in cleaning the grease cups on my 21 t the large cup on the rear of the hogs head In scraping old crease I found a broken wire like a snap ring that was holding what looks to be a needle valve,is this a important part that needs replaceing or will the cup work without it. my t wont be makeing long trips just enjoyable 2-3 hr through tho country ON DIRT ROADS.
There should not be anything in there, the cap just screws down to force the lube. Somebody tried to clean the hole when the grease got hard and lost their "tools". Remove the cap and clean it all out and refill and you are good to go.
Richard ,mine has the same thing inside. It was not loose so I figured it was suposed to be there.
I have found several of these grease cups but have no idea what the needle was for.
Does it look like this?
Eric thats what mine looks like.
Hey Jim ,I sent you a PM.
I found one like that on my 18's uni-joint cup too.
It's to keep the cup from turning on its own due to vibration etc, yes?
That style of grease cup is aftermarket, Ford did not use them. They do have the advantage mentioned by Duey C above in that they are less likely to turn on their own.
Richard that is good news for you and I. I live on a dirt toad and you plan on driving them as well. Lots of vibration!
Drive safe and often
Empress brand dope cups.
These are made to prevent the cap from falling away, the supplier provided these to Ford, so you could say Ford did use them!
Lots of dealers sold these.
AHA. THAT MAKES SENSE THE PIN IN MINE WAS DOWN IN THE OUTLET AND I COULD NOT FIGURE OUT HOW THE GREASE COULD GET THROUGH.SO ITS MY DUTY EACH TIME I SHUT THE GAS OFF TO TAKE A PEAK AT THAT LITTLE GUY.THANK YOU ALL.AND HAPPY SAFE MOTORING TO ALL OF YOU.
Don't throw the grease away!
Put it on your hair so you can look like the Fonz.
The point on the cap is only there to keep the cap from vibrating off. Every Model T I've ever owned has had one.
Our 14 has one with a needle in the center and i think it is on the steering lower unit.Whenever i grease i fill all cups and turn them all the way on tight? The exception is the fan cup which is used sparingly? Bud.
Bud, or anyone that may not have seen, I had saved these drawings awhile ago.
I love these drawings yet the one is more vague.
Funny, both of these don't mention the cups on the Hyatt outer bearings on the rear axle...
