Backhoe Best way to get grease in a stuck fitting.

[CMV]

No idea how old yours is, but the old JD BH I had needed about 14 zillion zerks hit (exaggerating - prob only 13 zillion). So whenever I had any that were difficult, I swapped them. Kept a set of fittings & wrench in toolbox. Was so much better to fix it once than to struggle with same fittings over & over. Any I "fixed" by just tinkering to get it to accept grease seemed like it was a problem again next time.

I just figured they must be full! HA HA

Recently I purchased a tool that you fill with grease then place over the fitting and hit with a hammer. Haven稚 got a chance to try it yet...

My machine is a 2011. The backhoe boom has been well greased and all took grease. The loader I don’t think was ever used and might not have been greased as frequently.

grease behind zerk is probably hardened up. if that is the case take zerk off and blow out with air gun.

Pull the zerk, clean the passage with brake clean and a wire then some WD, reinstall or new zerk and go,
royal pain but works the best in most cases,
also the impact type tools to my knowledge are to be filled with solvent or light oil not grease

I can handle removing the zerk. Removing the pin is a lot bigger job.

I ended up removing the pins and still haven’t got anywhere. This doesn’t have a simple hole for the grease, but it has a bushing in the cast arm. The bushing has a grease groove on both sides so there’s no direct path. I removed the grease fittings, cleaned out most of the grease, and filled the holes with Kroil oil. I’m hoping that works.

I finally got grease through both sides. One gave up after the kroil soaking. The other required another heating.

For feature reference a lot of times a deep socket can be hammered on and slid in as the pins are being slid out and removed towards the other side. The socket holds everything lined up as you clean up the pin or bushing. Then just tap everything back in as the deep socket slides out.
