Another question about speedometers

Post by madsundaysurvivor »

Hello,
Which is the corrects speedo for a B44vs? Please can anyone put a pic?

Really which are the differences between SSM5001/00 1600 and SSM5001/03B 1600? Size?
If I'm not wrong both are grey face and same ratio 2:1

Regards
nopdog

Not sure if it's original but from MY 1967 B44 Victor Special.
It's marked as SSM 5001/05-1000
I like it that it reads 150mph. In your dreams maybe.

Thanks nopdog,

:mrgreen: perhaps going down mount fujiyama with the engine in neutral.... b44icon
That is what I meant:
Bsa b44 - SSM 5001/05 1000
Triumph t120 67-69 - SSM 5001/06 1000

Both look the same, but really what is the difference between them?

Not used them but Classic Speedometers sell parts and on this page say: "if you don't see the part that you need please give us a call to discuss your requirements."

Hi,

The correct speedo for the B44VS is the 150 mph grey faced clock ( why 150 for a bike that can hardly achieve half that I have no idea....) This speedo goes with a 15/12 gearbox at the back wheel. A 120 mph unit could be of course be fitted but with a 2/1 drive box to suit.

With Smiths clocks the important figure is to the right of the model no, and it says 1000 or 1600 in these cases - this refers to the wheel revolutions per mile and determines which ratio gearbox to use so that it reads right.

Cheers,

Jim

I have successfully 3D printed some of the internal plastic parts because I could not find a supplier.

Thanks, alreay I have made the query.

I am doing a master on smiths speedos. This is my fourth week of home confinement and the only motorcycle part I have here is this old speedometer that is taking me out of boredom.

They're not cheap, and I haven't needed those myself so you will be testing!
I think that the reset knob metal and plastic can still be obtained as a spare, but there are some the wrong length.

I have also seen that the counter gears look like nylon, they are completely dry, they really need some kind of grease or this will only make them accumulate more dust

Nylon absorbs hydrocarbons and expands as it does so, best kept dry or use a dry lubricant like graphite.

Hello,
surprisingly I found a trip knob gear at home, in a small box with the remains of broken speedos and tachos
The vertical gear can be mounted horizontally, the plastic case / bracket has slots to mount vertically and horizontally, for me a discovery ...

Thanks crankbuster, I am still interested in the order, to have a replacement. surely when the confinement passes, at the moment I cannot receive ordinary mail packages in my city
