[@Mr.Titanium1911]

Thinking of getting the USA-1 and doing research before committing. Great video.. very informative. Good work ethic too👌🏻

Hello I have a question the grub screw that holds the sprocket on I accidentally stripped and I'm not sure what size it is do you know what size grub screw that is the one that goes in the sprocket with a chain around it thank you

Great video I took my transmission apart and done what you said from the other video I had a bad 1st gear one way after the part arrived I went through it again and man truck shifts great and is a ton of fun be looking for you to do your gear upgrade appreciate it

[@TurokRC]

Glad to hear you've got yours working and that the video was helpful! I'm itching to do the metal gear upgrade soon, will be sure to post a video on it

[@Dabber422]

Thank you.....

I’m confused, I thought the taller/larger diameter gear would be 3rd gear?

[@rc-jatodaniel]

No the taller the spur gear, smaller clutch bell gear, more power less speed and vice versa.

[@Nitrotrician81]

@@rc-jatodaniel Oh ok I gotcha!

Are the "made-in-Japan" replacement transmission parts of higher quality than the "made-in-China" original parts? I notice my USA-1 Box says "made in China," whereas the replacement transmission parts (gears, cams, and shaft) are all made in Japan.

[@OrcaBoat3]

At 5:17 in the video, you point out the shim in between the two cams. However, according to Page 8 (step 7) of the Kyosho build-manual, there is NO shim. This is not the first place where I saw a shim installed where the manual did not call for one. On my truck, between the clutch bell and the clutch shoes, I found TWO shims, where the manual only calls for one. It was causing my clutch bell to jam up. Once I removed the extra shim, my clutch bell freed up. Hmmmm...

Hello sir, i’m really interested in buying that kyosho usa 1 nitro that you’ve already fixed the transmission problem. If u interested in selling too please let me know, and we can have a chat. Thx😊🙏🏽

[@kennybowers7607]

I knew you wouldn't let me down thank you now I can pull mine a part get it all ready to go so I can start breaking it in.

[@TurokRC]

Glad it helped! It's a fantastic truck and easy to work on

[@allenpatterson3504]

Great video on the maintenance of the transmission I did the same thing and my Usa 1 is working great

[@TurokRC]

Glad you liked it - this video was requested by many - hopefully it helps them!

[@xKmotx]

Come on man, charge your camera battery! 🤣 Seriously, this is a great video! Nice to see a hands on, step by step tutorial.

[@TurokRC]

Haha, yeah I'm due to get a new camera. Just using a phone at the moment! Glad you liked the video!

[@bigripper2048]

one thing i just help but notice as @Turok goes through this maintenance routine is just how scarred and "grooved" the appearance of the main shaft is, it has to be the weakest link in this design, and i think kyosho really dropped the ball by not making it a premium hardened part

[@TurokRC]

I actually filed my shaft down, hence the marks. I had to do the same to my first shaft since the failed needle bearings left grooves which I filed away. It worked flawlessly after...so I did the same on the new one. Kyosho did send out some different hardened shafts but I haven't had to use them yet

[@stevevillanueva3037]

Awesome vid thanks for the help!!

[@philipsalamone8541]

Your gears slide off nice compared to mine. Mine were literally seized. That shaft has a bunch of burrs

[@TurokRC]

I had lubed the trans prior to this service. Also my shaft looks that way because I filed it gently as I did my last one, the shaft coating was rough from factory which may have cause the seize

[@redbandit8086]

Did you swap the bushings over from the gears or just the 1 bearing from third

[@TurokRC]

I didn't swap any bushings on this one

[@grandmasteryoda8588]

Hey turok I have a question so do I turn clock wise to shift earlier and counter clockwise to shift sooner?

[@TurokRC]

Clockwise would be later shift, counter for sooner

[@danieldelahaye8502]

Nice video 👍
