Taylor-Dunn wheel gear assembly grease plug size?

Radius

My 1973 Taylor-Dunn 361.

When I was removing/replacing the steering worm assembly, I lost one of the two grease plugs. Took the other one to match the threads for the replacement, and now have managed to loose it as well. Beyond frustrating, and no one to blame but myself.

I do not find in the manuals I have that it details/specifies that part, so am shooting in the dark so far as figuring the size/tpi for the replacement. Nearest I've come is a 3/4", 16 tpi (UNF), which binds about a turn and a half in.

Anyone know what the specs on these little demons are?

Thanks,

Ray~

I should say that the manuals I have list a 3/16" drive type grease fitting, but the holes are tapped, and the plugs (no opening/fitting) correspondingly threaded.

3/16" is not nearly big enough for the holes, which measures 3/4", were it even for a drive type fitting.

got the old one? if so head in to the local blue and yellow auto store...they can hook u=you up. if its tapped, the new zerk will be pipe threaded meaning it will be a tappered cut, skinnier at the bottom, fatter at the nut end. you can thread a threaded fitting into a drive in hole.

CK,

No, as I said I misplaced both, so my measurements are best guess, or closest I've come.

I will try another local auto parts store, as the first I tried seemed not even to know what a grease/zerg fitting was. Beyond frustrating when you get told by "professionals" that what you know to exist "doesn't"

Thanks.

Are you talking about on the steering gear assembly itself?? If you can post a pic of the assembly and where they screw in I can rob them off of a unit I have here (if it's the same)

By the looks of the one's I've seen...they look like an old Ford steering gear box.

Ohio,

The image is looking from under the front, driver's side wheel, with the steering column going off the image to the right.

The highlighted area shows the two holes I need pluged, with a zerg fitting in between.

Thanks,

The Taylor Dunn gear boxes I have are different than yours.

I'll tell you what I think you got going on here...those are not grease plugs. I'm thinking that's a Ford gear box that was originally built to accomodate power steering. The two power steering lines went there. When Taylor Dunn purchased them they didn't use the power assist as it wasn't needed.

If I'm right that should make your inlets some type of line fitting. I usually go to Fastenal for stuff like that..don't know if you got one near you.

Try a pipe fitting maybe?

DOOmsman,

Yes, though typically had fittings do not fit.

I finally have found a small bolt that fits the threads, but it is coming against something when I put it in, preventing its advancement. The original plugs were hollow, essentially being a small, threaded reservoir, but the lack of material in the center might be necessary. I need do some further exploring to see if that in fact affects the mechanism.

Thanks for the suggestion.

I still say it's a line fitting, which in fact may be pipe thread. You could also try brake line fittings...get a piece of brake line with the ends that are about the size of your opening and see if they work. If they do it would be pretty simple to fab something off of that.
