HD 16 cable dozer
Question. bottom track wheels have no grease zerts or plugs
only way I can see how to lubricate is to work a grease needle into bearings 
Any other suggestions?

No grease zerks or plugs?
 Some had button zerks like this,

Some used a plug at the end of shaft and put a tube in that screwed inside the shaft and pumped oil in until it flowed clean around the tube...


and others were just simply lifetime sealed rollers and when they went dry, their life was basically used up and you replaced them, or rebuilt them.

Some also used a square drive plug, the plug was located on the wear surface of the roller, smart, huh?Wink

When did AC go from 1000 hour greasing of rolles to sealed for life rollers.



And sealed for life Cat rollers will live a second life time if you add cornhead or other lite grease as soon as you see a leak. The one I did not grease last 2 or 3 days before it was junk.

When I dismantled the junk roller the shafts had no grease channels drilled in them
Therefore they must have been lifetime sealed.
I think I have a method to grease these lifetime sealed rollers 
I will post if I am successful

I took a plug from a junk Cat roller drilled for a grease fitting and pumped it full.

That's what I did 
First picture shows the space between the bearing races of a dismantled roller

I will try to post sequential pictures
first picture shows area between bearing races on a dismantled roller 
second picture shows where I drilled hole for grease fitting this can be done with roller still on machine 
I drilled and tapped for a grease fitting on a non contact portion of the roller
Used pneumatic grease gun 1 and 1/2 tubes of grease 
Removed grease fitting 
Sealed with socket type pipe plug
