Commando Mk2a clocks

MK2A Interstate should have the French Vaguelia Clocks, seems the trip milage feature was seen as better for the Interstate over the Roadster. But if they were short of Vegliaclocks they would no doubt have fitted Smiths and these would be with the green globe but the later lined green globe not the earlier solid green globe.

Yes you can get the face changed as the ratios and internals are the same.

Thanks John. When you say the "French Vaguelia" clocks, are these the blue arrow ones ?. Cheers . John

Sorry to disagree but my unmolestedmk2a has the normal Smith speedo and revcounter, I would sugest it will depend on when your mk2a was manufactured.

Hi Alan

Thats interesting. I dont have the documents to hand to check exact date of manufacture( at DVLA), but I know it was definitely manufactured in 1974 as an Interstate Mk2a. The bike currently has been re-built and has a small green circle speedometer and a NVT tacho clock...

My parts book dated 1973 shows green globe pattern clocks, in both Smiths & Veglia. Part numbers & descriptions are

063790 â Speedometer head, (MPH) Veglia, C/W trip

063791 â Tachometer head, Veglia

062277 â Speedometer head, (MPH) Smiths

062279 â Tachometer head, Smiths

There are other part numbers for KMH Speedoâs

My parts book dated 1975, for MK3 models, shows NVT pattern clocks, again in both Smiths & Veglia, part numbers & descriptions are

065874 â Tachometer, Veglia, Interstate

065875 â Speedometer, Veglia, MPH, Interstate

065643 â Tachometer, Smiths, Roadster

065638 â Speedometer, Smiths, MPH, Roadster

Again, there are different numbers for KMH speedoâs & interestingly there is no mention of a trip in the Veglia, although in the picture it looks to have one.

Veglia clocks are deeper than Smiths & require a deeper instrument case/pod but Smiths clocks can be, & are often fitted to these using a pair of points cover pillar bolts to extend the mounting bolts so they reach the lugs on the deep caseâs. Most 74 MK2aâs Iâve seen have the green globe pattern & I think it wasnât until the introduction of the MK3 that the NVT pattern clocks were fitted. If you let me know which you decide to go for I can probably give you the part & model numbers for the instrument itâs self (shown on the face) so you will know what to ask/look for.

Hope this is of some help to you,

Hi Tim

The speedo clock is a small green globe version with "Norton" inscription and "Made in France" on the bottom. Would I be correct in assuming that the is the Veglia Interstate clock face ?.

The tacho on the bike unfortunately is the NVT blue arrow Veglia (Made in France) version, so I guessI need to look out for the green globe Veglia tacho face to make both equal ?. I understand that trying to find these without purchasing the whole tacho clock is near on impossible however ?.

Hi John,

Yes, this is a veglia green globe speedo & should have the number 09190919900 after âMade in Franceâ. The tacho you require to match should have the number 09200909900.

Below is a list of speedo & tacho numbers that I have researched & noted over the years. They have been collated from many different sources including machines I have had through my workshop, internet & literature, so I make no claim that they are 100% accurate or complete, but I think they give a fairly good guide.

SSM 3001/02 1000- 150 MPH (1968-70) Solid Green Spot

SSM-3001/02A 1000- 150 MPH Green Globe Logo (best guess is that this is a replacement instrument number)

SSM 3001/03A 1000- 190 KMH (note, KMH clock but marked 1000 ?)

SSM 3001/04A 600- 240 KMH (this is from a spare instrument, original fitment unknown)

SSM 3001/09 1000- 150 MPH (1971-74) Green Globe

SSM 3001/10 600- 240 KPH (1971-74) Green Globe

SSM 4003/00 1000- 150 MPH + Trip NVT*

SSM 4003/01 600- 240 KPH + Trip NVT*

* These both have trip meters but in a Commando holder, there is no access to reset them so I think they may have been intended for Triumph Bonneville/TR7 Tiger. I donât have any info for the Smiths NVT style speedoâs without trip meters as per the parts book, can anyone help?

The 1000 & 600 at the end of the number relates to the number of cable turns per mile/kilometre, 1000 turns = 1 mile, 600 turns = 1 kilometer.

SMITHS TACHOMETERS 4:1

RSM 3003/00- 9k RPM Solid Green Spot (1968-70)

RSM 3003/12- 9k RPM (Solid Green Spot, found on Commando âSâ type)

RSM 3003/15 9k RPM (1971-74) Green Globe

RSM 3003/21(?) 10k RPM (1975-on) NVT

VEGLIA SPEEDOMETERS

09190919900 (1973-74) 150 MPH + Trip meter, Green Globe and 'Norton'

0919 091 9911 150 MPH + Trip meter (1975) NVT

VEGLIA TACHOMETERS 4:1

09200909900 9k (1973-74) Green Globe and 'Norton'

0920 090 9911 10k (1975) NVT

Hope this may be of interest to some & if anyone can fill in any gaps or add to my list I would be grateful.

Regards, Tim

P.S.

Alan,

Not so curious, both styles were available from both suppliers & by 77, bikes were being assembled from whatever parts they had to get them out the door to keep the receiver happy

Hi Tim

Thanks for this most comprehensive reply, acknowledging that the part I need is the Green globe (Made in France with "Norton" inscription, would be part number: 09200909900.

The irony is that I only require the dial itself as everything on my tacho is working perfectly ( other than its the incorrect dial...it's the NVT one whereas my speedo is the correct green globe one). I dont suppose you know of a source where i could simply buy the correct green globe dial as opposed to waiting for a full tacho unit to become available ?.

Cheers

John

Hi John,

Yes, the tacho part number you need is 09200909900. I don't know of anywhere you can buy just the face but I have had them converted or exchanged for the correct unit by A E Pople, so may be worth giving him a try, you will find his contact details here, http://www.speedorepairs.co.uk/

Hi Tim

Great....cheers mate
