RG500 Clutch Upgrade Kit Installation
Place the bike on a stand (www.peglift.com) and remove the belly pan and rh lower. Drain the oil (remember the 2 drain plugs are the 14 mm and 17 mm bolts on the bottom of the motor). Loosen the clutch cable all the way on both ends. Remove the kickstart lever (if it sticks, go to AutoZone or WalMart and purchase a battery clamp puller). Remove the pinch bolt that retains the aluminum actuator arm and work it off the splines of the throwout shaft. Remove the clutch cover (you may want to carefully bend out the fairing lower support bracket that's in the way). Proceed to the following steps:
1Lay out your new Lance Gamma clutch kit components.
2This is your clutch. Note the orientation of the splines on the center pull, facing down at about 7 O'clock. This is the correct attitude for the throwout arm teeth to engage when you replace the clutch cover.
3Using a 10 mm T-handle or ratchet and socket, remove the spring bolts, springs and pressure plate.
4Bend the lock tab off of the clutch nut and remove the nut with an electric impact gun or air gun and 27 mm socket. Note photo 20 how to position a screwdriver or hand tool to prevent the inner hub from rotating when gunning off the nut. Do not use this method with a breaker bar or ratchet and socket. Only retain the hub in this manner when using a gun.
5Applying the gun without such support will allow the inner to spin rather than the nut coming loose. Put photos 20 and 5 together and you get the picture. To tighten the nut, reverse the screwdriver as in photo 19.
6Remove the inner hub and plate stack.
7Locate and remove the thin thrust washer and clutch basket.
8Remove the clutch bearing and collar with the thick thrust washer.
9Your group of parts removed should resemble this.
10Install the thick thrust washer with a coating of oil.
11Oil and install the clutch collar and bearing.
12Install the clutch basket and oiled thin thrust washer.
13Locate the piano wire clip ends on the clutch inner hub and snip off with wire cutters.
14The wire comes off the remove the three components captured by it.
16Discard the belleville washer and seat (center and right).
17Place the LG inner hub spacer onto the splines orientated so and drop onto the splines.
18Replace the steel clutch plate onto the hub after the LG spacer. Have the side worn from clutch plate wear face out as before.
19Hold the hub to prevent rotation and gun the nut on with light torque. Just a few rattles will do. Too tight just places undo stress on the thrust washers. Bend the nut lock tab.
20Not a good time to do this . This only works for taking the nut off. Look closely. There is a difference.
21Note that the new plates have 3 tabs with notches for ease of using a pick to remove the plates. Align them together in a row so you can find the notch if you need it.
22Place all the metal plates in a stack with the rolled edges face up. (One side is sharp and the other is rounded, since they were formed by stamping).
23Install the plates as shown. Start with fiber, then alternate metal, fiber metal until you run out of plates, ending with fiber.
24Install the new springs and tighten down with the 10 mm T-handle. I believe Motion Pro and Cruz Tools have these. Good stuff.
25Install the aluminum actuator arm onto the splines of the throwout shaft so that it points slightly down toward the frame rail as shown.
26If you have it on the right spline, you will have about this much thread showing here....
Make sure the oil drains have been replaced. Do not over tighten the front bolt as they strip easily. Snug is good. Add 800 cc of quality 2stroke gear oil such as Redline or Spectro 80wt. I also have found that the Valvoline VR-1 Racing 50wt (available at Auto Zone, Advance Auto, etc.) works well and is easily found.
