Was out in the Bug today and the speedo did not appear to be reading correctly...could be that it is just awakening from its slumbers...20 odd years. The drive train is a standard Robin engine and gearbox with a B axle. The speedo fitted is the Bug 100mph unit.
Now the question what speed will it read...I think it may be reading about 30% LOW...ie 20 when doing 30. Does anyone know what the combination gives Bill
I had the same problem with my Bug (700cc engine ,std rear axle 80mph speedo) .It was reading the same as yours . I was going to get it re calibrated but then the milometer started to stick . I have seen pictures of my Bug fitted with a 100mph speedo and it has been suggested that it may have been the cause of it under reading as the 80 and 100 mph speedo's may have had different drives . I saw a 80mph speedo advertised which I bought to use while I had mine calibrated and repaired , however when it came it was in really good condition and to my surprise it reads at the correct speed so I still use it . I just wonder that as the Regal and Bug had the same speedo but different axles and wheels is this the reason ? The one that was reading low (and fitted to my Bug when I got it) had a chrome surround and the one that reads correctly has a black surround which suggests it was intended for a Bug as if memory serves me correctly when new the speedo fitted to the Bug had a black surround . I am sure someone on here will know the answer .
For Mum's day my daughter came out for a run and we averaged about 30mph. The Johnston Grass was bent fully over...must have been near the ton. Must take the Sat Nav next time...the mileage seemed about right B
Well, Took the Bug out for a run today and remembered to take the Sat Nav. Up to 20 mph the speedo is fine and generally follows the rate of progress, after that it sticks anywhere between 20 and 28mph. The mileage seems to be in the correct area, so at least some parts are working. The Sat Nav was much more reliable...now need to get a mounting point sorted out that the pilot can view, that is local to a power point(new one). The other problem is that one tyre has a slow puncture so will need to get some tyre goo around the rim. Other gauges NOT working are the temperature and the fuel. Not too worried as when on a group run if one stops for fuel everyone does...been there done that etc. B
My speedo works fine up to 40mph but won't go any higher. The top speed is @90mph with 750 and B axle. To cure this I bought a new speedo cable. This did not cure it. Anyone any idea what causes this problem?
heart nut, Not a clue, in my case the needle sticks at 25mph, it drops as you slow down but will not go any higher. The Sat Nav indicates around 55/60mph so the speedo is knackered. Use the Sat Nav now will be fitting a power point local to the mounting position to keep the cable tidy. B
Could the problem be with the speedo drive cable rather than the gauge? Due to it's position under the car and the age of these parts, maybe they just need a regular clean.
Then again, the gauges are from a 1950s Ford Prefect so it may just be fatigue. I've spoken at length with Biggles regarding the gauge cluster in the Bug -sorry Ron- and have found quite a lot of discrepancies.
The original Ford units seem to be painted silvery grey and have 'AC' above the word mph. Whereas the ones in Bugs seem to all be painted black with no manufacturers mark. I think they are either AC units modified slightly by Reliant or purchased by them with the changes.
I also thought they may have been made by Smiths but can't find any proof. However, a company called Richfield Speedograph seem to have a good reputation for recalibrating classic gauges and can supply new drive cables. Any company dealing with 1950s Ford 100e cars should also be able to help.
Sorry for the long-winded reply folks. I may be wrong on this but hope this helps.
If you have a question your better of starting a topic in the main forum.

mybug: Anyone know the whereabouts of PTO 365M? It was mine back in the early 80s and some pix have surfaced here (apparently from ebay around 5 years ago) so is it still around?

karl: Andrea, just seen your post. if you're still looking try putting it in the for sale wants thread.

mybug: Searched and spooled through every image/video/old ad I can find on the internet, I'm thinking that PTO 365M is not around any more. May be resting in a shed, but given the small and tight-knit Bug community, I'd have thought that someone would know it.
