Grease fitting not taking grease

Glad to see someone found that tool useful. I did not have good results with ag equipment or loader pins. Maybe fill it up with gas or cyclohexilene. Then give to the young man that was removing all the truck decals with a heat gun. Caught him on the one that says " Caution! Keep away from heat and open flame!" You know the one one the fuel tank.
I have personaly had better luck with a clean hole, new fitting, and heat the spring - cylinder end- etc if it won't hurt anything. Nowhere close to red only maybe 200-400 degrees. Then grease them and spank them with a hammer if needed, use PPD'S. Then grease them often for awhile. If that does not work or you do not want to burn some paint off take it apart. May help to get any pressure off of it first.

 

This is a dead horse; but lets continue to hammer away on it.
Here's what I got.

Point taken - this is a nifty little device. I am a tool and gadget collector and this appeals to me, but........

Please review my previous posts on this subject.
I would not hesitate to say that in 44 years as a Tool and Die Maker in 14 places in Northeastern Pa. Industry,
and driving Trucks for myself since 1983, I have encountered many more clogged grease fittings than the average guy.
A) - They make a little rubber cap that snaps on them to keep them clean. They work, never saw a bad one with a cap. Get them.
B) - screwing out the fitting and cleaning it out by hand with small drill, then snapping on the grease gun and pumping - clears most fittings.
C) - the tapped hole fitting threads into; run a smaller drill in (by hand) also, to core out sludge if its old and crusty in body of item being greased.
D) - they're cheap - if they're hosed up, throw them out!
E) - I'm cheap. Why spend 20-30 dollars on a tool to fix a "2 for a dollar" item? (I could copy this for 3 bucks worth of metal stock on a lathe.)

Last place I worked was 18 years in the color offset printing industry. (Like the way newspapers are printed, only color, and glossy stock.)
They had thousands of fittings on each of the six presses, and thousands more in bindery on 8 or 9 bookbinding and trimming machines.
We had 4 - 12 hour shifts, for 24 hour coverage. So you worked 3 12's - and off 4 days. Sit around 4 days? not me.
Mon,Tue. Wed. - A Shift ~~~~~~~~~~~~~~~~~~~ Thurs Fri.Sat - B Shift
Mon Tue. Wed. Nights - C Shift ~~~~~~~~~~~~~Thurs. Fri. Sat Nights - D Shift

The union negotiated Saturday as a strait time day for the company, If we got the 4 hours to make a 40 hour week thrown in. Sweet deal.
The pencil pushers crunched the numbers and agreed. So in 1983 - with 4 days off every week - I bought my first of 7 trucks.

 

This post went from grease fitting check balls to things that won't take grease somewhere in the middle.
Mr rolls canardly is 100% correct but I thought I would share what I learned this week. It is about things that will not take grease not the fittings.
An industrial plant I have been working it does this. Removes the grease fitting and connects a porta power hose. After it is opened up they install a fitting and grease it. If the bushing has turned in the housing drill a hole through it and repeat the process. No it is not a truck but just thought the information might help someone sometime.

 

They make a grease impact. You fill with grease, place over zerk, and hit it with hammer. Forces grease in.

 

You're kidding, right?

 

No works pretty well.

 

Lincon part number 5808. I think.

 

I think you missed my point, 1/2 of this thread are posts about that very thing. I thought you were kidding because it has already been discussed quite thoroughly. The Lincoln # is 5805.

 

I purchased that kit a few years back and decided to replace all the fittings in the driveline before i greased them, every new zerk didn't reset with grease coming back out of them.
after examining the new ones that failed i noticed the ball bearing rolled to the side, i threw the kit in the garbage.
