The rear bumper from my first nitro RC, an old T Maxx.

Today’s objective was to replace a shattered rear half shaft, of which I took no pictures for some reason, and to replace the center differential with a main shaft that has no diff because with the diff, the truck is basically FWD. Not cool.

Here’s the subject. A normal Traxxas Revo 2 speed with hop ups like steel gears, a better slipper clutch, a vented steel brake rotor and rear brakes to go along with that center diff. You need them for a center diff other wise you just have front brakes.

Here’s the T case from below with itS aluminum skid plate. You can also see the brake rotor and steering servo among other things.

You can see the brakes and the center shafts clearly once the skid plate is off.

Here’s a close up of the rear brakes and the spur gear. The rear brakes are about as simple as they get. Two fibre disks stuck between three sheet metal brake pads. When the servo pulls on the black rod just above the rotors it squeezes them together. There ya go. Same on the front, except it’s fibre pads and a three piece vented steel rotor.

Here’s what it looks like once the six screws holding the front of the case on. The output shaft is on the bottom with the diff, above that are the gears that make it a 2 speed automatic transmission. All that shifts the gears is a centrifugal clutch that pops out at a certain RPM to catch the next gear. You can adjust that by tightening a screw to apply or remove spring pressure to make the gear engage later or sooner respectively. The third is just a simple cluster gear on the input shaft.

Old center diff on the right, new beefier output shaft and diff delete on the left. (It’s actually from a kit that’s designed to remove reverse from Revos but I had lost the original parts.)

Here’s the transmission and all the parts I removed. No more rear brakes because I don’t need em and they never really.worked all that well anyways.

Bonus picture, the 0.18 cubic inch 2 stroke glow engine that provides motive power to push this thing over 70mph. It’s an OS Racing Engines 18TZ nitro engine if you’re interested in that.
