Nerf bar bind

[Mrdavid78]

If i have a left side nerf bar that binds a tad, will that bind up my chassis ?? Nemesis dirt oval.

Yes, they need to move freely

 

[Mrdavid78]

So they shouldnt have to be persuaded in at all ??

I put my nerf bars in and didn’t even tighten the bolts. I just put a locknut on it and tightened it a tad bit and that’s all. I need to loosen up my front bumper cuz it is tight

That would be correct.

They bend pretty easily. Stick the bent end into its spud and push or tug as needed.

Yes, the front doghouse should slide in and out freely.
I take the nerf bar bushings and throw them away.
I pin nerf bars no bolts

Sorry to hijack thread but my bumper is extremely tight on my chassis. After I got it powder coated it was extremely tough to get front bumper on. What can I do to fix that. It may help my chassis

 

[mike97760]

Sand the powder coat off so that its free. Clean up the insides of the frame tubes where the bumper slides in. Small diameter flap wheel will clean it up.

As mentioned clean the receiver tube and the bumper ends, grease and reinstall

Nerfs and bumpers should flop and not bind at all.
As mentioned, they are easily "persuaded" ie bent to fit loosely.

It also doesn't hurt to pull the body and bumpers occasionally to check them (clean, etc.) Be careful of using grease in the spuds, as grease collects dust/dirt. Just keep everything clean and free and they won't become a problem.

Grease in the nerfs, no.
Grease front bumper, yes it helps keep keep the dirt out

Should I tighten front bumper down or just put a bolt and lock nut on it and just tighten a tad?

Just snug up the lock nut, and if the bolt fits tight in the hole, open it up a little

Anything tight will affect the handling and setup. Same thing for any bolt including floor panels. Not uncommon on sprint karts to leave many bolts loose.
