just been passed a badly damaged CB550f speedo to repair, apparently the bike fell off a fork lift truck. Now this speedo isn't as I understand it the usual Nippon Denso one, it's a Nippon Seiki one and whilst at first glance they look the same
they are not. The body, face, internal mechanism and base are all differant. I have a base, straightend the inner and outer bodies so that's sorted. What I need is a dial face, a ND one is the same size but the holes in it that secure it to the mechanism are two close together and the apertures for the mileage counters don't line up.
To aid identification the face has Nippon Seiki Japan on the face, a side trip winder and a trip knob that can't be unscrewed. Anyone have the same type laying around in any condition?

Hi Kent,
Is this any good? It is actually for a 400, but sounds the same. Let me know if you wantt any measurements. It is a greyish green colour and does have an overlay fitted on it.
-
Thanks but it's the larger type as fitted to the CB750F not the smaller CB400F type. I looked on the U.S. site, a few CB550f gauges but they were all the Nippon Denso ones. Interestingly there's some dial face overlays listed for the Nippon Seiki type gauges, so if someone has gone to the trouble of producing the overlays for them there must be some around. Maybe that type were only fitted to USA models.

Hi Kent,
Is this the type you mean?

I don't have one (sorry if I got your hopes up!) but thought the picture might help people identify it, if this is the one you're after.
Cheers,
Steph.

Hmm. I bought lots of gauges from the USA for CB250/350K0's a few years ago (only need one set must Ebay the rest!!). The guy also sold me some 250K3/K4 and CB450 (metal cover type) and CB750 gauges at the same time and I seem to remember a 750 size gauge which was Nippon Seiki, which I found unusual for a Honda 4 and traced it to CB500/550. not 750. I can't remember if it was a Tacho or Speedo, sorry ! They are buried in my shed somewhere but I can venture in there if you wish.
Cheers... AshD

Thanks Steph 550 for posting the image, those are the ones. If you ever need tacho internals of that type I have two in my spares box.
-
Thanks Ashimoto K0, if you could have a look to see if it's a speedo that would be great. The image posted by Steph550 was great so maybe the Seiki type are not as uncommon as I thought. It seemed unusual to me to find the same model machine being fitted with gauges from two different manufactures
-
Has anyone got a trip reset knob for a 500/550?
-
If you can repair the faceplate it might be worth trying a decal off ebay £9
They are white background on the listing but he also does CB750 blue background. He could probably do a blue background CB550 on request?

Sorry Kent, looked in shed 1st thing and it was a MPH speedo and the correct size and Nippon Seiki but it must be from a CB750 custom like this one

Thanks for looking Ashimoto KO, not seen one like that before but I've seen ones with plastic needles. Bit of a nightmare those!
The original face has been bent back about 45 degrees and cracked into two pieces at the trip aperture. It's also distorted. I can print an overlay on vinyl so even if the lettering on the face is wrong I can resolve that. If I can't find one I'll probable make a face from some plastic sheet I have. It's just cutting the mileage counter apertures that's going to be tricky.

I have a complete set of large 550k3 clocks somplace in the loft of the shed, not sure if they are like what you are after, may have other clocks in the shed too (well, I know there are several sets of unknown origin and more again for bikes I don't own anymore, quite possible that same clocks were fitted to numerous other bikes - I'll take a note of what is on this thread and take a look, if something pops up as likely I'll let you know)
-
Thanks very much Matthewmosse, so much help on here! And thanks Oddjob for the info.
-
Well, found most of the clocks in the loft are Seiko - but not yet located the 550k3 ones - if you could let me know dimentions it might help as there are a few smashed clocks from which I can happily rob the faces, there are (should be if I can find them) 2 sets of k3 ones which are complete and fairly good order so breaking them up for a face might well be a bit costly - I might find a not complete set I'm hoping.
-
If you come across a decent working tacho I would be interested in it. Chrome bottom doesn't matter.
-
Hi,
If the Nippon Seiki one I found for the 750C custom is any use, I will break it up and let you have the face for 'nowt' as we say in Yorkshire. You could maybe do one of your overlays for it. If you want dims/ just shout.
You are correct as I have an ND one too for the same bike and the holes are further apart on the NS one and the apertures look different C/W ND one.
Cheers .... AshD

I did find a small face taco off a 500 (I think) and matching speedo (busted I think) but as far as I can recall the 550 had bigger clocks. Searching the loft is getting inpossible with the sheer ammount of bits in there, plus the state of the place, - the last straw being the lights have now fused so bear with me. If I'm taking an age, remind me via Pm's - the shed has a habbit of making me get distractedas it is so full of half finished projects.

