O.K. so this will show my ignorance but how do you grease the fittings on the Model T. Do I just fill the cap and body of the fitting and screw the cab back on? Thanks.
As you screw the cap/cup down, it forces grease into the joint you're trying to lube.
You may have to do it more than once to shove in enough grease.
You can also replace them with a Zerk fitting, not original or as picturesque but easier to use.
Not dumb at all Donald. You figured it out yourself!
As Ted says, some folks have modified their T's with the modern fitting.
Your T, Your choice.
If you feel numb
Thanks everyone. Will leave as original.
I've been really pleased with the ones pictured above--look old, but, work well--especially after rebuilding something to get it's "initial" fill of grease without having to fill the cup repeatedly.
Undoubtedly, the hidden Zerk fittings work better than the original style grease cups, but there's really no reason to spend a bunch of money on compromising the car's originality when you can get one of these handy-dandy grease-gun accessories from your local Pep-Boys store for about five bucks.
The nozzle snaps onto the grease gun and it's slim enough to be inserted into the center of the car's grease cups. And you just inject the grease. It's faster, easier and less messy, and anytime you get the urge to demonstrate the old-fashioned way, you can always take out a tub of grease and the left-over wooden stick from your last Good-Humor bar and have at it.
