i could use some help in determining and finding the correct speedometer cable assembly for my early 1911 touring. is the cable housing steel or brass? are the wound housing coils wide or narrow like the repro brass ones? are both nuts on the ends knurrled or one hex and one knurrled? any and all help is appreciated. cheers stu
Aren't the new repro cable housings made from horn tubing? That would be why they are so limp.
The housing is heavy steel inside a brass sleeve. Both's ends are knurled, brass, and identical.
Our car is a late 12 stewart cable steel case Knurled on the speedometer end Hex on the swivel end we also have 2 spares they are the same as what is on the car. 1911 may be different, the early cars some have a brass case. Cheers Colin
pardon my novice knowledge of subject.....i'm confused as to whether your referring to the housing of heavy steel as the steel link cable and the sheath is brass into which it turns? if anyone has a detailed pic it would help me with the nomenclature. thanks and cheers, stu
I am not talking about the inner links at all.
The cable housing has a heavy inner flexible steel sheath covered by a brass outer sheath. The steel links run inside the inner steel sheath. Sorry I am on the road until Saturday no pictures until I get back home.
thank you royce
i appreciate the clarification. i had no idea.
sounds like an impossible task to find an original assembly or parts to make up one. i look forward to see your pics.

What is the length, i have a few lying in the rafters i need to identify .
i believe the 1911 cable is to be 48"
Anybody have a 60" and plus brass cable?
This is an original 1909 - 1912 cable housing as described above on my '10.
are you running a brass gear on the swivel unit?
if so, is a little noisy?
The wheel gear from 1909 - 1911 was brass plated steel engraved with Stewart part number 22. The gear on the swivel is brass, engraved with Stewart part number 1. It does not make any noise that can be heard above the engine.
The swivel in my photo was only used in 1911, it is 2 1/2 to 1 ratio with a cast iron body.
That forged steel swivel was introduced very, very late 1911, and used on 1912 and 1913 cars.
It might be marked A-12 and B-12 or A-13 and B-13, or might have no markings at all.
What would have been used prior to the iron or steel swivel? I did not think there was any earlier 2 1/2 to 1 swivel? All the 1911 speedometers require 2 1/2 to 1 ratio.
There are no markings on it that I could find.
OK so I have the correct one for 1910, and the one currently on the car is correct for 1912. Good thing I don't need the 1911 version!
Like the print that Layden posted says, and according to Russ Furstnow's Speedometer book, there were two different Stewart Warner swivels used in 1911.
The first one introduced a grease cup on the top side of the input shaft side of the housing. The second had the grease cup on the end (in line with the input shaft) of the housing.
In an article Russ wrote for the Model T Times in 2011, Russ identifies actually four types of swivels.
Type #1 has the grease cup on the top side of the housing at the end of the intermediate shaft.
Type #2 has the grease cup on the top end of the housing near the end of the input shaft.
Type #3 has the grease cup on the side of the housing at the end of the input shaft opposite of the pinion gear.
Type #4 looks the same as #3, but the steel sleeves that they had run the shafts through was eliminated. All the 1911 Swivels used the threaded nut to hold the pinion gear on.
Type 4 is very similar to the swivel that was used from 1914 on.
All of the earliest 1911 swivels that had the steel sleeves were very brittle and often failed.
The forged steel swivel was by far the best, but was also expensive to make. In 1914 they re-introduced the all-pot metal (no steel sleeve) design (last of the 1911 type.)
The 1910 swivel had NO grease up.
Yes, correct, my 1910 1:1 swivel has a place to insert a pin style grease gun.
Your car should have knurled nuts on both ends.
