New takeoff locker - I'm missing something

[orion]

Yup. That would work. I had only jacked up one side but as BMB said, maybe that wasn’t enough movement to engage.

Hopefully this is all. Have you tried this yet?

Final answer from the shop - electrical all checks good, bad new coil out of the box

Damn! How long till a new coil. Are they exchanging it who you bought from?

2-3 more week backorder.

I did get authorization for the failed one to refund. Just gonna take more time. And a clamshell bearing puller this time...

Ok, reviving this as I got coil #3 and looking for some confirmation.

Before pulling the carrier I noticed the fuse was blown again - I hadn't played with it since taking it into the shop earlier. I noticed the coil that was installed had dropped to 1.0 ohms. Not sure what went on there, but it never had pulled any amps so I guess bad coil is bad.

I've got the carrier on the bench, the bearing off and the new coil on. I can energize the new coil - it reads 3.7 Ohms, and it draws about 3.5A of current - so far so good. It doesn't really pull the locking plate up though. Any idea if this is normal or not? Every video I've seen so far while investigating this, the locking ring clicks and clamps up hard.

I will post some pics/vids when I can. When I energize the coil I can see it move just a bit but I can still pull it off the carrier easily (the bearing is still off). As recommended before - checking for magnetism - it does magnetize the center of the carrier (where the bearing will go). The towers/locking ring has some bounce to it when I check it, it isn't bound or anything and has free play (I think it's supposed to, looking at how it's put together here) — it could just be because I don’t have the bearing on yet too

Any feedback would be great before I stick the carrier bearing back on and make this thing semi-permanent. If this doesn’t work I’ve struck out and will start looking at other options.

EDIT - got the pics up. In the first video you can see the coil jump a little bit when I hit it on the battery (as well as hear it arc a bit when it comes off), but it isn't a strong grab. The last video is with the coil energized. I'm using a lawnmower battery while I have it on the bench.

Well,

Got it all put back together. Got both tires off the ground and turned it on. I heard it click, but it didn't engage - tires spun in different directions. Tried turning the driveshaft to see if that would do anything - nothing.

So now after all of this, I'm convinced it's something with the carrier. What, I have no idea. But I have a coil that's pulling current, just nothing locking. I can't explain why it shorted/nearly shorted the first two coils out (I have a theory, but it's not terribly convincing and I only half believe it - just grasping at straws).

Tearing the diff apart is way over my head - I'm already in over my head as it is here. So - new carrier... at that point I'm just an air compressor away from an air locker really, or a TrueTrac that would cost less.

Since we had a weak snow season this year anyway, I got lucky and never really needed it - heck, maybe I don't need it anyway and this is just my sign. Sometimes you just get bad parts - live and learn, and I definitely have learned a few things in this.

So last batch of parts finally all arrived.

This go around, I was looking at the Spicer parts list for this differential, and I noticed they list a spacer plate between the coil and the locking ring that I don’t recall seeing either time I took it apart.

So I ordered one of those, a new right side bearing, and to make sure this was the last time I was in there, I also ordered an entire new carrier and master rebuild kit (full set of bearings, shims, etc)

So I took it apart, and set the two carriers side by side. Couldn’t notice any difference. The spacer plate was just a thin plastic ring, I definitely didn’t remember anything like that before. But having the original coil still, and the latest coil - sure enough - the plastic spacer ring was stuck up in the original coil.

Just looking at it casually, I just mistook
It for part of the coil and didn’t think anything of it.

With the spacer ring - voila - it works.

Here’s a few pics of what I’m talking about

So if anyone may be interested, I have a brand new carrier, master rebuild kit with bearings and shims, a diff spreader, and a clamshell bearing puller that will be sitting around for a while gathering dust. I could make someone a heck of a deal.

I’ll probably post them in the Sale section later on, but they would cost a fortune to ship.

That is awesome. It sucks, but it is still awesome.

Congrats on getting this resolved. Your patience is admirable. Great thread even though I didn't understand much of it. Thanks for the detailed updates.

If you still have this stuff when I go to regear, I'll hit you up! Truly glad all is well with the axle now!

You got to love it when a good guy wins with patience and perseverance.

Congrats on a Job Well Done
