wd 40

[dr. d]

WD40 is overrated, has very few legitimate uses it's ok as penetrating fluid and as a solvent. but completely $ucks as a lubricant. extremely bad for preventing rust

from what i understand, after reading the WD40 literature,
it was not designed primarily as a lubricant.
it was designed for loosening stuck joints and bolts, water displacement (for wet hi tension circuits!), cleaning of dirt, and other ingenious uses.

one can find these other ingenious useful uses for WD40 in google.

i once would spray WD40 onto my squeeking fan belt tension pulley.
it would initially work as an anti-squeek agent, but the squeek would return after 2 weeks or so.
truly, a lousy lubricant.
i had since made a more permanent solution: replacement of the idler assembly.

i also used WD40 on my bintilador bushings. it worked, but only for a couple of weeks.
i also tried singer sewing machine oil. it would also work, but only for a couple of weeks.
the more permanent solution to bintilador woes, is replacement of the entire bintilador, or the bushings/armature.
