Greasing

Large trucks and equipment very often you would need to lift up and let down all four corners to get pins and shafts to take grease.

"all weight should be taken off front end when greasing the king pins!"

I never knew this. Very informative thread here....
 
It takes 20 seconds to jack it up ! or maybe 1/2 hour to find a jack LOL or grease a
class 8 truck which will be an education for the use of a jack..
 
The usual problem when kingpins won't take grease is that at sometime the bushings were replaced and they were not drilled for access for the grease, or the holes were too small. The holes are carefully drilled through the grease filling holes after the bushings are in place.
 
This sounds like the new "what type of oil should I run in my flathead?" thread! Interesting reasoning from both side of the aisle.

Hmmmm, I don't see anyone explaining why leaving the chassis "loaded" is of any advantage. After reading this thread, I will be doing my grease jobs "unloaded".
 
tubman,

In my avitar picture of me with one of my model a's, notice she is jacked up for a front end grease job. Just being a whippersnapper!!!
 
'We recently fitted new king pin bearing to a 39 because they were ceased up ,after reading this thread I went out and checked a set of early king pins (rod brake type ) I noticed a slot in them to feed grease up into the bearing but its on the side not in line with the zerk/nipple so its not going to work ? it would take lots of pumping to get any grease up there ,
 
Ted, Check the bush; it should have an elliptical groove in it running from the grease hole, to enable grease to both lubricate the entire circumference of pin, and also intersect with your afore mentioned groove in pin, to grease the thrust bearing.
 
Well - I happen to have a 2-post hydraulic lift . . . and I'm way too lazy to lay on the ground and grease anything . . . so I always put my cars up on the lift. This gives me a chance to see where the grease is going, makes it easy to wipe off the excess and also to inspect everything on the chassis.

Now that I'm 60, the thought of ever laying on a "creeper" again - makes me ill. :)

Brian, I have never removed an authentic bushing on either a '39 or a '40 that had a groove in it.
I'm not suggesting it didn't happen in the rest of the world, but with dozens done, I've never witnessed a single one.
