    Heyco Strain Relief Tool

    My Leslie amp and other pieces of equipment use Heyco strain relief bushings to secure the power cord. These suckers are hard to get out and back in without the right tool. Heyco sells several sizes of pliers for the task, but it looks like I'd have to have two models (22 and 30) to cover most bushings. That's about $200 worth of tools to use ten times.

    What do you use to remove and reinstall these parts? I usually end up with a small pair of Channel Locks or a large pair of needle nose pliers. Both tend to booger up the strain relief.

    I know what you mean about the price per use and I really agonized (a long time ago) about spending the money for the specialty tool. However, my price per use & the part and finger damage avoided over the years has been worth it. I use the model 22 which is advertized to fit "all strain relief bushings for chassis ports up to 7/8". I have never needed a different size tool. It is "adjustable" in the sense that you can remove the pivot screw and move the jaw position on the gear. I have done that when I used it for very large or very small strain relief bushings. Hardly ever need to do that though. I wouldn't want to be without the tool now.

    As I understand it the model 30 is a heavy duty version of the model 22 but it fits the same range of parts. The 22 has been adequate for my use. One supplier's info with photo is at the link below .

    decent needle nose pliers and heating units in boiled water also work good

    That's what I was really curious about. The strain relief on the Leslie reverb amp is quite large - probably 9/16" or more. If the 22 will work for the large one as well, I may pull the trigger and get one. Mouser has them for $55. I should have bought them 30 years ago like I did my Keystone 1707 staking kit and my Roper Whitney No. 5 Junior punch set. Both tools have been indispensable over the years.

    I use the cheapie like Ted posted and have never had any issues.
    That being said, when someone else was footing the tool bill, it was very nice to use the "official" tool , very high quality that you can feel.

    I have had many specialized crimping tools that were really expensive but never felt the need for a strain relief tool when the long nose vise grip tool was right in the tool cabinet. It does not have the rough corrugated surfaces that the normal vise grip pliers do. I had one of the simple ones that Xilite used to have, like the one Ted showed but lost it 10-15 years ago. They work fine on smaller strain relief but need more gripping power leverage for the large ones.

    That HK tool for $5 looks like a real bargain.
    On thing I like about the purpose built tools like the 22 is that it doesn't just squeeze. It holds that strain relief so you can pull and push to remove and install.

    I'm with Stan. I don't do repairs often and I've only had to crimp maybe half a dozen of those bushings in my life. So take this with all the salt you like, but I don't, and probably won't have any unitaskers in my tool box. I have misc. special nosed pliers and I've managed. FWIW those Heyco bushing pliers look TOO burly. If you need a cam levered pinch on the bushing you're probably squeezing it too damn hard to be safe for the wire jackets! JM2C on that.

    OTOH if I crimped a bushing every day (or maybe once a week) I might buy the Heyco tool.

    Stiffer cords that are a snug fit in the bushing take a lot to kink the whole cord. The cam leveraged tool is probably the only one that works well in that case. But as you say, unless you are doing a lot of cord replacements, it may be overkill. On an assembly line it would be essential (unless that job is now robotic).

    When I have to squeeze a stiff jacketed wire into one of these, instead of fighting it, I get out the heat gun and warm the area to soften it.

    A lot of things are better if you warm them up first.

    So, who wants to go first and rate this thread "5 Stars?"

    I <guess> it's related to "strain relief" in a way...

    My wife is wondering why I'm laughing like a loon with the TV off and no one else in the room!

    Enzo put it out there, I shoved it to the edge and he steps back in and just kicks it right the F off. Five stars!.. Strain relief... Pfft... Love it.

    tedmich, if the brand name was the next island over, Assateague, you'd have a real knee-slapper!

    FWIW I happen to know both Chinc- and Ass- ateague are in Maryland, some distance from New England, they got a lot of nerve claiming New England clam chowder. (I know, it's the creamy type not the minestrone + clams type Manhattan c.c.)

    And it does work better warmed up, who wants cold chowda. Hell I even boil up my vichysoisse, don't need a free botox fix.

    "While I'm workin' my ass off, you guys are clammin' it up! You're all fired!" (Buddy Rich famous tour bus rant, for a real laugh look it up & have a listen.)

    If you see food eat it.

    If I see a Heyco strain relief, I break out the ol' water pump pliers AKA channellocks. One more tool and my rack will 'splode.

    I have a lower wattage hobbyist heat gun perfect for heat shrink tubing and the like as well as the industrial strength one from Harbor Freight. I just now ordered the next to the last one in the eBay link above, now up to $6.xx...
