tell whats going on.

Has anyone experience this before, can the fork collar be repaired or do I need to find a replacement? I don't have the puller for this part so have not attempted to take the fork apart yet, thanks.

OH DEAR. That's not supposed to happen. I've never had any experience of such an occurrence on my Loops. I think the best advice will come when Charlie (Ambo Man) spots your post. As far as I know you probably need a replacement.

This might serve as a repair though it seems to be only an oil leak fix.

I did see that leak repair on thisoldtractor.com and thought it might be an option. I'm in the process of sourcing a replacement part and may go that route. It's not leaking on that side which seems weird though?

The seal is housed in the lower part beneath the break. Hence no leak.

I put the crashing noise / metallic clank over potholes down to the forks extending to the stops rapidly. Bit I've just had a look at mine and like yours one of the bits is a bit loose - it won't turn much more than a degree or two though.

Looks like I've more fixing to do!

I replaced the ones on my Eldorado with good used ones (from Charlie I think) Just because the chrome wasn't good enough for the bike. I still have the original ones in the shed somewhere. You are welcome to one if you need one in a hurry. Cheers John.

Thanks for the help and offer on the collar. I drained the fork oil last night so I guess I will take things apart and try to get the fork out using a dead blow mallet (never pulled these out before). Hopefully I can get the collar off with a strap wrench, if not I guess I'll have to buy the tool.

The chrome on mine is pretty good so I'll probably try to find a nice used one or possibly attempt the JB weld fix.

Since I'll be in there and have the front end apart should I go further and have a look at the steering head bearings? Those were on my radar before I figured out where the clunk was coming from.

How about fork seals, not leaking now but if I have the forks out would it make sense to go through the extra effort to replace those as preventative maintenance? I've had the bike for about 2 years but don't have much history on what was done before me.

You can check the steering head bearings for play in the usual way of pulling and pushing the forks fore and aft. Any play should be noticeable. But you can't tell if there's any good grease in there without dismantling. If it was my bike I think I'd do the full job including seals now that winter is upon us. Do you have a nice warm garage?
PS. You could re-pack the wheel bearings with grease whilst you're at it.

Do the whole front end so you know it's right then.

Well that's what I was thinking, I might as well go through the entire front end, thanks.

Thanks, I did find that link and got started last night. Not sure I like the looks of the grease/goo coming out of my bearings?
