Zerks and tears

[VroomVroom]

Yes they make greasing go faster.

They don't fit every fitting due to the diameter and length but they fit the vast majority of grease fittings.

I might have had to replace a zerk fitting that would not accept grease once. It's rare. Sometimes on tractors the force on the part can keep grease from flowing. You can move parts around to get the weight off and let the grease flow.

Yeah like Quebecguy stated he had to lift the front wheels off the ground to grease the pivot point on front axle. I tried that too. Might try again though and really pivot the axle. I barely had the wheels off the floor

I have been using one for many years now. They make greasing fun.

Now that's a funny definition of fun!

Not mine, especially when my wife finds that my greasy shirt has stained the laundry load of clothes.

If I have a zerk that won't take grease, I use a steel wire brush that painters use on the face of the zerk. Frees it up and you are god to go.

I almost bought one then realized, zerks are pretty cheap.

I’ll have to look at the grease us used today. It’s white motor master grease. I got most of them after hours long battle. But still have the universals go do. How much grease you put in those? I lose so much around zerk it’s hard to know if any is getting in. I was awful tempted to buy electric grease gun today. See how greasing goes next time first.

brother-in-law bought a dewalt battery power grease gun for his dozer. on a couple the pressure relief on grease gun activated and grease came out of it, in other words didnt neccess work. Still had to replace part of them.

I bought one of those about 20 years ago, I've probably tried it a dozen times and when I'm done I still have a plugged fitting but now I have a big mess too. They sure look good in the advertisement video.

Yeah it wasn’t so much about getting in easier with the electric. But more to do with it’s easier to fiddle with grease gun tip while pressing a button than wrestling with a pump handle in awkward spots. But I think I have all but one on the tractor giving me an issue now so I’ll keep with the manual. Might need to warm this one up. Pivot point on front axle , I removed the nipple but still can’t get any in. Not sure if I missed that one or what but the tractor I greased pretty often do grease squeeze out of that no issue. But can’t get it in that one at the moment. None leaks out either from zerk/ gun

I bought the Dewalt (20v) greaser. Put a zerk clamp-on connector on the hose. It clears "most" of my Zerks and gets grease in.... not all however. But, the manual guns were giving me fits especially when I was standing on the tires, doing the front-end loader zerks.

I thought I had a bunch of stuck zerks but turns out my lever style gun stopped pressing grease. For the life of me I can’t seem to figure out what’s wrong with it. They’re cheap enough that I’ll just buy a new one, but the frugal mechanic in me makes me reluctant to throw away something that likely can be salvaged.

I work on a lot of older forestry equipment and bucket trucks. It is common place to find a few neglected grease fittings. I've tried the hammer type grease busters
and the lock on grease tips. What I've found that works for me is to use a good quality hose on the end of your gun with a working pressure of 6-8000Lbs or more.
When I run into a fitting that won't take grease, even when holding it on the zerk, I take the zerk off and put on a new one. If that doesn't work I take off the hose
on the end of the gun and put on a hose that i blew out most all of the grease and fill it up with PB Blaster. I put the hose back on the gun and squirt it in. It may
take 2 or 3 shots of this to loosen up the old grease. I then move whatever the fitting is trying to grease up and down or rotate a few time in both directions and
then grease it. Had best luck doing it this way. The worst one I ever had, I had to heat up the joint and put the PB Blaster to it 3 or 4 times before it would take
grease, but it did. Like I say, this works for me.
