| TRX 4 Chassis New Build
Well I finally opened the box and got the manual out to read it first. Page 4 Transmission; Looking at post here and some RTR's; Bearing grease? I am not to fond of hearing that some parts have had little to no grease. Can the bearing seals be removed to add grease into them? I got a tub of Vanquish HP Synthetic grease but now I am wondering if marine grease would be better as some of you have posted? If marine grease any brand better? |

I use red and tacky from Lucas on my rigs. I don't drive through water though. Works really good after inspections Sent from my SM-N950U using Tapatalk |

The bearings can be opened, though they are greased fine from the factory. They are well sealed too, took mine apart a while ago and they were perfectly clean inside. I wouldn't worry about them. I use Red and Tacky as well, just a light coat on all gear mating surfaces. Almost any grease will do really, something thicker is better as it doesn't get flung off as easily. The green TRX grease that comes with the kit isn't bad at all to be honest. |

Thanks Just trying to figure out if there are any weak spots while building this chassis kit, Kind of do it now rather then later. Figured if they could be unsealed then packed with grease, it would at least get the bearings to last longer. |

X3 on Red N Tacky. It stays on he gears pretty good unlike some other grease I’ve used. _________________ 79 F150 SCX10 ii TRXWalker |

That's extremely overpriced. You can get something similar that will do the same job for less than $10. There's plenty if you look around | |

I was just wondering if there were any problems that's all. That optima in my avatar when I got the new rear trany case I had to use auto silicon sealer when mating that cases together as they were kind of warped?? Just thought maybe I might have to do the same thing on the trx4 I guess that would not hurt none here keeping water out is a good thing I think. |

The only aluminum upgrade I made in the trans motor area was an aluminum motor/trans mount. RZXYL Aluminum Alloy Motor Mount Heat Sink for Traxxas TRX4 RC Crawler Car Upgrades Parts (Black) https://www.amazon.com/dp/B081YHY796...ing=UTF8&psc=1 With the plastic stock motor mount, my motor moved a lot when mounted to the trans. This supports it very well. The motor is rock solid. I bought a GRC originally and that was $$$$$ compared to the one I linked. I picked up the amazon one as a spare. They’re identical. |

If I may I have a question On the transmission build when you are done on the spur gear is there normally about a quarter turn of free play (spin) ? Then there is an optional part listed, "Traxxas 8249 Slipper eliminator plate" is this a better setup? No slipper clutch? |

Just be wary that if you are driving and get a wheel jammed in rocks etc, don't try to force it to drive or other parts will get damaged seen as the clutch can no longer slip. The stock motor delivers a lot of torque. | |

The 1/4 turn in the transmission is normal. This allows the gears sufficient play to allow for shifting.

Well the Goody bags all got here I know, I know, Just shut up and build the thing! Temptation ?? Who can resist? All the new cool parts and all that. I got two bodies both axial, the jeep Cherokee and the chevy pickup I am going with the Cherokee for my first build as for staying stock and me wanting to just get one rock crawler and not have to mod nothing! Well that went out the door from reading the post here! So it is all your fault ;) Instead of brass weights I went with yeah axle kit with the skid plates and the aluminum parts for the axles An aluminum motor mount? and the v-8 engine cover with fan The rest of the parts are for the body, not sure what else I will need? But a good light kit I do need to get! Been kind of busy trying to clean up around here from the Ice storm we had! So SO many branches and trees have fallen here it would take a long time to clear everything by hand, So thing are slow in my build. Then I have the Wife's flower seeds to plant and germinate so she can have flower pots that the chipmunks can dig up to make her mad! Then turn and with blazing eye's say Can't you do something about them dam things! |

Ok I got a problem on my build I got a savox steering servo a SA-1230SA one it does not line up with the install holes length wise second the wire to the receiver is short by about8 inches! Do I get an extension cable? or get an extension cable an cut and solder them then use heat shrink to seal the soldered wires? Next were do or can I mount the castle Mamba X ESC? or just find a spot where it will fit? |

I've got the same savox servo fitted to both a standard trx4 and also one with a lift kit and the modified servo mount that comes with the kit. They do fit, just needs a bit of tweaking. From memory, I didn't use the bolts which came with the servo, seemed soft and started to strip the head easily. The standard trx4 was fairly simple, just need to get all 4 screws started in the holes before attempting to screw them in fully. Help them to pull straight and they will work. Sometimes it helps to trim a bit of plastic off of the servo but this will void the warranty. The trx4 with the lift kit took quite a bit of messing as I altered the mount to provide more clearance for the axle under suspension compression. Regarding the wires, I just bought an extension lead. I think it was 7 inches. The plug in type are easier, no soldering required. Last edited by JonnyUK; 04-13-2021 at 04:45 AM. | |

I’ve had to file out the passenger side mounting holes of both aftermarket servos so far. I “think” this is what you are referring to. I I then screwed it in using the stock holes in the servo mount. I’ve had no issues. A common occurrence I believe. I’m pretty sure Savox servos require an extension. I put the mamba x on the drivers side slider. It’s where the stock esc was.
