Topic: How I learned the Power of a grease gun..

[754]

 A long time ago , I was a logger..
 One day somebody says the tracks need adjusting on the TD 15... Bulldozer.
So I said what do they use to do that ? Guy says grease gun.. I go FO, youre BSing me...
 But he says no really.
 Soon after that, the boss pulled a cover off the side, hooked up the greasegun..
 Started pumping away and lo and behold..the track picked up and slowly tightened up.
Amazing...
 I had never thought it through, and realized how much that amount of force on the handle , moving a small piston produces so much psi.!
 That is why we use it on stuff like brake calipers and MC,s.

First time I used a grease gun to pop a seized calliper piston was like an epiphany- like, why the fcuk haven't I done that before? Cleaning up afterwards really isn't that bad, you're going to clean it up anyway. Might as well go straight to the method you know is going to work rather than pissball about and end up using the grease anyway. JMO.

That is so funny Frank!  I was a logger after high school myself.  I operated a wood processor.  I have used a grease gun to unstick engines too.  Find the two pistons at TDC and fill with grease.  One was really bad though, and the rust fell down in between the piston and the cylinder wall.  If I had to do it again I would remove the head and sand the rust off the cylinder wall and blow out with compressed air, reassemble and grease.

I do what I can to avoid paying $100 for rod bolts, but after taking one crank apart that got the grease the rod bearing was badly scored. 

As you guys are saying tremendous pressure.

Used the grease gun method 2 days ago on my front caliper.  It was on the bench and unbolted, so just put a plug bolt in the feed line hole and used the bleed nipple.  Grease gun fitting popped right over the top.  Clean up not too bad,  Looks like pipe cleaners, brake cleaner, acetone and air. First time that piston has been out since installed in 1972. (yep, they were a little spongy.)

In 81 we worked on the Revelstoke Hydro Dam project..
 That was pretty cool.. Along the Columbia River, falling trees and clearing. Some big wood.
Sometimes we would go to work by riverboat, no roads.. Drop two fallers off, gear and a radio.. Pick you up 9 or 10 hrs later.. Spent the summer in Mica townsite, we had 3 big camps in 3 long rows.

 Made a lot of cash that fall , best job I ever had...  Its all underwater now...

Used the grease gun on a junkyard twin piston caliper two weeks ago.

I've never understood how the pressure is contained. It seems to me like it should just squirt right out around the end of the grease gun but it works and it's not as scary as compressed air.

That's the beauty of the grease, I think. How much safer it is. More of a "bwah" when it goes, instead of a kaboom.

Airborne brake fluid can be nasty on nearby paint..
Generally with the adaptor, it takes under three minutes. And about that long to get most of the grease out. If its really wet in there, the grease often comes out in one lump.

A particular nasty trick some guys would do in some shops is put a big blob of grease in someones coverall pockets. Never goes over well.

I once came in to work and found a thin line of grease on the back of every tool on my bench. Good times.
