2t Trojan Bearing Kit
2t Trojan Bearing kit to suit LM48548 (inner) and Lm44649 (Outer). Quality bearings by NSK, Japan.
The best way to test bearings is to run your thumbnail over the bearing cylinder and cup. The cups and races should be smooth. Replace bearings with rough surfaces.
Black grease identifies bearing wear. The black discolourisation within the grease is carbon black. Carbon black is the result of worn casting.
On the other hand, brown grease is the result of water ingress. As hot hubs are immersed in cold water, the air inside the hub contracts and sucks in water.
