Lubing the front U joint on my G1 Renegade has been impossible until I got a new Lincoln nozzle. It is the latest Lincoln 5803. It is different from the previous 5803 in that it has a rubber tip. The rubber tip conforms to the opening in the zerk and that forces more grease into the zerk and less grease will squirt out the edges of the nozzle. It is easier to use than a regular nozzle as long as the nozzle isn’t too long or too hard to see. With this nozzle you need a good view of the zerks ball so that you can center the nozzle.
For the A arm zerks I am getting one of these tomorrow.
No more fine tuning the coupler so that it snaps on but isn’t too hard to remove.
I attached a photo of it.
