Topic: Re-attaching speedo trim ring

[Scott S]

 How are you guys attaching this chrome trim ring?

 It was loose at the end and I tried some 2 part epoxy. Then the whole damn thing came off! Super glue?

Check YouTube for how-to vids. There are at least a couple.

[Scott S]

 I found a couple that show them un-crimping and then re-crimping the main body ring but none of them showed this separate trim ring.

Thats because it is supposed to be in one piece, now its been cut the only thing you can do is glue it on.

 Super glue?

Doubt it, the only thing i know that sticks and then only temporary is fingers. I would use epoxy all the way round and hold it in with a big jubilee clip. In UK i would use araldite

[pjlogue]

With the ring being cut and pretty mangled I would buy a new ring.  You can order one here:  https://www.cb750faces.com/cb750faces.nl/

If you want to salvage the old one I would try and get it bent back into some usable shape and then use JB weld and hold it in place with a large hose clamp being careful not to have the epoxy ooze onto the clamp.  Once it sets you will never be able to open it again so make sure everything inside is working. 

The best way to open the gages is to use a old fashion pain can opener.  It's the best way I have found to bend up the underside (backside) of the crimp ring.  The hardest part is re-bending the ring back again to close up the halves.  I just rebuilt my gages for my GL1000.

Those rings are very hard to close. I have tried, gave up when lacking proper tooling pressing the ring tight.

I could not find a clamp thick and rigid enough to have around the gauges with ring on and squeeze it together with screwdriver

my needle wouldn't come off, slowly tried prying up, and the dayyyum thing broke right off......guess they are sh1tcan material now.......

I had the same issue since I had to open mine to refinish the gauge face plates. If your not looking to keep it OE, Joker Machine has rings that are 2 piece and clamp together with small bolts, like a pipe flange. Looks great, just not stock. Borrowed that image from JM website to show you.

Dolo - looked on the JM site but could not find the rings you mentioned. Could you point me to them? They look like just what I need.

[Dolomite]

This is the link to the JM website, they are a tad pricey. https://jokermachine.com/products/cb750-speedo-tach-clamp-rings-black. If you look around the interwebs sometimes you can find them for around $60. I got mine off fleabay from someone who was clearing inventory. They are well made though and look great.

Nice that people design parts making it easier. These rings will make it possible to service the gauge if needed. Possible to use as a quick solution until a tool can be made crimping the real rings together. On a modified bike as Café , chopper whatever the Joker rings will fit very well.

 I have NOS gauges with a very little use. since a month. Speedo needle jump around when riding.
I guess it is very happy to finally sit on a K2 it was made for after around 45 years on a shelf somewhere

I have a tool in mind using c-clamp that has 2 appr 25mm wide alu or steel piececs with correct profile squeezing the ring together. Start in one position and squeeze, then open a little and move sideways 20mm and squeeze again with a little overlap until it has gone all around.

I tried and failed. I even had a clamp. If I were to attempt fitting a ring again (not likely), I would make a tool for the job.

Perhaps you've already seen this how-to on the web:

 I used some JB Weld. It ain't the prettiest, but the repair/gap is at the bottom and shouldn't be too noticeable.

[Dolomite]

Found some photos of mine. I tried using JB initially but it didn't like to adhere to the chrome. I replaced the foam backing cups as well so the larger JM rings help to create tension against the foam "floating" the gauges more. Hope this helps.

I thought Marcel made new crimp rings? You would need a press with a die to crimp it on but it would look factory and last longer than epoxy.

This is what I had used on my CB350T, and it does leave quite a bit of waviness on the bottom of the chrome ring. On the small twin, the gauges face upwards, so the bottom is quite hidden. I think the bottom of the gauges on the bigger 4s are more visible.

Here you go

I have them as well.  Are they expensive, yes, are they worth every penny when you have get in and out of the speedo, absolutely

He does.

When did the faces on my 550 gauges I was able to pry the rings open to get them off and then crimp them back down with needle nose pliers. HOWEVER, I will concede that when you looked closing the rings were not crimped uniformly. Since my bike wasn't a show bike I didn't care, they held the 2 halves together and that was all that mattered to me.