Sounds like my loft.... Went up there last week, there's a battered 400/4 tank up there, I can see it but I can't physically get to it!! ;D

I think a diesel road roller engine, landrover gearbox x2 in bits and honda rebel 125 in bits was kind of too much, organisation became chaos, then Ihad to find bits for a bmwr90/6 that I'd agreed to sell as a runner (carbs and coils needed then) - now it looks like a bomb hit it.
-
I have two seiki guages. One blue, one green. Ill try and get pictures up but my internet is restricted until tomorrow. :-[
-
Thanks for all your replies. The diameter of the face is 90mm (same as the ND type) The mileage counter aperture is 27mm from the top and the trip aperture 26mm from the bottom. Both those measurements ignore the tab on the top and bottom of the face. The holes that secure the face to the mechanism are 26mm apart (ND ones are 21mm apart)
I'm working on plan 'B' and that's using a dial face from a Silver's replica. The holes that secure it to the mechanism didn't line up so I filled them with epoxy and drilled holes in the face to suit. Seems to have worked OK but the replica face is thinner than the original. Seems a bit too flexable to me and the apertures don't quite line up. Working also on the the overlay in photoshop.
The correct face regardless of what's printed on it will be a better option of course.
Take care in those lofts, my kids nicked the ladder once when I was up there for a laugh. Found some rope up there and made my exit using that. Then used the rope to hang the kids, well not quite but didn't think it could be an option!
-
It's not a problem stripping the gauge I have down, I will never use it anyway and you have helped me with advice in the past.
Cheers... AshD
-
Thanks Ash, I would think all Seiki gauges of the same size and with the trip reset on the side would use the same dial face. Only what's printed on it being differant. At the very least I'll owe your the postage cost. No great rush, pm when
convenient.
-
Don't worry about post costs, it's OK. Just PM me your address.
BTW, I am looking at a capacitance discharge micro spot welder for interconnection of NiCad batteries (if you solder them it reduces their life). Do you think if a gauge clamp ring was cut with a Dremel, it could be removed and replaced again and micro-spot welded or is the answer the Jubilee clamp around it and then de-crimping and then re-crimping. Trouble is I have not tried the re-crimp yet.
Cheers.... AshD

Thanks Ash, pm sent

Cheers for the PM Peter,
In a meeting at my new job most of the day (boring zzzzzzzz) so no chance to strip gauge but just stripped it down tonight but forgot to bring home my digital caliper.
However, measuring with steel rule, dimensions look pretty close to what you need and face has no cracks etc. Dunno how you are supposed to safely remove the plastic needle though, looks to be glued on to me! And trip knob has be left attached to shaft and threaded thro' grommet hole after removing mechanism to back-plate retaining screws.
Will get the missus to post for you tomorrow.
Cheers ..... AshD

Thanks Ash that's great, two tea spoons under the needle boss and resting on the dial face screws. Equal pressure on both spoons and the needle should just pop off.
Your discription of the trip reset mechanism leads me to be preatty sure it's exacly the required dial face. Oh there's no great rush. Thanks again.
-
Hey -- that's exactly what I used - two spoons-didn't mention it as thought you would consider me a bodger!!

Posted today pls let me know when you receive OK Peter.
The plot thickens though, venturing in my garage tonight, cursing the MG Midget that languishes unloved for 20 years and preventing me from my bike restos. I found all of my 250/350K /450K gauges (was a serial collector at one time, don't ask!)and there was a large one stripped down in a Jiffy bag labelled CB500/550? and its a Nippon Seiki one with a very crazed (hot climate) green face up to 120MPH but the wierd thing is that the trip reset comes out the back of the gauge not the side. So what's this really from, it's supposed to be a Honda one? 500T?
Cheers..... AshD
-
Ha, I'm looking at one right now. Is the trip on top and mileage below?
Oh this is perfect green face.

Yes that's it . What model do you reckon it fits?
Cheers ... AshD
-
No idea, I bought a few from Ebay I think. I assumed it was 750. Although I suppose the 750 has a higher MPH.
-
Thanks for the face Ash, it's exactly the same as far as the screw hole positions and mileage counter apertures are concerned.. An overlay on it and it will be a perfect job.
As for the 'bag of bits' found in your garage, could be an early CB550F. I took a look on ebay USA and I'm sure I saw one claimed to be CB550F that had the trip reset on the back.
Thanks again Ash
-
My trip re-set comes out the back of my CB550F USA import.
