unusual "Stevens" tool, guess what it is, specifications added to post

[dobro1956]

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

[Pep C Strebeck]

Frame riveting dolly.

[dobro1956]

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.

[Scott_Conger]

Holy Cow!

I don't need convincing

no doubt now...I gotta have one!

[dobro1956]

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.

[dobro1956]

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.

[Sean Butler]

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

[Allan]

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

[RajoRacer]

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.

[dobro1956]

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.

[dobro1956]

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 ?

[dobro1956]

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 .

[RajoRacer]

You da best Donnie !

[TrentB]

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!

[dobro1956]

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

[Dan Hatch]

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.

[dobro1956]

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 ..

[Dan Hatch]

Here it is
