I got a used 40970 off of ebay recently and took it all apart to clean and lube it. With the internals put back in the selector switch doesn't sit flush to the back of the ratchet as I think it should (could be wrong, first SK ratchet), and there's a good amount of play up and down and front to back if you grab the drive and try to move it. Is this normal for these ratchets? I have a picture of the back of the ratchet, does this look right?

That's what I was thinking, there's a lower groove but I've been fighting with this thing for on and off for the past hour and I can't get the ring into that groove even by itself and leaving the drive assembly out.

Does it have a rebuild kit in it?

I rebuilt two of those, and it could have been just me but I could not use the snap ring from the rebuild kit in either one. I had to use the original snap ring in both of them.

keep twisting the switch and entire head until it pops down in where it's supposed to be.......it's gotta be positioned just so for it to fall down in there. If I recall correctly..........put the direction switch in "neutral." Put your thumb on the drive side pushing down as you twist the head.

is this the same guts?
Suspect snap ring in wrong place as Jawn mentioned, they can be tricky to set.
Picture of bottom will tell.

:thumbup:Rarely do they go in correctly without doing this.

Sam, I'm not sure if it has a rebuild kit in it or not. twertsy and bill, I'll give the spinning a shot. If I can't get it back together correctly I will post up some photos. Thanks for the help so far guys.

I've found that when reassembling ratchet parts that pass through the head, It helps to set the head over the hole in a roll of electrical tape and support the handle. This lets the guts sit all the way down in the head without interference from the table while setting the clip.

So I think I've figured it out, the clip doesn't seem to be wide enough or is the wrong one to actually hold the drive in place. I tried to get a picture showing this, but my phones not great at close up shots. Maybe the whole internals are wrong as well? I dunno guys, let me know what y'all think, and thanks for all the help.

To me it doesn't look like the drive gear and selector switch are far enough in to get the wire clip seated. It looks like the selector switch needs to be flush with the ratchet body. Here's an ebay link showing the selector flush. http://www.ebay.com/itm/3pc-SK-Tool...70-1-2-42470-USA-Chrome-S-K-S-K-/282133934537

Try changing the selector switch wile installing and putting downward pressure on the assembly. If was right when it came out, it should go back in right.

There are two different sized retaining rings for that model. The newer rings will fit all of them, but, the grooven in the ratchet head and on the internal part must me cleaned. Clogs of dirt or rust will make them hard to take apart or put together.View media item 62920

3bay, it was all together but extremely packed with crud, and this is the clip that came with the ratchet.

jacked, in the pictures I have the drive being pushed up to show how the ring is not retaining it. I really didn't pay too close attention to the ratchet when I first got it was pretty dirty and am thinking that when I got it any amount of play was minimized by all the old grease/dirt that was in the ratchet as it was quite a bit I cleaned out, or I just plan didn't notice because I was too excited about a new ratchet :lol_hitti.

raider, thanks, I think my best bet at this point is to get in touch with SK and see if it's possible to get a replacement ring. I planned on converting this to a 3/8" drive originally with one of those 45172 thumb ratchets that pop up time from time on ebay for $10 plus shipping. I'm assuming the clip from that ratchet will fit as well?

Again, thanks for all the help everyone.

Did you read all the posts??

Put the selector in neutral and press down on the drive side while spinning the whole mechanism........it must be in neutral to slide down in correctly. Fun part is while doing all that, your third hand needs to manage the retaining ring.

I'm guessing it was assembled correctly when you got it.

I would say don't hassle SK for a kit when it likely just needs to be assembled correctly.

Yes, I read all the post and have been putting the drive selector in neutral every time I've tried to reassemble the ratchet and I've tried spinning the drive as well with the ratchet handle in a vice to free up a hand.. Is this the correct groove for the ring to sit in?

There should be only 1 possible slot once the head seats. The inner ring will be unavailable.

First, center the selector, which basically puts the ratchet mechanism in neutral. I like to put a small dab of grease on the underside of the disc to sort of glue it in place, it makes one less part to have to juggle as you are putting everything back together.

Next, put the retaining ring in the groove on the ratchet mechanism and squeeze the ends together with needle nosed pliers to compress the ring.

Then insert the ratchet mechanism into the head and make sure that the retaining ring is in the grooves in both the head and ratchet mechanism. Sometimes the ring can be kind of a tight fit and might take a little bit of wiggling, twisting, and pushing around to get it to go into place.

As long as the pictures post in the order that I intended, they should help explain.

The ratchet pictured is a Mac X3r, which is basically just a rebadged SK 45170. The internals are the same as your 40970, just larger.

It almost looks like you're putting the retaining ring in the ratchet head first, based on these photos.

This really makes me think you're putting the retaining ring in the ratchet head first. The retaining ring goes on the mechanism while you're assembling it.

Do it like this guy is showing. That's how I always do it.

But I'll add one additional bit of info. I hold the ratchet handle in one hand and poke my finger up trough the hole to keep the dial held on the back of the ratchet mechanism.

It is all in how clean the retaining ring grooves are. The internal groove gets dirt and grease in it and will not allow the ring to compress enough.

Hey guys, so I have been compressing the ring over the drive gear with it in neutral during assembly. I had watched the video you posted SMKS and also another one I found through google. :dunno: I even had a friend of mine mess with the ratchet and the only thing we can come up with is that something isn't right with the snap ring.
