Posted: Sat Dec 03, 2022 12:26 pm
Can anyone tell me the total length of the 1909-10 steering shaft that the pitman arm mounts to?

You can always go to the encyclopedia section of this web site and find this type of information.
STEERING COLUMN
1909-1910
3500 (T900). (Cars under 34,600, December 19, 1910) 50" long. Brass gear housing was a riveted assembly with the column fitting. Brass quadrant. Levers brass-plated with black hard-rubber knobs. The pitman arm was oval in cross-section, and shorter than the later types used with the two-piece spindles. (The first 2500 cars apparently used a shorter and straighter piman arm than that used on the post-2500 cars.)
1911
3500C (T5005). Now 56" long but similar to 1910.
3500B (T900B). For Town Cars, 51" length.
3500D (T979). For Torpedo Runabouts, 60" length.
1912-1914
3500C (T5005). 56" long, on all cars. A new design, the column was mounted 3/4" lower at the firewall than in 1911, requiring a new steering bracket and a change in the angle of the column mounting flange. Retained was the brass quadrant and riveted gear case. 1912 was the last year for the hard-rubber spark and throttle knobs. These were eliminated during 1912 and the ends of the brass-plated control rods were flattened for "handles." Around 1913 the lower mounting flange was changed from a forging to pressed metal.
1915
3500C (T5042). The 1914 column seems to have been used in very early production, with some overlap when both the old and new types appeared at the same time. The new gear case was now one-piece rather than riveted design. Quadrant was pressed steel, painted black, apparently introduced during 1914 production. The gear case was polished bronze, not plated. The cover was much flatter than previous cone-shaped type. Levers were steel with the flattened ends now smaller and somewhat round, and brass-plated (although some black-painted rods seem original).
Factory Blueprints indicate that the new one-piece gear case was approved on September 5, 1914. On September 18, 1914 the steering gear quadrant was redesigned. The new quadrant was made from cold-rolled steel and was to be brass plated. Early types of the steel quadrant were made with the serrated edge folded up, somewhat in the manner of the earlier design. September drawings show the later type (without the fold). There may have been two versions of the earlier design quadrant; one made of brass and the other of steel. Both are shown on the blueprint.
