Seal and Clutch Assembly
The exploded diagram of the drive train shows the correct sequence of clutch
washers. In the WKPP clutch, there are three matched sets and the one facing
down at the ring on the bottom. With the Mako clutch there are four sets plus the
one facing down.
The seal is easy to replace. Remove it with channel locks, remove the inner
donut with an o-ring pick. The snap ring is under the inner donut. There must be
no play in the shaft. Check and be sure that the ring is in place. It is steel, not
stainless, since it needs to be as hard as possible. Place the new donut into the
hole without any kind of silicone or lubricant. Spray the bell side of the seal with
lubricant. Put a drop of motor oil on the donut. Slide the bell down and then press
the rubber ring down all around with a flat bladed screwdriver. Then add the
spring, cap and stainless snap ring. Run the motor for a couple of minutes to
break in the seal.
You do not need to take the motor out of the scooter to replace the seal.
