Front Drive Sprocket

Back to article View Gallery
11 of 28
The front drive sprocket should slide out of its support bearing under light pressure. I use a plastic hammer, if necessary, to lightly tap on the threaded end of the shaft. There should be little resistance. Once the shaft is free of the bearing, the slack in the chain will permit removal of the chain from the output shaft sprocket. Do not force any of these parts. The NP/NV231 is a precise, close-tolerance assembly.
