I have a neighbor that has a large tractor. Its yellow not orange unfortunately lol. He's not real mechanically inclined.

The poor thing has not been greased since sand was rocks.

Me being a maintenance minded guy decided to grease his tractor for him.


I can't get several spots to take grease. It's not the zerks that are plugged. It's farther down.

I have that tool you smack but that doesn't work.

How can I get it to take grease? I dont have the facilities, time or know how to take it apart.

Thx

If you're talking about a pin or boss, you can remove the zerk and try cleaning it first. If that doesn't work, I've used a needle blow gun to remove the packed in/dried up grease after removing the zerk.

That didn't work either. I believe its a small passage like 1/8 inch and a couple inches long that's full of hardened grease.

can you push a semi ridged wire down the grease channel (hook some out) then hit it with some wd40 or similar to loosen it up?

is it in a location that can take some heat from say a heat gun.

gotta get it soft so you cn start moving it.

Might remove the zerk and run a drill bit down the passage if it's straight.

After cleaning the zerk and prior to reinstalling, fill the opening with a good penetrant, pump the fitting and get as much pressure as possible then work the equipment. Your neighbor is lucky to have you as a friend.

Mineral spirits seems to do a good job of dissolving hardened/old grease.

I would try to ‘inject” some “spirits” into those holes (possibly a syringe) and use compressed air to blow them out.

Unfortunately, there is a chance that they will not take grease again until they are taken apart.

(Regarding the syringe, they sell “industrial syringes” on the Big A…….if you go to your local pharmacy and ask to buy one, they will “sound the alarm”, and treat you like a “dope head”….ask me how I know;)(y))

In my area Tractor Supply sells both syringes and needles - everything from 1ml up to 60ml, with needles from 20ga up to 14ga. No hassle, they're out in the open on shelves in the 'vet supplies' area.

Heat has done the trick for me before, but be careful not to have a fire.

Also, what brand makes a Yellow tractor?

Ah, just go down to your nearest auto parts store, and buy a box of a selection of new zerks. For all the time you waste fiddling with plugged zerks, you'll be way ahead. Plus, the bright new zerks help you visualize them for next time!

A caution with Kubotas - I have encountered zerks with a proprietary thread (GRRR!) Not SAE, not metric. Cost like, $6 EACH at the Kubota dealership!

So, take your old zerks with you when you go shopping to compare to the new ones.

I almost bought a new hose for my grease gun, thinking that the end was worn out because it wouldn't grip the zerks like it used to. Then, I discovered that you can twist the end to loosen/tighten it on the zerk! DOH!!!
