What are these called ?

What is the correct Name for these clinch stud washers ?

Looked under Reverse Floodgate for a duck ***, no luck.

 

The one on the left is a thumb, the other two are fingers.

 

Looks more like a bushing than a washer to me, if that helps at all...

 

Ford nomenclature for use in the truck hubs seems to be "tapered dowels"; they are indeed hollow dowels to locate the hub that is clamped down by the fasteners.
I wouldn't be surprised if they still exist in a similar modern application...have a Ford dealer look at basic part # 1142 and see if there is anything like it in the catalog.
I think a lot of trucks use similar locaters and likely the part crosses over to lots of things besides Divco and Ford, so next stop would be a truck repair place.

 

IIRC toyota uses them in some of their 4x4 front hubs, I think it was a early '90s 4runner that I worked on that had em. Might be worth a shoot if you can't find anything else

 

Dorman or any big truck parts house. Used under nuts to center axle flange on hub.NAPA or Car Quest should have.

 

Used to have an Snap-on "axle stud cone" pliers; but I usually called them a pain in the a**!

 

Still used today on medium to large stuff. A good thwack with a hammer on the axle edge and most pop right up.

 

ARP calls them 'insert washers', what they do is create a shoulder for a nut to tighten against so that the fastened piece won't collapse into the hole. A typical use is aluminum cylinder heads etc where you are fastening against a soft surface and want to keep the hole from collapsing into itself.

 

These aren't the stepped kind like the "insert washers"...the slightly stepped appearance is a digital artifact in the picture. These are conical and serve as locaters, effectively turning the stud location into a doweled role to locate the axle end properly on the floating hub.

 

Good example of what FNG stands for.

 

Bruce is right... they are axle dowels. And really should not need to be replaced unless you are missing some. They are sized for the stud they go with. for example all 1/2 ID ones are the same no matter whose axle it is.

If you don't have the Snap-on pliers that opens up the split, you can do it with a little screwdriver.

First you need to pop them loose by beating the end of the axle, one time usually, with a large hammer. after removing all the nuts and washers. Most have star washers under the nuts and lock washers on studs without dowels.

 

There called wedges .... A lot of your Heavy duty trucks use the them to center the axles on the studs

 

Try Eaton axles & rear ends

 

The Ford shop manual calls it a dowel, but no part #.

This is from the '74 model year, Rockwell single speed rear axle section.

 

Axle stud dowel,used even on heavier trucks today as axle locator on studs,normally have the star washer between them and nut so they don"t spin when tightening nuts. As said earlier good wack on center of axle will break them loose ,just have your grease pan ready to catch gearoil. Mess with these dang things every brake job on heavy trucks. Get you a pair of the pliers,makes life easier.Learned real quick to wear the saftey gl***es sometimes they split and come out in 2 pieces.

 

Smart ***.......

 

Drive flange wedges. See page 140 of the Dorman catalog section I've linked to below. You can get Dorman at most auto parts stores...
