Installing Rear belt

[steel145]

I am going to be installing my new rear belt and wanted to know what position should the rear belt tensioners be set at? I heard about some people soaking them in wd40 and wanted to know what that does.

wd-40? that sounds crazy i wonder why?

I have no clue as to why you'd soak it in WD-40?! But for tension, just set the cams back till it's got a little play in it, like a fan belt on a real car but tight enough to get the job done without the belt jumping the cogs.

Some people say that it makes it looser or something, i don't believe it.

All you have to do is adjust those cams in the back, it's not that hard even if you are lazy, infact the nitro is easier to do it on than the electric (less to take apart).

Thanks for the help. I was told that the wd-40 softens up the belt.

i never used WD40 to soak my rear belt when i installed the new one.i set the tensioners so the belt had very little play,so it would have flexability because if you set the belt to tight it could cause binding and and over work the engine"when i installed my new belt i made sure the rear wheels moved freely with out binding,

If the rear belt can be deflected more than 0.25" (6mm), the belt tension cams should be rotated rearward to the next eccentric slot.


Belt Tension Adjustment

The Nitro 4 Tec has three drive belts that can stretch or become damaged over time due to normal wear. If left unadjusted the belts may start to skip over the drive pulleys, which can hinder performance and damage the belt's tooth profile. The rear belt tension is adjustable via belt tension cams in the right and left rear side plates. The rear belt in the Nitro 4-Tec transmits most of the engine's power. Because of the high loading on the rear belt, the tension should be checked every 3-4 hours (20-25 tanks of fuel) of running
