Cleaning/greasing gears on 1/4" Snap On Ratchet

[PECVD2]

I picked up a Snappy PM-70 Midget S-34105 (?) 1/4" ratchet.

It is sticky and sluggish. I want to pull the gears, clean and re-lube.

I pulled the two screws out of the back and tried pulling to get things apart.

Is there another snap ring or trick in getting these apart?

Also what would you recommend to clean the grime/small rust off of this beauty?

Any help would be greatful.

Sometimes the coverplates are stuck. They can also be brittle and break, so go slow.

I'd try soaking it first, then rapping it against something solid, like a vise. Strike the ratchet drive side down.

Mine just pop apart...but they aren't very dirty. Some WD-40 might help get them apart.
Clean them with brake or carb cleaner then lube them with something light like 3in1 or MarvelMystery oil.

Wrecker,

I will try that thanks. There are just the two screws...right?

 

[wreckercologist]

Yes, two screws. The pawl should not come out with the gear. The pawl will stay in the ratchet body, so when it is finally apart, you will have two screws, a coverplate, and a gear.

The only time the pawl comes out is when a new kit is installed.

take a brass punch, and tap it out from the top., will pop out. (sometimes you will have to more than tap it)

For old ratchets its usually a few day process.

-I take them apart and soak the head in degreaser overnight.
-Then I take them out of the degreaser and parts wash them with brake clean.
-Then I soak the parts in gear oil overnight.
-During final assembly I coat all the parts in super lube, or moly lube and give a nice squirt of the stuff inside the head before putting back together.


Works like a charm everytime.

I had to take a punch to the backside of the drive gear to get mine to come apart. Once it loosened up I was able to knock it against the top of my workbench a couple of times and it popped off. I took some steel wool to the edges of the cover to knock off the crud that had accumulated and was making the cover stick.

Thanks all for the tips and information.
I got it apart and it was just loaded with grease/dirt/gunk.
Cleaned up all my little fellas.

LOL yeah he evidently has had a rough life. But that's all behind him now.

He is retired, but could use a transplant so if you have the part #(s) or know where to get the necessary components please let me know, as I have never even stepped foot on a tool truck or ever purchased a new Snap On item.

On minor rust...I really strongly suggest evaporust because it really has no effect on remaining plating and unlike all acidic types it has no effect on springs, meaning that if you don't need to replace spring you don't have to worry...acids, including phosphoric, can completely ruin small springs.
