I wish I could find it for $2.50 a tube.
Good stuff I'll have to admit. I had experience with it beginning back in 74 on forage harvestors. We took the stalk cutter assembly apart and drilled and tapped for grease fittings. replaced the seals so they wouldn't blow when we pumped grease in. Pumped corn head grease in them 4 times a day, and never lost another cutter assembly after that. If you saw how fast that knife on them rotated back and forth it would make a believer out of you the grease was some pretty good stuff. Sorry to get off Model A steering boxes.
Now my early 29 steering box a 7 tooth has original fittings on it and I've seen others the same way. What did they have on them originally? The original fittings don't have balls and springs on them to keep the grease from squirting back out. But there should be a vent on the top? Yes...no?
