Pinion gear

[BJoe]

Well, it was worth a thought at least.

[plyr2k]

Took it all apart, pulled out the chunks, used one of the extra halfs of drive shafts after it exploded that too, it's short and barely engaged, but works. Been playing with it. I'm surprised it still works, fine. I will call Vaterra tomorrow. See if they'll warranty the shaft and pinion.

Come on vaterra team! Show us your still listening by releasing a hardened steel ring and pinion already! Everyone i know that has an ascender has been through at least 1 set that looks just like those

Hi Guys,
Again this is pretty frustrating for both you and me. I'm very aware that this is happening here but we're simply not seeing the numbers through our customer service line. I am working on making a set of "HD" pinion gears to support those running bigger power etc.

Please keep in mind that I don't doubt the issues here but based on the number of vehicles we've sold (which I obviously can't share) to the calls and emails regarding this issue it's relatively small. As we all know, a problem on a message board can be made to be much bigger than it actually is.

It's been our/my goal to always provide the best product we can and we will beef these up and as we progress I'll share with updates.

Don't beat me up too much

I have run mine 4 times now and still no gear problem. I did break the pin in the front axle cv. I think this was due to the angle of the shaft, and also the axle does rock back and forth a lot. I'm coming up with a modification when I have time to reduce this rocking, but am busy with work at the moment.

Great to hear that the hd gearset is in the works! Thnx for the quick response and hopefully they will be available for purchase before i break my next set. Just to be known my last set broke before the stock shafts let go with a recommended 5 1/2 turn set slipper with an axial 27t on 2s. Thnx again for listening i know we have a few guys here looking forward to the hd set aswell.

The two shims that come in the kit to go either side of the spool behind the bearings. I don't know if they are available separately, but I put both shims behind the drive side bearing as there seemed to be too much play with one each side.

Granted I'm only running 2s on a 55 turn, but I'm pretty hard on equipment.

I have probably 4 hours of use on my Ascender now with no parts failures. I've had it horrifically bound up to the point of stalling the motor (yeah, slipper is probably tighter than reccomended), and hopped it on rock ledges at WOT just to see what it will take in terms of abuse. So far it's getting an A+.

BUT, I did pay attention to the ring/pinion mesh when assembling and found that I needed three shims behind the ring gear side, and none on the other side. The kit only comes with 2 shims per axle, but fortunately I have a ton of shims on hand.

I'm starting to believe that many of these gear failures are the result of too much back lash in the gears. They are small, so they need to fit together as snugly as possible without reducing the clearance to 0.

I'm about to drop in Hera's Pro4 4000... hehehe

Yeah, got to agree with you on that. I did have some small shims somewhere and thought to try shims behind the pinion. Can't find the shims lol. More on order anyway. I think if there is any difference in the axle molding then this could cause a problem. It may pay Vaterra to include extra shims in with the kit perhaps, plus an advisory to check play on the diff.

I just joined the broken pinion gear club! :( Broke my front pinion on first run about five minutes in on first battery. Two teeth broke and bound axle and then snapped driveshaft. Only running Tekin fxr/35T on 2s. Will put in a call soon.

[old man 52]

Well that pretty much answers my question. Sorry for all of you guys that are having these problems. Is there any new on any of the after market companies looking the cash in on this yet.

[M1tch]

I hear that Vaterra may be bringing their own HD set out, but don't know any date yet.

[Jimbow]

They need to hurry the f up with them. This is bull crap

I call one of my local hobby shop's and ask if they heard anything about vaterra coming out with HD gears' He said no but wish'es somebody would , He told me he can't seem to sell them at all now.

[djjiz]

The 2 we had sold from our hobby shop are both broken. Gear failure plus noob trigger finger resulted in broken drive shafts as well.

Neither of the owners have a rcc account.

Man I been using mine since day one sv3 tekin 35t handwound on 2s 45c no issues yet and I've driven this rig

Just a few posts up.

[rockspider]

Sure setting the correct mesh and backlash on those gears can help a lot, but given the small size of those gears, I'd like to have HD R&P anyway...
I've put my buying desire on hold for the moment.

[scalecrawlin]

Add me to the list of broken gears! I am only running a 35 turn Atomik ($11.00 motor) My rig hasn't even seen the dirt yet at all and it broke while crawling over my son's croc shoe. Wow maybe they should have made these gears out of plastic instead of this pot metal they used. I bet they would hold up better LOL! Also the manual states to put thread lock on the m3x8 screw that holds the gear to the shaft....well I stripped the screw out trying to get the dang thing out, so I had to drill it out and doing that it ruined my drive yoke! Are most people breaking the front gear or rear gear? Mine was the front.
