Arm(spindle steering) assembly. Left side.

MarB · Jan 31, 2020

I,ve installed a power steering (internal spool activated ) cylinder assy. on my Fordson Major Diesel , re-using the original left spindle steering arm. System works well and has lots of power assist. However ,, I find the steering would benefit from less steering wheel revolutions . Keep in mind the total number of steering wheel revolutions remains un-changed from the original non-power steering set up. I have done a bit of research in my parts manual , noting that the power assist steering spindle arm is a different part number( EIADKN-3133C) from the non-power steering spindle arm(EIADKN3133B) ( Left side ) . My question is ::: Is it possible the distance,, center to center,, of holes where drag link ball stud and center of splined area of arm where it fits onto top of spindle is shorter (or less distance), for the power steering arm assembly as compared to the standard steering arm assy. If so , that would account for as well as cure my seemingly excess revolutions of the steering wheel when making sharp turns.

I believe that it is probable. We used to lengthen the steering arm on the Majors, and early 5000s when someone wanted easier steering,
without installing power steering. It slowed the steering a little, but they were happy.

Thanks Skipper II for the reply. Interesting.. How did you guys lenghten the arm ?

Cut the arm off, beveled the edges real well, welded in a 3" long piece of steel,and ground it to the original contour of the arm. If I remember correctly we cut and welded a web into the angle of the arm.

Hi
I have a drawing in a genuine Fordson parts book and have seen some used arms on ebay for power assist steering. I'm not sure that the arms are a different length between the 2 for the Newer Majors like yours. But they are on the older Fordson E27N tractors that never had the option for power steering. I have both old and new type tractors here to compare them.
The last E27N i purchased has the wrong short new major arm fitted along with the matching newer axle. The only difference I see for your numbers is, The power assist type steering arm has an extra web cast across the corner between the 2 arms to strengthen it, doing the same job as what skipper wrote about.
My guess is those arms without the web broke with the extra force applied especially in rutted ground with a loader fitted as many were in the U.K.
