Adding grease to steering box

On the advice of my friends on HAMB, I purchased a tube of Deere Corn Head grease to add to the steering box on my '36 Ford. Now I can't find any way to get it into the box. There is a cover on the box held on by bolts. Is there supposed to be a grease fitting somewhere? How do I get the grease into the steering box?

 

I take the fill plug and drill and tap a hole in it for zerk fitting.

 

There should be a plug on the top ofthe box between the bolted on cover and the steering shaft/mast jacket. most likely a square headed one ,but could be kex or recessed. Trust me there is a plug there !!!!

 

The adjusting screw may be more centered and uses a bigger cap. Oh my model a i just put the grease in a grease gun and held it upto the hole and filled her up.

 

Is your box leaking with the recommended 600w oil? I'd stay away from grease personally - I don't see how it would flow back into the worm & sector teeth once it has been pushed out.

 

I've always used White Lithium grease . I push it in through the top in a hole on my 53 Ford truck. I've done the same on a 78 I have too. scrubba

 

Correct lube is 140 gear oil, what I would choose here. Thick grease will quickly kill the gears...it gets pushed away and stays there. Any grease would have to be thin and pretty close to runny.
Recirculating ball boxes are designed for grease as the recirculating ball system keeps dragging it back in...on those I have had I simply drilled and tapped a bolt that held the cover on and used the grease recommended by GM pumped in that way.
My thinking is that if you can't get it in via the stock fill plug, it is too damn thick and will be a serious mistake in a plain gear box.
Stock '36 Ford has a removable plug near top of casting,,,it is tipped so it points straight up. Proper lube should trickle right in there, or you can drill and tap it for a Zerk so you can force in something too thick to function.

 

I've had good luck using synthetic grease,...and being as close to the exhaust as mine is,...the stuff stays where it belongs.

you guys should actually research corn head grease. not thick enough to make "voids" but thick enough to not leak out.
