It can be done but it is not easy, there is some one on the forum who will do it for you but I can't remember the name.
You have to uncrimp the chrome band and recrimp it afterwards

That rings a bell

Ok thanks for reply's

As Bryanj stated taking these gauges apart isn't too easy and has to be done with great care not mention getting them back together leaving no evidence they have been apart. I've repaired/restored more of them than I could recall but this year alone it's in excess of a dozen. I can provide details of how it's done via email. You do however need to be confident in your own abilities before you undertake the task. Dial face overlays are available and I can provide details of where the best ones can be obtained.

Hi,
There is an American guy on youtube rebuilding a Honda cb750.
"Hackaweektv"
On episode 40 it shows him rebuilding a revcounter with a new face.
It may give you an idea of what to do.
Hope this helps,Aly.

I think 750 is different to 500

Elveytwin has a CB550 Four so should have the larger Nippon Seiki gauges, the guide I have only covers the smaller Seiki gauges. I have written one covering the CB750F Denso ones that was published in the VJMC magazine Tansha a few years ago. A copy is still available from the club archive. Unfortunately my copy was lost when a computer failed.

Useful...see at 9:00 minutes ..Don't you just love Dino .. he shows it warts and all . It's Ok for the likes of me blabbering on but to commit to video is something else. He's much loved on the USA SOHC  site before anyone takes a pop at him 

I would use a big Jubilee style clamp to hold the 'form' of the bezel during removal. Plus someone on here had found a drainpipe fitting instead of his bit of wood with the correct ID.

Just been watching some of his vid, great to pick up tips from him

[kent400]

Watching the video I wonder if any eagle eyed forum members who have ever had a gauge apart noticed when the guy was assembling the tacho the rubber seal around the inner body wasn't refitted fair to say it has to be carefully pushed under the band and can be a bit difficult. Obviously the purpose of the rubber seal is to prevent ingress of water and once compressed prevents the possibility of the painted body being loose on the base. All Nippon and Seiki gauges of that type have a seal in that location.

Water getting into a gauge can cause some serious damage very quickly, the image show a gauge I took apart today but fortunately once the rust flakes the mechanism is O.K. The water ingress was caused by damage to the rim of the body that distorted the rubber where the glass fits. Maybe a pressure washer was used on the bike at some point.

Folding he band back using pliers isn't an easy way, get the band edge to pushed down a little by the means shown and then use a bench drill press with a piece of small round stock in the chuck to push the band edge down. Even one of those drill stands in which you can put a power drill in will do the job and there is no risk of plier marks on the band. It will also look a lot neater on the underside. As Ash mentioned a hose clip around the band before removal, you only need to left the edge a small amount before you can get some round nose pliers with one jaw on the inside edge of the band, and the other on the outside edge of the hose clip to bring the edge to vertical. Once the band edge touches the hose clip the base will come away.
