Frozen cables - not FJ related

[FJmonkey]

I have a problem that is not directly FJ but it could be MC related for cold weather conditions. Snowmobiles and ice racing etc...

I have a push/pull cable assembly I use under a full size van. The cable raises and lowers a metal latch bar as a lever is rotated. The cable is spring loaded to allow for self return/reset. The cable is protected by a spring preventing overload. However, when the temps drop, the cable freezes inside the conduit. It all works well once thawed. I was wondering if a cold weather lube or treatment might be an option.

Has anyone solved a freezing cable issue like this?

Do you think it is a problem with moisture freezing in the cable?  Or a problem with cold temps reducing clearance enough to bind a little? 

If moisture - I'd try flushing with WD40 and then follow up with a spray "dry lube" - google turns up some options that might be at car parts or home supply places?

If strictly temp related - maybe try some of the water pipe heater strips.  Mights have to have a 120 volt inverter though?  https://www.homedepot.com/p/Frost-King-6-ft-Electric-Water-Pipe-Heat-Cable-HC6A/202262328
Someone might make a 12 volt version for similar auto (RV?) use?


Another line of thought - how old is the cable?  Has it worked while for a few years and is now causing an issue?  Might be as simple as replacing the cable every few years?  It sounds like it lives in a pretty rough environment?

I am guessing moisture is the primary issue.

I'm thinking WD40 to do what WD40 is suppose to do - "water displacing".  Then maybe a dry lube to provide lube properties which WD40 is not nearly as good at.   

I'd also assume the fluid they use to suspend the dry lube wil also evaporate pretty quickly and should remove any remaining moisture - at least in my mind!

It seems almost like a throttle cable. I wonder if you could have one made long enough and run it outside the conduit that collects water.

Is this small sheath cable like the throttle cable or larger cable?

I am with Chris and Travis that moisture is freezing inside the sheath.

Are the ends sealed?

Can the cable be removed and greased?

Can you wrap the cables to insulate?
