Default Smoother Bearings??

Ive bullt my car, just waiting for motor and bits to be delivered.

I just wanted know why when i push my car or spin the wheel, they dont spin as long or as fast as people at my track.

Is it because they havent been run in or is it summit else.

Ive heard that people soak them in WD40 over night, does this help.

Thanks

do you mean with the motor in it. Some motors have more resistance (especially if its new) than others.

most cars when new come with the bearings they have been oiled with a thick grease that lasts for ages but increrases resistance so what i do is remove the sheilds ech side f the bearing then squirt them out with motor spray then put 1 side back on ad 2-3 drops of bearing lube or tri flow put the outher sheild on and the bearings will have almost no resistance.

but wait if u have alot of money to spend and don't mind replaceing your bearings reguraly, clean them out but dont oil them your car will again have slighly less drag although i dont reccomend it.


hope this helps

Spray the bearings out with motor spray, and spin them with your finger...they should spin for several seconds. Oil them with a light lube and put them back in your car. If you really want them free pull the inside shields off (ones that dont have contact with the open air) and do the same process. You'll have a little bit less drag. But by doing either your bearings will be much more free.

If you don't oil them the'll get flat spot's from fine dust and you'll have to buy new one's........ make sure the wheel nut's are'nt to tight back them off a hair and this should free up the bearings.. have fun when you get the rest of your gear.....

A new car will need time to get free. Belt driven cars especialy need time to 'stretch' the belts. This is normal. Time to stretch belts will vary on the motor you run in it etc.....
Even the bearings need a bit of time realy. but not much change in bearings will be seen. But the belts, there is a distinct difference after the first few times the car is run. just be patient

i wouldn't spray out the grease from bearings, they are there for a reason. to reduce friciton.

if you replace the grease with oil, then invariably the balls will grind against the cages.
