I recently started using my Proto Big-Dawgs more and it seems that they want to change direction on their own more than I'd like. What causes that? Is there a way to stop it?
Why do ratchets self-reverse?

You've gotten a broken ratchet; send it back to Proto for repair ..

The simple motion of the pawl moves it towards reversing anyhow for pretty much all the designs out there. Once in a while, the conditions could be right to basically eject it over. If it does this a lot, then there's a problem. Bad spring, etc.
The Proto ratchet is a very good mechanism and rarley goes wrong.
If you put the reverse lever in the middle (neutral) remove the screws remove the gear then turn the reverse lever to on or off and remove both dogs and springs give it all a good clean, If all the parts are in good condition rebuild with a few drops of very light oil (air motor oil is good). all should be well.
If the dog springs are weak then they will need replacing.
The major problem with this type of mechanism is that people ram it full of grease or heavy oil and it just clogs up.

Or they fill the head with engine assembly lube?
I think you might be thinking of the older style. The Big-Dawgs have only one spring and one pawl.
Well, yes- that it what I was thinking could be the problem... bad advice from Merk!
I don't have much of that stuff in them, but there is some. Maybe I'll clean 'em out and start over...

If thats the case then I stand corrected.
It's a shame they are not using the older style as it was as tough as a scrap yard dog.....on steroids

Mine is pretty basic inside, but neither one has ever reversed by itself. My 3/8 long has reversed unintentionally a couple times, but it's from bumping the selector in close quarters.

Mine do it too. Kind of aggravating, I think it has to do with the fact that the pawl spring is pretty weak on them.

Yeah, your pawl springs are too weak ... or in the case of Proto ... your dawg springs are too weak.

my snap on ratchet (either) T72 or TL936 are work normal and dont do that to me. Craftsman ratchets do a lot to me that why i throw away (took it to home as home use)...

too much lube picked up too much **** soon it will free wheel on it's own.( no drive)
Well, I took apart the 1/4" drive today (the worst offender), wiped off most of the Permatex and put some ATF in it. So far it seems to have helped.
It seems that the Permatex is just a little too sticky for the tiny spring in the Little Dawg. It was pretty cold when it was doing it too.

Yep, I had a ratchet that kept reversing. It works fine now after I stretched the spring a little and cleaned out all the grease and used a light oil instead.
My first attempt to fix it involved adding lots more grease which made it worse. (How I usually fix things!) That was the clue to try going in the other direction with the lighter oil.
