SCX10III Kit clicking noise after placing the pins correctly

[westerlycarrot9]

Greetings everyone,

This thread has probably been opened a thousand times judging by the amount of videos that exist on Youtube on how to fix it. I got the original Wrangler kit about a week ago and like many other owners before me i got the famous clicking noise from the tranmission whenever it is underload, comes in contact with an obstacle etc.

In fact when i drive straight there is no clicking sound however when i turn either left or right it starts. To my surprise when i drive backwards it doesn't click!

I have isolated the transmission from the drive shafts to make sure that it comes from it and it does. I have placed the gear pins into the correct gear slots and i still get the clicking sound. Any other ideas? Maybe put some more grease all over the transmission and shafts? Maybe adjust the pinion gear of the motor?

Thanks in advance.

It's been awhile since I looked into this but if I remember correctly one of the gears in the transmission is easily mounted backwards. One of the small gears has pin slots on both sides and if it's in the wrong way it makes a clicking sound.

I vaguely remember this as well. One side has a rounded slot for the pins, the other is squared off..... I think....

@OSRC & @soze Did you do this on your rigs?

I remember checking to make sure I had the correct side, and either it was correct or I corrected it. It was several years ago though.

OSRC is right. I had mine in backwards, had clicking, and flipped it over to fix t his. There's a video on YouTube explaining it.

Yup had same issue. Flip the trans gear. - I've also seen people put the wrong pin in the input shaft (don't ask, I don't know either). Pin should slide in, but should NOT wiggle in the input shaft.

This videos shows a different fix, but it's the same gear. One side is cut more squarely than the other and fits tighter.

Thanks for your answers guys. I actually opened the transmission again and tried placing the pins to the opposite slot of the gears although i was pretty sure i placed them right the last time i opened it. Turns out the clicking went mostly away this time around but i guess that the grease that i put onto the pins themselves also helped.

Apologies for reviving an old thread but this is relevant to my situation as the very same thing happened to me yesterday, when I swapped gears in my Gladiator transmission, to bring it to 1.7:1 as I was swapping portals for straight axles. It all works nicely but I hear that click.

Would you happen to remember if it's the 'small' or 'big' gear, the one closer to or further from the slipper clutch?

I'll post pics of my swap when I am done so we can add to this database. In their current position, they DO click exactly as you wrote. I am guessing I drew the short straw

Thanks in advance!

Small gear - AXI232033 in the pic above. I think it's the only one slotted on both sides.

Thank you!

OK, this is quite fun: both of my gears are slotted on both sides, and the slots look identical...

Re-reading the thread, it also seems some people mention the small gear, while others mention the big gear. I am getting confused

However, I just followed what OSRC said and swapped the small gear. I noticed that, in my tests, the bigger gear would slack the same way on either side, but the smaller gear, when held alone against its clutch and rotated, did exhibit some of those clicks I was hearing when assembled. I flipped it the other way around, pushed it nicely into the retaining pin again (I heard a "CLICK!" this time, not sure I had pushed it at all the other time... wondering if that's the cause, more than the side I used), and tested some rotation... I could not hear the clicking. So I kept the big gear the way it was, flipped the small one, as OSRC wrote, and assembled it again, after greasing things nicely and tightening the slipper 'clutch' nut.

It all runs very smoothly, and I cannot hear the clicking, just the normal noise gears make... but not the weird, very-pointy click. We'll see... updates coming soon.

UPDATE:
Solved. Super smooth, no issues so far when fully rebuilt. Thanks everyone for the help, once again!
