Steering Box Adjustment

[KM Thompson]

Hi, everyone.
I have a 1960 530 with mechanical steering (the casting number on the steering box is G1055). The steering has considerable play (about 120 degrees at the steering wheel).
Is there any adjustment on the steering box?

Yes some just take adjustment screw on the steering sector in front of the radiator, if that does not take it all up, you can remove the cover rotate the steering pins the steering arm and or worm moves,, I know at lest one parts supplier has new pins for them also, normally just turning them to a new wear area solves it I like to fill the sector with corn head grease if the main seal leaks oil

Here are a few pictures of what Case Nutty was referring to if the adjustment doesn't do much. The steering lever has three pins pressed into it that ride against the worm gear. Over time they wear, and actually get flat spots as the pictures show.

The early 530 should have a similar adjustment screw on the bottom of the bolster to set the lash between the steering lever studs and the cam (worm) gear. Before you lift the cover to check the studs, back off the adjustment screw, this is important because when you replace/turn the studs the lash decreases and bolting the cover back down may break the steering lever the studs are press in. The steering lever slides on the lash adjustment plug. Be sure and lift the cover and do as CNT & Tg wrote as worn/cratered studs can break the steering lever also if lash is adjusted too tight w/o checking studs. When done with replace/turning the studs and cover is back on adjust the steering wheel slop per this instruction page. Factory lube was SAE 140 gear oil, corn head grease per CNT is my choice also.

ops I messed that up Thanks for the correction Joe,, too many repairs in my head files, I was thinking the screw was on top,,

CNT, you have addressed and/or provided repair guidance in an amazing number of different machines and models over the years. We all have a little fog in the memory now and than.

Thanks, everyone. This is starting to look more like a winter project than I was hoping for. Oh well.
