Your the only person I've seen put proper oil in a wltoys diff! Everybodys videos on wltoys diffs are always packing them with greese, it makes no difference if it's got a lot of greese or a tiny bit of greese 🙄 I always clean all the greese out and put and put oil in. Makes it feel that little bit less like a kids toy when theres some viscosity in there. Great video mate 👍🏻🤘🏻🤘🏻
Don't get me wrong I have packed 144001 diffs with grease. But I wanted to arrest the action of the diffs on this to increase the traction. And it's like you say once the gears have cut a path through, the grease ceases to offer resistance. I know this stuff acts sort of like grease because it's so thick but it does still 'flow' and settle in the case. Time will tell if it does a better job! 👍👍👍
@@theminiatureconstructionco4556 yup, its gotta be really thick grease and packed completely for the gear teeth to be swimming in lots of resistance. diff oil can be thicker, either will work their way out of the diff over some time, centrifugal force wins, it'll seep past bevel gears on the output shafts. after some air has gotten in it'll lose stiffness, oh well! Tamiya anti wear is pretty nice for open gear diffs, its sticky almost like flypaper.
That sounds like a plan. You can go thicker with the oil too without issue. The video was actually shot a few weeks ago when we had a cold snap. It's warming up (relatively speaking) nicely here in the UK. 550 mod is another useful and easy one. 👍👍👍👍
thick grease gives a nice limited slip action the same way, its a little "fun" to pack between the gears really tight, but works great. same for the JJRC diff axles (WPL size).
@@theminiatureconstructionco4556 yup, it'll divide the air right around the bevel gears if there is any, and in time there will be. centrifugal force will always push grease/oil outta there eventually, air gets in.
Great video!! I was looking for a way to stiffen the differentials in 12428 a little bit. Does the cSt 300000 do its job properly or would you recommend a different viscosity? Thank you:)
Hi, how is your experience with the oil-filled diff after some time? Did you think about inserting some seals into the diff to stop loos the Oil? How much oil have you lost and refilled during this time? Would be great if you could provide some experience after a while. Thank you
@@theminiatureconstructionco4556 Many thanks for your response. I'm still thinking about what is the best way to go. I have seen that some also use children's clay. But even then I don't know how durable that is.
Nice video! I like it because of the interesting tweaks in your videos ;-) I am also interested into locking my differentials in 12429, too. If possibile I would prefer a higher locking on the front diff and lower locking on the rear diff as normally in 4x4. Do you have an idea if the "thick" silicon oil decreases lifetime of your differential and axis and bearings because of the higher energy on the parts? It would be great if you can share your experience after a few days of driving and also if you would apply a different setup or keep the same with the 300K oil. Please continue with your videos, good work!
If you wanted a different action front and rear you could use different viscosities. You can get much thicker oil, so experimentation is not out of the question. So far I've had no issues the only one being that some of the oil oozes out of the diff. So periodically you may need to top up. 👍👍
@@theminiatureconstructionco4556 In fact I am thinking which viscosity would be the right one. In the beginning I would like to lock the rear differential only. Do you have any experience what difference is there with an 100k and 300k cts oil?
@@SirMartinusTheGreat I've only had experience with the one type but the heavier you go the more pronounced the effect. You can get a 1,000,000cst oil which I have seen used. 👍
@@theminiatureconstructionco4556 I use EP 90 gear oil for the inner diffs and EP2 grease for the ring gear with a few drops of gear oil to get it stick to metal. Seems to work better than the silicone stuff and it's a lot cheaper. More than 60 packs thru the 124019 and the gears look in mint condition. ..
Hello. I haven't opened the diffs up since doing the video! And there is no sign of leaks on the out side. They are a little less stiff now so may want topping up. The front looks slightly damp around the cups but apart from that nothing. But it is really thick stuff! 👍👋
@@theminiatureconstructionco4556 Nice to see that it's holding up without proper seals! (Or are there already seals?) Do you recommend any other thickness? Thanks for your reply 👍👊
@@joshuamei7465 no there are no seals in them. It's pretty much personal preference with regards to viscosity, and a bit of trail and error! Obviously if it's to thin it will just leak out, I've see people use 1,000,000cst with no issues.👍😉

Not a lot of snow here in tropical Australia but plenty of mud so I'll give this a go while I'm doing the 550 motor conversion . Thanks , good video .

Another great one buddy, really enjoyed this one.. 👍👍👍
Thank you very much sir. Glad you enjoyed! 👍👍
Great vid. Blue tack is the way for me. Doesn't break down like the silicones, acts a bit more like a locker but still reduces drivetrain shock.
What do you mean with "Doesn't break down like the silicones" and "but still reduces drivetrain shock" ?
Excellent advice and a great tip! 😊👍
I loved this video man thank you soooo much keep up the good work!!!!
No problem my friend. Glad you enjoyed it. And thanks for taking the time to comment. 👍
I love 429. I greased mine. It helps. I don’t like the front too tight
It's a good truck. Can't find them now. Used to be everywhere on eBay and Banggood but nothing.
great video my friend👍😎🇬🇧🤟👊😊
Thank you very much sir! Glad you enjoyed. 👍
thick grease gives a nice limited slip action the same way, its a little "fun" to pack between the gears really tight, but works great. same for the JJRC diff axles (WPL size).
I find that once the gears have cut a path through the grease the action becomes limited. The oil still flows slightly and sticks to the internals. 👍👍

Very useful, I'm gonna try this on my MN99, thanks
You don't need too. They have solid axles, no diff. 👍
@@theminiatureconstructionco4556 Well thank you, I honestly didn't know that. Excellent, I love my car even more jeje

It does to a certain degree. You can get 1000000cst oil, so it's a matter of trying a few grades. 👍
How about just lock them up with glue?

It has oozed a little bit out. But I'm not exactly sure of an amount. I'll have to do follow up video eh? 👍😉
Interesting video :-) Did you lock the diffs front and back? Will that also hold up in the long term?
Both diffs where filled. I have noticed that over time some of the oil oozes out. So periodically the diffs may need to be topped up. 👍
