$40 dollar grease gun from amazon, put new grease in it

Put air to it, it wont pump out grease

I havent greased the machine in about 3 months or longer

Can someone tell me maybe why it will not pump out the grease?

2nd problem: here are pictures of the front pin missing, almost every hour I need to put new nail in there

Anyone recommend a pin set I can get off amazon that would fit this and others down the line with kubota tractors

The pin is actually missing on the other side, but the bigger sliding piece somehow is not sliding out

This sliding piece will slide out if no nail/pin there

here is a set for $20, maybe one of those will fit that spot?

These appear more like the original one that used to be there

Joe:
A nail is not a suitable "pin" for THAT application.
You need to put a proper diameter BOLT (with nut) in that spot!

Yes,

I will look through the hardware and make something work

in the meantime, I will wait to see the responses about ordering a kit filled with pins of all sizes that is budget friendly (instead of 1 pin from messick for $30 delivered)

Also with the grease gun:

If i unscrew the grease hose, it still does NOT push out grease

I know its probably something I forgot to do, someone knows

all guns have a 'purge' plug.you unscrew it,pump a few times, when grease comes out, tighten the plug, good to go....

ok yes I just got off the machine and will try to find the purge

update on the grease gun:

Went to a bigger compressor, still did not push out grease

Then, i noticed the bottom clip (you can see in the picture) went missing

Looked around, cannot find it

then decided to take off the grease to see if its even pressurized, big mistake

All the grease come out

I'm understanding - there is pressure in the grease chamber area, but it is not making it to the nozzle

There is a hole on the other side of what the picture is showing, on the grease on, there is a hole that pushes out air, tons of it

Sometimes, I will hear the cylinder pushing the grease forward, but most of the time,

all the air is escaping from that hole, and no grease is pushing forward

maybe that silver button near the base of the black cone ??
if all else fails, maybe read(well look at) the manual that came with the gun ??
one thing for sure, confirm the air pressure at the gun !!!

I tried pressing that button, it did not make any difference

Make a call to the manufacturer in China and ask for instructions on how to remedy the problem.

 

[joesmith123]

this is the second grease gun I broke/mig

one thing for sure, confirm the air pressure at the gun !!!

dont I know that there is pressure in the gun since it pushed out all the grease when i unscrewed the grease holder?

Yes I might have to do that, i doubt they can help, maybe it is broken, it was the cheapest one available on amazon for $40

 

[hagrid]

The grease escaped because it looks like that gun has a spring loaded follower... that you did not disengage

I have a Lincoln (brand) pneumatic grease gun,..... it sits on the shelf.
Tried it ONCE.
PITA dragging an air hose around.
Bought a DeWalt 18V battery powered gun.
LOVE it!

 

[GreensvilleJay]

Had one of those 'garage style' units on wheels, 30gal grease, 1/2 full....used it 2-3 times..PITA draggin air hose..got rid of it fro price of 3 new hand style units.

 

[GeoHorn]

My old-reliables…no hoses, batteries, or troubles:
(5 of ‘em, each with a different type grease for different services:

The air pressure had nothing to do with all that grease glooping out. You didn’t pull the rod with spring loaded follower before unscrewing the cartridge.

I dunno....
From his picture, it does seem as though the follower rod actually may be pulled back.
Kinda hard to know for sure!
