Tamiya King Hauler V3 with 3 speed tranny

thingiverse

this is the absolute last upgrade to this truck i might make miner changes if i think i can make a part better but right now there is absolutely nothing on this truck i can think can be made better to upgrade your v2 to v3 these are the only parts to reprint required parts for upgrade to 3 speed tranny drive shaft A new frame required linkage set new hubs set 3 speed tranny required tranny shifter parts required servo arms 2 tank and tool box spacers required these will no longer be able to just bolt to the frame optional diff center gear and new axles and spacers this new upgrade centers the diffs shafts and gear esp front where one side was shorter than the because of differant spacers on both sides when installing hubs now 1mm spacer on both sides of center gear installed when installing shafts these are cut out so that they will only install while putting in the axles this is required so that the axles remain the same length on both sides 2 axle washers on each front wheel shafts while installing wheels this takes out the wobble in the front wheels and hub and bearings the new innner diff gear and axles are loose do not use glue in the front diff this allows the inner axles to be pulled all the way through the bearing on the hub use glue on the rear diff center gear and axles so the axles do not come out yes i know there is a lot of play this also allows the center gear and axles to center them self in the differential this will keep them true i am considering in the next upgrade will be set screws for the axles but right now just use glue and i am sure that nobody is going to want to tear the thing apart again to just use a couple of set screws changes taken off some of the wheel tread now understand why tamiya has no tread with this gear box if the truck is blocked by a wall or chair and wheels stop on carpet this gear box will start skiping gears and posably damage the whole gear box hopbuly with less tread the wheels will just spin on carpet the windows frames are just frames now to glue thin clear plastic for windows the best is to use blister packs i used to save every blister pack i had to cut to get to the product for just this reason this stuff is perfict for g scale building windows and for cars a and truck windows added the tamiya 3 speed tranny i have made a interior roof light to light up the interrior and driver i have used the status light but i think it probably should be wired to the 2 outside roof marker lights keeping the status light by the power switch changed front end stearing and added second servo for tranny moved front end stearing put connecting rod in back of stearing shortened stearing arms matching tamiya arms travel changed repaired offset of wheels axles caused by not same spacers now 1mm spacer goes on both ends of center gear making the front axles fit better into hubs removed horn and roof marker lights to be printed upright or on a sla printer for cleaner printing have kept the old cab and roof lights if you are unable to properly print lights and horns split the exaust stacks so that all chrome parts can be printed on a sla printer again for cleaner printing so that they can be chromed with a somther surface added 3 holes in rims for 2mm screws and bolts to line up and screw rims together
