Can I just heat shrink this wire to save it?

Recommended Posts

Look at the used to be red wire on the left and you'll see a bunch of frayed rope looking stuff. I'm wondering if I can just snap the end off and slide a piece of heat shrink down over it and then re-terminal the end.

 

Can't see why I can't do that. Just wanted to run it by you folks....

If it were me I'd try it but find some way to keep it away from those fins.

It might work for for a while, but those frayed wires will increase the resistance of that wire, and will heat up at that point.  If it were mine, and replacing the entire wire is not an option, I would cut out the bad section and solder in a new section.

It would probably be fine but I'd suggest replacing the wire, The frayed look is just the insulation but you do need to get it away from the heat. Ya gotta cut the wire to get the shrink wrap on it so why not just replace it? :)

Yeah, sure will.

That's the mag wire so I don't know where it should sit but I'll double triple check it.

I've got crimping down to a science and always use good quality connectors with heat shrink ends.

I haven't tried to solder a wire.

Maybe a bout time I learned...

I'll take another look at it sometime.

I'm not sure there's enough wire out to cut/replace without removing the flywheel which I do NOT want to do.

But... Valid point... That piece does need to go.

I mostly buy non-insulated terminals and dual wall shrink boot w/adhesive - that is how I've done 95% of the wiring jobs the last 30yrs or so. Much simpler to crimp a wire, fire up the mini butane torch and use some good quality rosin core solder to flow out the connection - plus, it prevents corrosion later in the copper joint. Learned the hard working on big rigs and trailers that non-soldered connections will fail in a fairly short time, regardless of shrink boot or none, if moisture can get to the connection point, it's over. While hot, I also dip the connector in a tub of NoOx, it will flow into and protect any type of terminal used on our equipment. I've had the connection tabs rot clean off of lights but the terminal part will not fail - the stuff really makes a difference. You can use the black dielectric grease from auto/hardware stores, it's not quite as good but NoOx is very tough to find/buy.

      Hi,
      I am in need of a Flywheel screen for a Wheel Horse with a Tecumseh HH80 engine. The flywheel has 3 bolt hole mounts and approximately 6 inches in diameter. Please contact me by email with part  availability.

      We're going to take apart the Tecumseh from my Honey's 657 so I can replace the crankshaft.
      Any little tricks or tips I need to know about?

      So I have been working on a 656 I picked up at the end of last year and I did my first ever motor rebuild by my self on it. However it seems that I have lots of play in the piston and some slop at TDC more then I should have. So to finish the year mowing I am thinking of doing a predator swap while I go over the engine again. I am sure several people have done this before and I have a spare mounting plat to make it work. I am wondering if anyone has any pictures of ones they have done for help along the way. I know I will need a adapter to use the factory pulley and I don't want to destroy any of the sheetmetal since it is in good shape. I will keep you posted as I go along and eventually when I get the hh60 back together correctly to re install.

      As stated in another section my honey went and bought herself a 657 a few days ago. Sunday afternoon to be exact.
       
      Runs and drives quite well and had a very serious and non negotiable issue.
      It's Oliver green with Ford gray wheels.
       
      Other than that the work should be minimal standard stuff.
       
      Well of course she started tearing right into the disassembling of the lucky little tractor.
      We started to show the daily work being done to it and then realized we should really start a new thread in the proper location.
       
      So here's a few before pics as a reminder.
       

       

       

       

       
      Here's the end of Sunday results.
       

       

       
      And a pic from Monday nights work.
       

       
      After this was taken she found some spray on paint stripper and emptied the can on it.
       
      We left it on for 24 hours or so.
       
      And found red paint!!
