Title: Broken Speedo Cable - But different
Post by: Dan Cluley on July 22, 2009, 08:55:21 PM
Anybody ever have the outer part of the cable break? (http://www.moparfins.com/forum/smileys/smiley36.gif)
 
There seemed to be a worn spot on one side.  I think it was rubbing on top of the T-bar.  I found some 9/32" brass tubing that fits snuggly over the cable housing, so have spliced it back together with that and some JB Weld.   Used a cable tie to hold it up next to the park cable and it seems to be working fine.

Great idea!

Might be a good idea to wire-tie a support across the "splice" to take any bend out of the inner core as it passes through the spliced spot. Idealy you'd like the core to not touch the outer walls at the splice since any rough spots will quickly damage the core.

Lube that cable with some fishing real grease and it will last forever.  Good idea(http://www.moparfins.com/forum/smileys/smiley4.gif)
 
When the end breaks off the speedo edn of the cable. I just put a hose clamp on it

Cable still had lube on it, so I just put it back in.  After driving a couple of hundred miles this week, it's working, but does have a little twitch at speed, so I will add some more lube.
 
Bill,
I'm thinking that the fit between the cable and my added tubing is tight enough, and I made the splice tube about 5" long, so it should hold the pieces straight.  Because the outer cable is a spiral, the two ends split on an angle.  When I put it back together, I turned them until I felt them mesh properly.

It's probably because the ID of the tube is bigger.  The cable is whipping around in there

Not sure what you mean?  The original cable housing is just the way it was.  The new brass tube is just like a splint holding the two halves of the original housing together.

Ohhhhhh   I thought there was a gap.
 
No, the cable just needs to be lubed up.  You might want to check and be sure there isn't a burr chewing on the core.
 
A sharp bend in the housing can cause that too.  Make sure the sweep out of the trans is about the same as it was.
