Locker Case Gasket

[keithgemmill]

How important is the gasket that is supposed to go between the bevel gear and differential case? and if it is very important where can i purchase some? im putting HD bevel gears and aluminum diff case in my axles

[keithgemmill]

also what is the proper grease/lube for the bevel gears locker and trans gears i bought.

That gasket is not needed. As for grease, any automotive grease will do. I use Castrol Red.

Mobil 1 synthetic will work great and will not break down the plastic axle halves.

X2. I use it in my axles, trans, and dig.

But for twice the price of that little plunger full of grease, you could go to Autozone and get a small tub that has enough to last you the rest of your life.

Yeah, exactly. I bought what I could find here in China...and it is a TUB. Oh well. I have enough grease to lube 1000 crawlers.

Yep, been using this for over 2 years now.

I beg to differ! Without the gasket the ring gear and diff case assembly is a little thinner and it can float sideways between the bearings. Then the ring and pinion gear mesh will open up a bit, which will lead to noisy gears that wear out faster.

You can make something out of thick paper or thin card stock, good enough. Any shop that sells Axial parts should have them too.

Cheers.

thank you all so much the last time i asked a newb question like this i got yelled at and made fun of. thanks for all the help i think im just gonna get myself a big tub of mobil 1. and as for the gaskets i found some on tower hobbies. is there any way you think i will be able to use my stock ones over again tho and save my new ones.

I've had mine apart a few times, always reused the old gasket. Its just a rubber ring.

Rubber?? I must be thinking of a different gasket....I thought he was talking about the paper one.

its so thin, it really doesnt make that big of a diffrence

Guess I haven't had mine apart as much as I thought I have.

I could have sworn there was a rubber o-ring. Maybe that was the TMaxx diff...

[keithgemmill]

yea im talkin about the white paper one axial #AX30385

Even if it tears when you pull it apart you can just put it back as is. Just be sure the orientation of the parts is the same, and don't lose or remove any of it. It isn't sealing anything so it's not that critical from that point of view, it's just to maintain dimensions.

Yeah, I was. It's actually proper gasket material.

That's right, it doesn't. The truck will still run. It's about .05mm but those are smallish gears and that little difference can really affect the mesh, they'll run rougher, make more noise and wear faster. The gasket is easy, why not leave it there?

Cheers.

i agree thats why i ordered two new ones and bought myself a tube(size for grease gun) of mobil 1 synthetic for $7.99. how much grease should i apply tho? would anyone have a build pic by chance?

Fill it with grease! Pack the bearings, grease the pinion shaft before installing it, fill the locker case before closing it, fill the ring gear with grease and put a bunch more in the housing then drop the gear in, put some more in the other housing half and close it up. Wipe off the outside afterwards.

In other words, fill it!

Cheers.

That will be a waste of a lot of grease./\/\/\

All that's needed is a light coating on the gear teeth.

This is a well timed thread. I recently purchased different ring and pinions and was wondering myself what to use for grease. I think you did right by replacing the gasket too. I have noticed that just the small amount of wear on my current ring and pinion have made it a fair amount noisier. For the noise factor alone I would want tolerances as tight as possible.

Again, I beg to differ! The tiny bit of grease you have there may see you through a few hours, but my own experience tells me that is nowhere near enough for the long term. Is that grease really expensive? Why be so frugal?

So maybe my way of filling it is a bit over the top, but I still say more is better. Grease dries a little with use and exposure, and when it gets dust and debris from gear wear. It gets squeezed out onto the housings, where it stays, away from the parts that really need it. It can get abrasive when dirty. It loses it's stickiness and doesn't flow so well. All good reasons to put more, not less.

I coat all bearings and metal parts, whether they move against each other or not, to lubricate and to stop corrosion, and I fill cavities to exclude water and dust. A big blob of grease is less likely to dry out, and handles contaminants better too.

So maybe you don't need to "fill it!", but I believe you do need a lot more than a light smeer on the gears only.

Cheers.
