Default RHD Pitman arm

Hi Can anyone help with these two types of pitman arms. Both carry the same part numbers and are Ford stamped. The straighter of the two arms was on my model 48 and the curved one off my model 60, both are RHD. The English parts books doesn’t list any differences ie 48 3590. What’s on your RHD car?
Thanks John

My 34 Roadster (RHD) has the Type 1 Pitman arm with the knob on the end, which I am pretty sure is correct for the year. As it happens I am looking for another one for my 34 (RHD) Cabriolet restoration. I have a LHD one, but I understand that they are not symmetrical and the angle of the shaft is specific to either the right or left hand models, as is the drag link. Am I correct in thinking this??

The angle plus the orientation of the splines in the hole where the arm attaches to the sector gear.

In one of my service books there is a page on the different pitman arms available regarding setting the steering box and wheels in the straight ahead pos,there are different angles on the location of the missed spline in the arm to get this .

Yes, the drag links are LHD and RHD specific with the steering arm ends 180 degrees opposite one another and the grease fittings positioned to the outside in both versions.

My Model 60 has the straight arm. Car delivered in Dec 35 but the original owner's widow told me he bought the car that was on display in the Royal Albert Hall in Oct 35. She could be right, I have found a photo of that motor show and there is a black coupe on display.

I have a RHD pitman arm, and also a drag link. If you're interested, I'll take a look & see what the condition is.

My 35 RHD has a straight pitman arm. The car was a 85hp canadian built touring sedan.

In the USA the 35 pitman arm clocking on the sector shaft was changed 2 degrees. The change from the original to the modified 35 pitman arm reduced road shock and steering end play. It was used with the original style sector shaft only! This pitman arm also had the letters "RP" embossed. Both the original and the early modified pitman arm have the basic pat number 48-3590 the modified pitman had an additional suffix of RP. Later in 35 a new sector shaft was used (with identifing chisel mark on the threaded end and a hole for cotter pin) the RP style pitman was NOT used with this new style sector shaft. The attachment hardware for the pitman to the sector shaft also changed with the new style sector and a cotter pin was installed.

Canadian Oct 1935 Parts Catalogue covering 1928-35 years states that for 1935 part #48-3590 is correct for both LHD & RHD cars.
For 1933-34 LHD is part #40-3590, RHD is part # 40F-3590 the 'F' representing Foreign.
LHD & RHD draglinks for 1933/34 are different as the steering arm comes in on the opposite side.

For clarity's sake, my comments above pertained to JR48's question and are only applicable to '32-'34 model vehicles (and likely to Model As).

Don't model A's have a square attachment to the pitman shaft? Or is that maybe just early ones? (Ive never had a model A.)

Ted,

I believe that a Model A drag link is shorter than the '32 version (as is the '33-'34 version).
