Does anyone know what cars a 1913 model Stewart 2 1/2 to 1 LHD fits? I thought someone posted this in an older post but I can't find it again
LHD 's were used on TT trucks.
Canadian and other British empire vehicles, Japan, etc.
Isn't a 1913 a 2 1/2 to 1 right hand and 1959 a 2 1/2 to 1 left hand.
I don't know what you mean by "1913 2 1/2 to 2 LHD"? Are you meaning LH ( left hand) for left front wheel mounting or somehow LHD ( left hand drive) meaning where the steering column is mounted?
The 1959 which turns opposite from the 1913 goes on the left front wheel and was used by Chevrolet and others.
Do you have any documentation or pictures that show a speedometer drive on the left front of an American TT Ford?
I read it some where.At my age,you can't expect me to remember everything.
Layden, you are probably right. I'm not up on these. I was offered a Stewart 1913 RHD and another unmarked one that was identical but for the other side so I was just checking to see what it would fit.
You can swap the gears from a RHD to a LHD swivel and make them the opposite of the way the case was stamped by Stewart. At this late date you can't believe what's stamped on the case any more.
Stewart called the "1913" a RHD as was said above.
Here is a 1913 RHD Stewart swivel,
If you extend the pinion gear end and flexible shaft connection end as shown, both ends of a "RHD" Stewart will turn in the same direction when twisted. The LHD (1959 for instance) will turn opposite.

Pay attention guys!
Next question. The 1913 Stewart is driven by which front wheel, left or right? I believe it is for the right wheel.
If the 1913 Stewart swivel is fitted to the other side wheel for the drive, will that allow the speedo to operate as it should?
If the swivel input and output shafts rotate in the opposite direction, can such a swivel be used in place of the 1913, if fitted to the left front wheel?
Allan from down under.
The rotation of the Stewart speedometer drive is from right to left when mounted on the dash. The front right wheel rotation driving forward is reversed with the 1913.
The 1959 mounted on the left front wheel duplicates the same cable rotation direction at the head.
Do not use a 1913 on a front left wheel as you will be driving the speedometer backwards. Backing out the driveway is actually driving the head backwards but it is slow and is OK.
What Ken says is true if the markings match the guts inside the swivels.
You can check both rotation (RHD or LHD) and ratio (2-1/2 to 1) with the swivel loose as in the above photo.
