Bad grease fittings.

showcrop · Apr 30, 2012

Working on getting the hay equipment ready. The old 640 JD rake had given me cause to inspect the gear box and sure enough it had a bad bearing. At another point there was a grease fitting that didn't want to take grease last year. I removed it, sprayed penetrating oil in, worked it a few times, more oil, then a new fitting. It took a little grease, so I worked it and greased it, and ended up getting the joint greased. Pulled out a wagon that needed deck work. I was greasing the front end and the main pivot wouldn't take grease. I had to fight with it some to get the old one out but I finally beat it using the same process. It felt good to beat to stubborn grease fittings in the same weekend.

Yes it gives one a sence of accomplishment to get things repaired. Plugged fitting are usually caused by the quality of grease you use. Some gets real hard when setting even a small amount of time. The cheaper clay based grease is the worse at this.

I always use lithium. It used to be red but the last time it looked just like Never Seize. I've never heard of clay based grease. I wouldn't think that it could lubricate very well.

clay based is a death sentence. clay is just sand,
only a whole lot finer in texture.

I had a stubborn grease nipple like that. Some kind soul on here [sorry I don"t remember your name] told me to apply a little heat, which I did. That free..d it.
So should try that idea first before getting serious.

I'm curious how to remove the ones on the front wheel hubs of the Ford tractors. They are round at the base and therefore a wrench won't work. Don't want to try vise grips for fear of snapping them off.

I don't know if this is your situation, but grease fittings used to in some cases be driven into a hole kind of like a huck rivet. In which case you can drill and tap the hole for a standard fitting, but you should also remove and clean the hub so that you don't get steel in the bearings, I wouldn't worry about that on an old tractor wheel bearing because the bearings won't be working that hard and replacements are cheap. It looks like it is possible that it is a smaller hex on it like one that I removed from a wagon with vise grips Sunday.
