Blinker Fluid

No one does SAE anymore....!

 

And then, there's British Pipe Thread. I still remember being told that the lubrication system on the brand new bundler system at the steel mill I worked at in the late 1990's used something called British Pipe thread. I have never seen it used anywhere else. I have never heard it mentioned anywhere else.

If I remember right the threads per inch were the same as standard pipe thread, but the pitch of the thread surfaces was different.

 

sae-nf or sae-nc all the time. At least it isnt modelers or british threads with its 50 degree pitch

 

When you drain the old stuff it may get a little creamy as it leaves the whipper valve.

 

I thought everybody knew that blinkers went out of style a long time ago?

 

Seems that one of the auto parts chains has a coupon for a free bottle every other week. Should be no reason to ever run out of blinker fluid with that.

The blinker fluid fill tube is located just below the locking mechanism on the 5-th wheel. Need to drop the trailer to access it. I think they wanted to keep it in a safe place because it is so crucial.

It's recommended to drop your pants and underwear (don't want to get them greasy) and sit directly on the 5-th wheel so you can get a good view without straining from the side. If you don't see the fill tube; then keep sliding back and fourth on the 5-th wheel until it becomes visible. It may take some time, be patient. Good thing your not wearing pants.

 

Don't forget to change to summer air from winter air in all your tires after you change your blinker fluid.( It's good to do them at the same time as to not forget one.) Also, be careful not to snap your muffler belt when filling the fluid. It's been known to happen...

 

Full explanation starts at 3:54. Also worth watching if capacitive reluctance has increased fluid consumption beyond recommended quantities.
