Speedometer driven gear

Hey guys, getting pretty ticked off right now I'm not going to lie. 1978 2wd 300 6cyl 4 speed manual transmission. I cannot get the stupid little clip off of the output shaft. I really didn't think going through this whole process that this little clip would be the hardest part but here we are... I can work all of it off with a flat head except for the very tip of the opposite side I start on... how have you guys gotten these things off?

The C-clip on the driven gear which lives on the end of the cable?
Or the drive gear, which lives on the output shaft?
The C-clip, which secures the driven gear, comes off easily, just prying with a flat-blade screw driver.
The drive gear is likely held on by more of a snap-ring - at least that's what I remember seeing in a T5 5-speed - although it's been 7 or 8 years...
If your 4-speed is like a T5, then that snap-ring can really be a PITA, even with some cheap snap-ring pliers like mine. But it is doable. If you can find something small enough to fit in the holes, and strong enough to expand the ring, you might be able to get it, but I'd recommend just picking up some snap-ring pliers. The more well-stocked McParts stores might have some in their tool section.

If this answer is no good, can you post up a pic of the gear and clip?

Ahhh I always get those confused.. in that case it would be the drive gear, and I have the snap ring pliers but the thing is, of course there are no holes on the snap ring to fit the ends into... I'll post a picture tomorrow.

I'm at the point where destructive forces will begin being implemented...

It looks like you could pry up on that tang seen at the 4:00 position, and have it slide off. Is there another tang 180º from the one in the picture?

that's a reflection on the output shaft, it's a snap ring, that is the gap in the snap ring you're looking at

OK, gotcha. That tang probably wouldn't move far enough before snapping anyway.
I'd maybe try sliding some knife blades or something under the gear, in order to get a little off-ward force on it, and then try spreading the ring. Or you could try those implements directly under the ring.
Have you gotten the ring to spread far? Maybe that style of ring takes a special spreader?

I'm surprised no one else has chimed in, I'm sure several others have been there in one of these. I'm pretty sure the T5s had holes in that ring, but it still took a little patience...

The more I think about it...
If I've ever gotten one of those off, it was by spreading it and working some sort wedge underneath it in order to provide some force to push one end of the ring up or down the shaft, and away from the groove. Every time you make some progress, you stick something under that portion of the ring, blocking it from lining back up with the groove. If you could fill the newly exposed groove with something like some solid wire, that might help to keep the ring from snapping back in. It can be slow going, working your way around one of those rings. That one looks strong...

I got the little jerk, here this is what I was having problems with! Idk what I did that was different from what I was doing but it popped out of the groove it was in. Think I stretched it out a bit, it went on pretty easy and it wasn't as tight as it was, hoping it don't pop off

That type of snap ring needs this type of plyers.

I am sooo getting a pair of those! This project would've been about 4 hours shorter lol so I took for a spin and ... my speedometer isn't moving and my odometer is going backwards lol so I take it I need A driven gear with the teeth going the opposite way? The speedometer hasn't worked since I've owned it so I don't know what is right on it and wrong there. I know I put the drive gear on right being it would only go one way

this is pretty much what I did, spread it open and wedged it out

If you have mismatched gears and the teeth aren't pitched the right way they will quickly eat eachother up. I mistakenly put a driven gear from for the top loader in my '68 Cougar in the T-case of my pickup and ruined both gears.
