Auger Zerks

I've been wondering, my augers do not have zerk fittings. There are plastic disks on the shaft in between the augers though. Question: What is the purpose of those disks ? Are they supposed to keep moisture out ? If so how well do they work ? Thinking of installing zerks on my augers as a mod / upgrade.

My guess is you have multiple augers not just one piece? If yes they are the flange bushings. I believe they used plastic so they don't rust.

You can install fittings, but I think you would have to do one on every auger. You might already have fittings on the end auger bushing where the auger meets the housing, but I'm not sure.

Not sure on your machine, as I don't know what it is.

Many augers do not have enough meat (thickness) on the auger shaft to drill and tap, and then screw in a zerk fitting to properly operate. That is why on many they just press one on, or don't put any on.

Every machine, whether it has zerks or not, should be lubricated through the shear bolt hole as well as the ends. The shear pin should be pulled periodically and spun freely to make sure things are moving freely, and to inspect any shear pins.

If you put zerks on the MTD style augers, then you would have to use a whole grease cartridge to grease it, but not needed since the auger shaft sits so far away from the gearbox shaft, that it will never rust to it.

I find it easier and cheaper (plus much cleaner) to just pull all the shear pins, and lube them up with a 'Sticky' Lubricant. They're not a tite fit, and as long as they don't freeze up, you'll be fine

Thanks guys. Appreciate it. It is a MTD / Yard Machines. It does have multiple augers. Four of them. Good information. I believe that oneacer is right. Not enough meat on the shaft to install.

Plastic doesn't rust to steel so you are good..just spray around them on occasion of whatever lube you want to use.
If it still rusts ...no big deal as those plastic bushings won't rust to the shaft.
Worst case scenario...when you go to rebuild the gearbox someday you have to mangle a bushing or two...no big deal..they are cheap and plentiful.
You will have that new gear in and your machine back together while the others are still trying to get their augers off the shaft... you win.
You do want to keep the ends of the shafts lines up(where they go into the sides of bucket)
Those bushings there actually do something... It's plastic.. if the end of that shaft rusts it will eat that plastic up like sandpaper... Some spray lube... Finger and grease is the way to go there.
Some Cubs have zerks there.. when I have to replace my bushings someday I will either add zerks there or buy the cub Cadet bushing retainer with them already installed
