Tinnerman hose clamp R & R

[duckbill]

Is there a special tool designed specifically for Tinnerman hose clamps? I can see how they can come apart and be put back on, but it looks like a special tool to engage the notches would be helpful.

I have also wondered about that. I'm sure there is someone who knows but I sure don't. A tool would sure make it easier to replace.

I've searched the internet for Tinnerman pliers, and so far nobody here has described the correct tool. I would imaging the correct tool is a type of pliers made for the job.

Well, the seal on my Buick's water pump just gave out (Oh, joy! ), so while I was at the auto parts store I checked out all of their tools in case they might have something that would work on the Tinnermans. I found a tool that works. I had to modify it slightly with a file, but it does the job. The only down side is that the tips could be wider. Oh, well.
Here is an "after" photo of the tool points. I didn't get a "before" photo, sorry to say. But, if someone gets the tool they will see what needs to be done. It is called a "C-V Joint Boot Clamp Plier".


I'm still looking for a proper tool, though, if anyone can help.

I just use a screwdriver to disengage and a pair of needlenose pliers to engage the teeth....I have two dacors and a DARAM that had dacor hoses with the tinnerman clamps......it's sorta an art after you get the hang of engaging and disengaging.....but easy to learn..........

Survivair (a manufacturer of SCBAs) mentions the following tool to tighten Tinnerman clamps:

The best tool for this operation is a pair of pliers such as Sears 9HT52136. File pliers to a rounded tip which will easily fit into the clamp notches.

Yea, I tried the needlenose pliers, but I was afraid that the points would slip off and mar the finish due to the angle. Hence, the tool quest. Small screwdriver works fine for taking them off, though.
I didn't check Sears, but thanks for that information, Joe. I'll go see what that tool looks like.

Terry;
Your custom made Tinnerman pliers are a stroke of genius! I've been looking for original Tinnerman clamp pliers for years and I've heard reference to them but I've never seen a pair. I'm attaching an ad from a June 1945 issue of Popular Mechanics. It shows the "new' Tinnerman clamps that were mostly used in military aircraft. But surprisingly, the pliers they show in the ad are just a pair of standard pliers.

Thankyou, Dan.
The clamp in your picture is the same style which is on the 1 1/2 inch hose ends of the nice Dacor R-4 which Robert ('scubadiverbob') gave me (He is a very nice and generous person. I am indebted to him for that one!). I tried pliers before like your ad shows, but I knew these clamps are a little hard to find, and one slip and, well.....one scratched Tinnerman.
The 1-inch end Tinnermans are a different design and were really the ones that had me stumped for a solution. The tool I made works O.K., but I wish the plier blades were wider where they contact the clamp.
Thankyou for sharing that. I love how the old ads were so instructional.

By the way, 'JES' Joe, thanks again for the information on the Sears tool 9HT52136, but it turned out to be a dead end. The guy at Sears here couldn't find a tool under that number. It may be that he just didn't know what he was doing though.
