Talion V4 diffs and servo saver

[Primarrma]

Happened to me when i (accidentally) sprayed some cow-slick on those parts, it makes them slip much more easily. Only fixed after i took it apart and cleaned them, now i run the SS tighten normally (4-5mm from the chassis) and it doesn't slip.

I assume that this reply was to my comment? Thanks mate that's great info, I've got a few new parts coming for my cars, so when they arrive I'll rebuild them completely and do as you say thanks again. My Kraton is a heavy brute when my m2c arrives it's only going to get heavier, I need as much steering as I can get.

If you have a decent servo, run the nut almost all the way up and loctite it there. I've never stripped out my Savox with it run up high. And it turns really well.

It isn't loosening off, it's slipping at the plastic, I've got it really tight, but it still gives way, I'm running decent servos they are over coming the servo saver under load. It is frustrating because the car won't turn at speed on a high grip surface.

yeah, it’s what happened to me as well, servo saver tight, yet it stills slip (i could clearly see the two parts slipping).
Only cleaning it from the moo-slick (it might have even been wd-40) solved it.

I run my Typhon with the saver pretty much all the way up. I’ve put ptfe tape under the nut and it’s not moved or caused damage for 10 packs, on a ruff track with hard driving

The way I have mine, it doesn't slip at all.

I think it must be worn out, or damaged, the spring may be softening? I've got the new one coming I'll see if it's any better.

 

[bicketybam]

As suspected the V4 servo saver is not adjustable and it was stuck together with a ton of loctite.

Also, there is really no way to push down on the top to grab the nut. The spring is too stiff. I had to use vice grips to hold it and it marred up the top half of the servo saver.

This is a set it and forget it design. You are not going to want to be pulling this apart. I'm glad I got a V3 assembly coming. This one is going in the bin.

 

[bicketybam]

Servo saver hub is 12mm in diameter. The washer it comes with has a 12.21 inside diameter and a 17.88 outside diameter. It is 1mm thick. It is part of the servo saver hub assembly so you will need to source these on your own if you want to use additional ones to tighten up the spring.

 

[Primarrma]

Thanks for the pioneering, it is helpful for someone to go through the pain first. Bit of a step backwards really isn't it. Shame because I truly think some of the other ideas are an upgrade(like the larger heads on the tie rods). As you've said before it's either a case of cutting costs or we need to be careful what we wish for.

Great stuff again, thanks for the info mate!

What do I need to order to use the V3 servo saver on a V4?

It's probably best if you just buy the whole steering assembly from a kit breaker like Jennys Rc. They're out of stock at the moment, but if you keep an eye out, they come up often. Be sure to pay attention to the model number. AR106021 refers to the older versions, and AR106040 refers to the new V4's

How are they shipping you shims that aren't available for purchase yet?

I'd confirm the part # with them...

I sent them the part number for the shims. I'll see when they generate the invoice. I'll keep you posted.

Doesn't mean they don't have them manufactured and in stock. They have to have ones that go into the actual kits already. They just might not have the packaging completed or something for retail distribution yet.

All the parts for the RTR kits would be shipped in bulk to country of origin, which is somewhere in Asia. The packaged individual parts would probably take longer to arrive at Horizon for distribution.

The v4 has the updated tie rod washer heads, so you'd preferably swap them off your your kit before installing the v3 steering assembly.

Does the v4 still use bushes in the steering posts, or have they used bearings?

If you watch @bicketybam's new video, he breaks the whole V4 servo save down. Still using bushings.

I will get around to watching it soon, thank you. It's good info he's getting out there.
