4-Tec conversion

I have tons of sag on that belt. I can easily get it on and off by hand too. Not sure how you set the tension, I guess by altering the height of the front transfer shaft...

I need new belts, but I intend to wear these out first!

Wow, I thought mine was loose with ~1/2" of sag! There's no way I can get it off without removing the end plate from a pulley.

Yeah, you adjust tension by shimming under the 4 screws holding down the front transfer shaft. Not very effective though because by the time you get the long belt right, the front is too tight. I'd rather see a simple spring-loaded idler riding on a bearing.

I was going to make one for it... I do need new belts, and the 2.5 and 3.3 use different pulleys and different belts too. I think my other belt is the wrong one (so is my luck). My front belt is just right with no shims, so I guess that I need a new center belt...

I may give the one I have a try...

The only difference between the 2.5 and 3.3 belts is the front and rear belts. The center is the same since it uses the same pulley size. The f/r small pulley went from 15T to 20T IIRC, so a larger belt is necessary.

You might want to just brace the chassis. I know that the belt had a ton of play on mine until I braced the chassis. If you push down on the center belt, you can actually see the chassis flexing.

This is true, I am thinking about the front and rear belts. I will rig some sort of brace up, I have a few ideas in my head, but will wait for the neu cells to come in before I do anything.

On another note, I destroyed the front belt just now... I guess I get to order a new one, or maybe check the LHS (waste of time usually). The stupid hole in the chassis at the front allowed a rock in and it jammed between the diff and the front upright/shock mount. I may add a hole in the front to allow debris out... Bad design not having a sealed front and rear belt setup... Maybe I can make something. I was thinking about a new chassis for the beast...

at least when you hit a car tire at 50mph you won't lose much! HA!

even at that, this is a perfect example of a street BASHER> cant get any more ghetto fabbed thant his thing.

looks like a ton of fun man.

I stuck a stop sign post at about 50mph yesterday, backwards... The body looks a bit rough, but it is still in one piece!!! My rear body mount/shock tower is a bit creased, but still works like new, luckily it is an rpm part.

I hit a big full trash can yesterday and it almost fell over. I hit is so hard the center belt came off... I will say that this is the strongest TC I have ever bashed...

[mjderstine]

thats def saying something, i usually find the less race oriented the TC the stronger, bash away man.

where is the backflip?

Oooh, that sucks. Changing the front belt is a royal PITA.

Yeah, I had the diff out last night, swapped it for a locked one that came with the car. I had to take out about a dozen screws, not as bad as a jato diff though (is anything that bad?)...

Its actually easy to change a jato diff.. You know you only have to take the back out right? Just take the back out where the battery box is its the 2 first screws on the bottom and then the 4 on the back.

Yeah, I guess I meant the tranny when the idler and blows up. Still a pain compared to an electric rustler tranny.

Thanks Ryan, I can appreciate that remark as I am quite gangster myself.

[Takedown]

I figured you'd say something like that if I mentioned 'baller'.
