I just acquired another Stevens tool for the collection. It was on E-Bay and I did not know for sure what it was. I just knew it had the early Stevens logo and I did not have it. Someone else wanted it as I had to give more than I really wanted to. I had a suspicion what it was used for, but after it was delivered, and I could see it better than the auction photos showed, then I knew what it was for. Ill just post 3 pics of the tool to see if anyone can figure it out. Then I'll post a couple pics of it in use. I have four different Stevens catalogs and it was not listed in them. It is part no. T-137

For size comparison the sliding handle is 5 inches long

purely WAG: pipe expansion/flare tool

whatever it is, if you have it, I want it

Frame riveting dolly.

Scott and Pep. Not it.... It is similar to the frame rivet dolly but not big enough or strong enough for riveting. The e-bay auction called it a pipe flair tool. It has nothing to do with pipe. I will give a clue. It is not really a useable tool for us today with the product that is being currently sold. . There was a thread awhile back about what it was used on. I also forgot to mention that the sliding handle is 5 inches long for size comparison.

To split cam bearings.

Holy Cow!

I don't need convincing

no doubt now...I gotta have one!

Dan, You are correct. It is a cam bearing splitting tool. Not very useable today, as the bearings are pre-split for us. But, I did not have it, and what is a "Stevens tool junkie" to do when it showed up for sale and I did not have one. So, I just blindly bid till the other guy gave up.

I got a bunch of NOS cam bearings that are unspoiled.

Dan, I also have a few NOS cam bearings I got with a large lot of NOS parts, from an old dealership in Eldorado Arkansas. I just never could bring myself to use them. I find it strange that this tool is not listed in any of my Stevens catalogs.

Wow! Awesome tool. Never seen mention of one. Thanks for sharing.

You were too quick for me Dan. That tool is probably way more gentle than a cold chisel, and the load far more controllable.

How's about "spec"ing that out for us Donnie - I might have to build one !!!

Ditto. I will be building one soon.
This tool is a more gental way to separate nos bearings than a chisel.

KR Wilson also advocated reaming new camshaft bearings and sold a special holding fixture and reamer for doing this. The reamers are usually marked W7.

Give me a little time to spec it out. Then I'll post it

I thank you kindly, my Friend !

Another tool I didnt know I needed.

Based on the pictures I built one. Took about 3 hours. Have not gone fancy to duplicate the T screw & engrave to match.(yet?) I used a 7/16 nf bolt for function screw.

My first thought was to take a chunk of axle shaft & split it in half. Getting a good, even split would be tough with a hacksaw, so I was pleased to find a chunk of 1"x1/2" cold roll in my scrap pile. 2 pieces cut 3 1/4" long. The key was to wire weld the 2 pieces together on each end on the butt line.
Set up in a 4 jaw chuck & center drilled one end. Piece was pulled out to hold 1/2" in the chuck & supported on a ball bearing center.
Turned the body (inside cam area) to .745"
Drilled 3/16 " hole for the pivot rivet & countersunk both sides. Made a double end tubular rivet.
Drilled the hole for a 7/16-20 thread in one head half.
Milled the 2 ends to square & release the weld hold.
Threaded the top half.
Counter-bored the lower half 7/16, 1/4 " deep. Keeps the 2 pieces aligned the way the original tool intends.
De-burred everything.

Wallah, functional bearing splitter.

John. Sounds like you did a good job. I also figured welding two square or rectangle pieces together would be the easiest way to fab it. Sorry about taking so long to get the specs done. I have the drawing done and most of the measurements on it. But it seems like everything on the farm needed fixed this week. I should have the specs. done in the next day or so, and I'll post them then. I have not forgot about it.

Here are the specs for the cam bearing splitter. I had to use my camera because my scanner was hit by lightening The first pic shows up pretty good, but I made three close ups just in case it was hard for someone to read the first photo. The double head rivet is a loose sloppy fit so the 2 halves of the tool can spread open on the square end aprox 0.090 as the bearing is split. I did not want to take the rivet out, so I could not measure the rivet shank hole for size, so fit it to whatever rivet or bolt you are using.

Thanks Donnie !!! Were you an engineer in a previous life ?

Steve. Not an engineer, but I have stayed at a Holiday Inn Express and I like to work on old cars. So I have to make a lot of stuff .

You da best Donnie !

Mr. Brown,

Thank you for posting the photos and drawings of the Stevens T-138 camshaft bearing splitter. Based on what you posted I made one for myself.
Whew, that was a lot of work!

Nicely done, Trent!

Kudos!

Trent, very nicely done. It may be a lot of work. But now you have a very seldom seen tool.

Just thought I would share this.
Saw one of my Stevens catalogs this morning and thought I would check it. SOB, there it is! It is not in any others I have. I did not see this before I posted what it is.

Dan, can you post a picture of the cover of that catalog. I did not see it in any of my catalogs. I'll have to look again. What page is it on. Thanks for posting ..

Here it is
