What have you broken?

[BrotherAndySLB]

My 2 speed trans has been popping lately, I've taken it apart multiple times trying to find a reason, never could.

Well, on the trail Thursday that popping led to first gear going out.. Then shortly after lost 2nd.

This is all that broke:









This is what it left behind:



Also, the rear input shaft bearing was toast.

Total carnage:



I put the single speed parts back in changed the bearing and its back to smooth as silk.

Other than this (really not stock), all I've broke are the non-hd driveshafts.

------------

On another note, a friend I work with just built an Ascender kit, on the trail today this happened:



Yes your seeing that right.



Both the upper and lower links bent horribly.

How? Well, my summit and his Ascender kind of collided after I broke a steering link on the Summit. Honestly, it didn't look like that bad of a hit, just slid the Ascender backwards a few feet. But those links are trashed now.


So what have you broke?

A failing rear tranny output bearing may have been the start of your gears stripping. EDIT: I see now you were running the plastic TwinHammers gears, time to get steel Ascender gears as Itali83 said.

I've not broken anything...yet.

EDIT: I would inspect the tranny case inside and out for stress cracks and check that all bearings and shafts are snug fit in the case, may have damaged the case over time or at time of gears chewing up.

Dang, that tranny is smoked! Time for metal gears. I've just lost my input shaft bearing that I think was just a defective bearing because it went bad with literally 2 hours on it. I stay close to my rig though on steep rocky sections and don't let it fall to are st list some guys do. I always catch it if it starts to tumble. I'm not that hardcore and worry about the "touch" factor.

The only casualty on my Ascender has been the intermediate shaft that goes between the trans and transfer case with my GCM setup. Plastic shafts clearly do not cut it there but I have a steel replacement on the way.

Here are the two links removed:

I broke my driver side RULR today. Snapped right in two.

In a year I've been impressed at the lack of breakage.

This far: stripped plastic servo horn. No surprise their.

Lower suspension links are slowly bending themselves. This is actually helping the rear pinion angle. I'm going to keep running them till they get real ugly then make some 3/16 stainless solid stock replacements with larger 4mm Revo ends so permanantly solve the issue.

I managed to twist a non-hd driveshaft just a smidge so that it woudn't slip in or out. HD replacements have been flawless thus far.

Worn out a couple sets of panhard bar rod ends to where the looseness was effecting steering ability since it would shuck the axle side to side instead steer. They are easy to replace, so I keep spares on hand. I'm sure the 400+oz/in servo attributes to the rod end wear.

That is a really short list for me and any RC after a year.

I was highly skeptical of the plastic knuckles/c-hubs, but I'm not replacing them till I break'um.

If needed, you could straighten those links in a vice and keep in truckin. Don't get run into by trucks weighing 3 times your own and it will be much harder to bend them.

I believe my truck is getting close to being a year old now. It is the non-HD version rtr.

so far I have taken out a front non-HD shaft, and a front non-HD ring and pinion.

The body is looking pretty beat, but so far so good otherwise.
