Grease channel blocked

[Landrover]

One of the large pins on my plough won't take grease from one side, is there anything I can put down it to unblock it ? I'm NOT removing the pin, I've tried carb cleaner, brake cleaner and a grease nipple unblocker tool that you hit with a hammer(waste of time) anyone any suggestions that doesn't involve fire of any sort please ! Some magic chemical I could put in it ?

Take the nipple off, get some wire or a small screwdriver and get as much crud out as you can, them keep spraying anti rust spray into the hole. Eventually it will get through the rust and then bobs your uncle..

Can you jack or lift something to make the pin ever so slightly move away to make some room for grease

Or diesel, with an old fashioned oil can.

Take nipple out, wind in the appropriate size drill bit…by hand (or with use of pliers etc) & taking care not to snap it. Should pull out a lot of the crap. If you won’t tale the pin out could you rotate it a bit & then pump grease in?
Some grease guns produce more pressure than others.

Take the grease nipple out, heat a wire red hot and poke it in to melt the grease, stick the nipple back in quick and ideally using the likes of a Milwaukee grease gun (10,000psi pressure) should get in moving

I've tried the hot wire down it and it's clean, it's just at the very bottom where it goes into a hole on the side at an angle is the issue, I've had a Milwaukee grease gun screwed directly into the hole and no luck !

Sometimes works to put grease gun on get it under as much pressure as you can and then leave it under pressure for a while. Alternatively get it under pressure and work the joint that won't grease.

Pickling paste.

full hole with duck oil or similar refit grease nipple then use your grease unblocker tool also filled with duck oil.

Drill bit, diesel and a new grease nipple

Fire

If it’s on a moving pivot point have someone move plough while you push grease in if safe to do so.

Get one of these. Cracking bit of kit.

The op says he tried one and it was useless,I’ve one here and it’s worked fine, apart from the time I used a sledgehammer on it

 

[Cab-over Pete]

Oh aye, so they have.

There’s only one thing for it then…


….. bung the machine in an auction and let someone else worry about it!

Have you got a hot water pressure washer? I’m not the biggest fan of this approach but it has worked for me on some seriously blocked up grease holes. I always grease the hell out if it afterwards to try and counter having just put water into a lubrication circuit.

The heat is probably the most significant factor, so you could try gently heating the whole pin with a propane torch, then hooking the grease gun back up.

i saw a video somewhere, they used a porta power to inject hydraulic oil into the blocked line with an adaptor. might cause other issues though

If all else fails & you’ve tried everything, you could always become a dairy farmer. You wouldn’t need to grease it then

A grease gun will pump oil, diesel, parafin. Hold it upright without the plunger. Move the joint as you apply pressure.
