Difference between Major Diesel, Power Major and Super Major

[Billy26F5]

I suggest, that the purpose of the clip was only to keep dirt out and grease in; a modern (or Ferguson? ) rubber-booted ball joint might be more efficient, but I guess the slotted cap at the front can be screwed in to take up wear, so this type has almost eternal life, if kept greased?
And yes, the drag link for power steering is different:


The arm on icom102's future tractor ( ) does look closer to the chassis than mine, which has its axle at the narrowest setting; and after some research the un-webbed arm is about an inch longer, so yes, probably strengthened for power steering. So, has mine had power steering at some time (not as far as I can tell), or were all tractors fitted with the webbed arm after a certain date - which means icom's one has been replaced with an old-style one at some point?

That clip (E27N-3338) holds a felt seal (E27N-3336) to keep dirt out (on steering rams E51-LD-9 and E50-LD-9 were used for the power ball pin and manual ball pin operating the valve). These ball ends (not steering rams, only drag links) have shock absorbing springs (B-3327) which make for very pleasant steering on really uneven ground. Ford set them to fully tight minus 1/2 to 1 turn, but on Super Billy, before I had seen this instruction I set him to just touch the springs, and I really like it that way. E1ADKN-3304 was used till 1590283, replaced by E1ADDN-3304B with sealed ends (Dexta style, with rubber seals E346-JB-9). E1ADKN-3304B was used for PAS, replaced by E1ADDN-3304C with sealed ends from 1590283. Trycicle tractors used E1ADDN-3304C till 1590283, replaced by E1ADDN-3304D with sealed ends. E1ADKN-3132 was used on all axles, E1ADKN-3133 was replaced from 1359264 with E1ADKN-3133B when the old clamp bolt E27N-3545 with castellated nut 33983-S2 was replaced with a self locking nut 34449-ES2A, the bolt becoming a hex head type 20557-ES2. E1ADKN-3133C was used for PAS.
