Ratcheting wrench lubrication test
Backdrag is one of the most important performance metrics for any ratcheting tool. In this video I try out some lightly used ratcheting wrenches that had soaked overnight in two different kinds of lubrication: PTFE/teflon chain lube and white lithium grease.
I tested wrenches from the following sets:
Proto JSCVM-20SA
SK X-Frame 80019
The results show a slight advantage to one of the lubricants used over the other (and the control wrenches, which were left as they were from the factory), but there may be other problems that I run into later such as autoreversing, binding, or skipping. I'll make a followup video in that case.

Using oscilloscope to test oxygen sensor on 1991 Geo Metro
Просмотров 2664 года назад
Backprobing the single-wire oxygen sensor on my 1991 Geo Metro to display its trace on a Tektronix 475 oscilloscope. Approximately 0.1 volts per division so you can see that the oxygen sensor is functioning normally. While digital scopes and scan tools can diagnose O2 sensor failure fairly well, the response time on CRT scopes is the best.
Your setting seem better than mine... What's your A/B sec div setting? I struggle to see the movement like you on a Tektronix 2215
Pretty slow! gotta be about 5 seconds, 0.1 volts per square, and very high intensity to give it a trail
Need to put them in a vacuum chamber 😂 Then the grease will actually be sucked into the gears.
Tempting! I do have a Yellowjacket vacuum pump that works quite well
PTFE is a forever chemical probably the last thing you’d want to be putting anywhere where it may touch your skin or have any chance of entering your body.
I usually inject Super-lube oil (with PTFE) using a syringe with 18 gauge needle on my box end ratchets. I haven't broken any ratcheting wrench and all work like brand new for over 20 years.
I don’t lube them haven’t broke any used them a lot still working like new
I've invested in my first set of ratchet spanners, US Pro brand. Some folk say you shouldn't lube them. I believe you should due to the high loading forces on the ratchet's metal to metal moving parts. Came to YT to see how best to lube them and I would consider soaking the ratchet heads in diesel because its thin enough to seep in and is also a lubricant.
Most good ratcheting wrenches have some light lube from the factory, but I noticed a definite improvement when soaking. I would consider ATF over diesel, and the teflon-based spray was the best long-term. I need to do a followup video, as the white lithium grease gummed up quickly.
@@wrenchposting9097 I'll have a look at ATF. thanks!
was looking for something else but I won't complain 😸
Any chance you've figured out how to disassemble the Proto wrenches? I want to try to smooth out a sticking switch on one wrench in the set and don't see how to squeeze any tools or wedges or hooks inside the tiny gap to get the ratcheting mechanism apart. One video shows how someone took apart the Gearwrench using a razor blade to get down in the groove and remove a retaining ring / lock ring, which allowed it to come apart, but again, I don't see enough of a gap in the Proto's. Unless one uses a piece of narrow-gauge sheet metal. ruclips.net/video/9xDYVgIkfDs/видео.html and ruclips.net/video/dC2CD5wP3aw/видео.html
When I first bought the set, the switch on the 24mm stuck pretty bad but I just flipped it back and forth over and over while moving the ratcheting ring a little and it started working fine. I wouldn't attempt to disassemble one of these unless it was otherwise unusable.
@@wrenchposting9097 hmm, that's the exact same one I'm having issues with. Wonder if the person on that assembly line making the 24mm's was a dud. Production code "3U"? Ok. "Work it in" it is.... thanks.
@@ronc4146 my 24mm is "3T" so at least adjacent if that's how the production numbers work.
@@ronc4146soak it in gasoline . Get it working. Then soak it in atf.
Any update on the longevity of the lubricants? Have either gummed up and caused any troubles?
yeah I need to do a follow-up video, the white lithium grease did gum up the SKs. The PTFE-based lube was way better in the long run.
@@wrenchposting9097 I’ve just been using the old ATF method. In all honesty i was hoping the white lithium worked out. Purely because it’s like nails on a chalkboard hearing the metal in that gear hit so hard.
You need a scale to measure the force involved.
That would be worth my time if I was comparing the same size wrenches and not 14mm to 15mm to 16mm...beyond the scope of this course, as they say.
