CRF450 Chain Rubbing On Tire - Part 2

Recommended Posts

Not to stir up more hostility, but the sag on the chain might have been a little on the tight side and it did it again!! When I lossen the axle on the right side (non Chain Side) the axle wants to slide backwards, the bolts prevent it from moving too far forward but not backward. The axle is straight, and the bearing appear within normal limits!! I'm sure under load (driving forward) this pulls the axle forward on both sides. But if the right side axle block slid backwards it would move the front of the wheel to the right side away from the chain!! WEIRD!!

when you adjust your chain tension, slide your wheel all the way forward to your adjusters, snug up the axle so that it wont slide on its own. Then use your adjusters to slowly push the axle back evenly to the right chain tesion. after adjusting, TIGHTEN the axle nut. If your axle slides back and forth, then your nut is not tight enough.

Stuff a rag on the sprocket and rotate the wheel so the chain tightens on top of it. This will keep the wheel forward while you tighten the axle nut.
