East of Broken Bow | Does the bushing have one hole through it for grease, or two?
Often, bushings have 2 holes opposite of each other. That way if there is a load on the bushing that would make it hard for grease to go through the hole, it follows the groove around to the other side and greases the side of the pin where there is not load. We have a tractor where the front axle pivot pin bushing originally had 2 holes in it, with the groove. The new bushing had the same groove, but only one hole. Thinking we wanted the grease to flow to the bottom of the pin, where the weight was, we put the new bushing with the hole pointing down. Turned out to be a mistake. Now, when we grease the front end on that tractor, we either have to have tha axle a bit crooked (park one wheel in a hole or on a ramp or something) or lighten the load on the front axle in some way. Either with a jack, or if there is something on the 3-pt, if we raise it, often we can get it to take grease. Sitting there with the full weight of the tractor on the front end, a cordless grease gun will not push grease into it. Get one front wheel a foot or so higher than the other, and I can grease it with a pistol grip gun.
Maybe will never be an issue for you, but something to consider. | |
