So got my mbs pro 90 out this afternoon in a hay field. from lack of experience the board did many rolls and flips in the dirt. When I got my board all 4 lugs were loose so I tightened them up till they stopped with a wrench. Everything seemed fine at the time, but now three of the wheels won't keep rolling if I give them a spin. The one just keeps on spinning but the rest make about half a turn and stop. Was I wrong to tighten the lugs right up or did I over tighten them?? Also thinking that there is dirt in the bearings but wouldn't think that there would be much in there from a first ride that was about 60 meters long. If anyone could shed some light on this I would be forever thankful.

Overtightened lugs.

Bearings are sealed, they won't get dirty from a bit of using the board in the elements it's designed to be used in.

Just make sure to check truck-to-board bolts as well, those often get loose....

Okay so I loosened them off to the point where they spin freely and now the center part of the bearing spins on the truck shaft is that too loose??? Tried to find info online but none to be found pertaining to mounting wheels on trucks.

I was told to tighten them till they stop then back them off a half rotation.

shaggs don't worry so much :D as long as bearings ain't seized they're working.

Dunno about the board but the general thing with wheels and bearings is that the nut should tighten down onto the center of the bearing and nothing else ... is there a little washer or something missing? Nuts on upside down?

yeah so I backed the bolts off about 3/4 turn and they spin fine. A little stiff but they spin bout 5 turns till they stop so gonna leave it there. If the bearings go on me from being over tightened in the first place then they are cheap enough to replace. Thanks again guys!!!

you can always go with the heavy duty mechanics torque code. Tighten bolt till it snaps and back off 1/4 turn...lol

Yeah I'm an expert at that, Wolf ... ask me about the time I broke off an axle clamp bolt on the bike and spent 3 hours twisting the stump out, nanometer by nanometer :ticking:

Hey Kam, tell me about the time you broke off an axle clamp bolt on the bike and spent 3 hours twisting the stump out, nanometer by nanometer... :bouncy:

end hijack-couldn't resist...

Working nanometer by nanometer, it took me three hours to get the stump out
