Roller bearing (28x42x08mm) -CIF HQ- (used for drive shaft Vespa VNA, VNB, Super (VNC till No 024899, VBC till No 70199), GT125 (till No 60899), VBA, VBB, GL150 (VLA1T), Sprint150 (till No 73899))

To install, it is best to place the cold bearing (overnight in the freezer) in the housing, which has been carefully heated with a blowtorch. Depending on the fit, first find a suitable driver that rests on the outer ring.
Once the bearing is seated, insert the lightly oiled shaft seals.
The grease packing for the bearing should consist of appropriate high-pressure grease. Pack in enough so that the rollers are just visible, but at the same time there is room for the grease when it expands.
Too much or incorrect grease can be pressed out of the oil seals when the engine is hot.
