I need to remove the knob on this style wiper motor. I've pried as much as I dare and attempted to unscrew without luck. Appreciate knowing how someone has removed one without damage. Ron
Ron, if/when you break it off, look at "guitar amp knobs" for lots of cool vintage knobs. It's a thing. https://www.tubeampdoctor.com/en/parts-for-amplifiers/p***ive-components/pots-knobs/amp-knobs/ https://www.parts-express.com/tools-supplies/hardware/knobs Amazon has a bunch of hits too. Hope the shaft is something common. Mike
I just bought one of those a couple months ago and installed it behind my headboard. I needed to install a separate switch so I tried removing that knob with no success. It will break, it has a strange cheap plastic connection, not anything you’d expect, the knob reaches clear inside the unit. I ended up leaving the switch to the on position and running the Hotwire to a separate switch.
My squirters location is a personal matter. Right away I was thinking you guys were talking about a truck bed. Creeps.
You could try playing a heat gun on there, just carefully so it doesn't start burning, and try prying it off. Although it sounds like it is a thermoset plastic, so heating it won't do a thing. If you don't care about keeping it, bust it off. Replacement knobs would have a grub screw ,or the shaft could be a metric spline, knobs available for these, too.
Does the whole top cover come off?, from memory (on an older but same looking w/motor) the cover was able to be removed, and a clip was on the inside securing the switch pivot..
Whole top cover comes off with that one screw. The switch is a piece of copper that hits the contact .
