VN900 Front Pulley Maintenance
When I buy a bike, I usually pull it apart to a great deal, and fix what the factory and the dealership forgot, so that my ride will be to a "known" mechanical standard to me.
I bought a 2016 VN900CFG in Oct 16, and now with 1500mi on it I am just now getting around to "exploring" some factory/dealership maintenance on it.
One thing I wanted to check was the grease, or lack of it on the drive pulley, that will prevent it, and the counter shaft from wearing out. So, after obtaining a Kawasaki 57001-1672 rotor holder off ebay to hold the pulley, I was all set.
See pictures below.
From the factory there was but a drop of moly on the nut. Yes, exactly a drop. The countershaft was dry with nothing on it as was the inside of the pulley splines. Yes, they are cleaned in the pictures below, but looked exactly the same as when I took them apart. If this condition were allowed to exist, shaft and pulley wear are guaranteed to happen. I advise you, or your mechanic, to have a look at your pulley during your next maintenance stop.
I used a new nut and washer. Coated them both liberally with Honda-77 Moly. Also applied Moly to the pulley splines and counter shaft splines as to prevent "fretting" there. Same drill I do to the drive splines of my shaft-drive motorcycle. For reference, ALL drive splines on any motorcycle that are not lubed by gear oil or engine oil should have Moly applied to them to prevent wear. Sorry I don't have any pictures of what these parts look like after I applied the grease to them. My hands were dirty. Just imagine a very liberal amount.
During belt adjustment, there is 28 1/2 inches of span from the front pulley to the rear pulley at the bottom. The mid-point @ about 14" is right in front of the rear frame crossbar, exactly where Kawasaki tells you to place the spring gauge. The belt deflection inspection window is 6" forward of the rear pulley. When adjusting the belt, @ 10lbs, I had 9mm deflection at mid-point and 4mm deflection at the inspection window. Going to try this awhile as it is within factory spec and I have not had any problems so far.
