 ===== Front Wheel Bearing Lock Nut Retainer =====
+A number of 1972 Super Glide and Sportster models were produced with the front wheel bearing lock ring (11035) installed backwards which can result in the front wheel to be loose or the bearing (9009) to lock up. The retaining ring is flat on one side and beveled on the other and used on wheel hubs from 1964-1972 to hold the bearing in the hub. Affected Sportster VINs were (3A or 4A) 39624H2 to 50531H2. Some of the motorcycles affected were caught and corrected at the factory and affected dealers were notified also. But in case some of these motorcycles were already sold to customers, the MoCo treated it as a safety defect in accordance with the National Motor Vehicle Safety laws. The dealers were to remove all suspect front wheels and inspect the retaining ring and bearing for damages at a reimbursed cost of $2.10 for labor and handling each and reinstall the retainer with the flat side toward the bearing (beveled side out). ((HD Service Bulletin #638 dated August 14, 1972 pg OC-407))

 ===== Rear Wheel Rim, Tire and Tube Flap =====
   * From September 20, 1966 through the 1969 model season, a rubber tube flap (43148-67) was installed on the rear (steel wheel only) of Sportsters before the tube and tire were installed. ((HD Service Bulletin #545A dated June 7, 1968 as revised in April of 1970 pg OC-230))
   * This new tube flap was also recommended as a retro fit to earlier model Sportsters. Consequently, the ’59-’69 FSM includes the installation of this flap with no specification of year model used on. However, this new flap did not make it into the 57-67 Parts Catalog or the 68 Supplement Catalog.  It first appeared in the 1969 supplement Catalog.

   - Clamp the axle in a vise vertically, threaded end up.

   - Once you have a little end play, torque the axle nut to 60ft/lbs and check end play again. Use shims to get your desired end play (shown in the FSM).
   - When you have the correct end play you can either: use with the spacer and shims that you have in there, or have a single spacer machined to the combined length of the spacer and shims.

It goes in between the right side bearings in the hub, and pushes/holds the outer bearing flush with the hub where it goes up against the inside of the brake backing plate. Others have also said it is OK to use a second one in between the backing pate and the outer bearing if you need a little clearance so the backing plate wont rub, but if you need more than those 2, you should look inside your hub for issues...

+===== Tapered Bead Rims =====
+The "special" tapered wheels that were paired to the "special" tapered bead rims were known as "C-section" rims. ((HD Service Bulletin #597)) \\
+"C-section" rims can be positively identified after the tire is removed from the rim by the part numbers stamped in rim. \\
+The taper was at the 'normally flat' area from the inside bead seat corner and the shelf edge at the drop towards the drop center. \\
+The metal 'shelf' tapered toward the center with a safety hump just before the drop down. \\
+This was a "special package" buy from Goodyear with the rim included since you couldn't buy the tires to properly fit the rims anywhere else but them.
+  * "C-section" Rim Part#s for "High Ground Clearance" Sportsters:
+    * Steel Rims:
+      * Front (43003-70) 19 x 2.50C
+      * Rear (43004-70) 18 x 2.50C
+    * Aluminum Rims:
+      * Front (43010-70) 2.50C-19
+      * Rear (43008-70) 2.50C-18
+Standard low clearance models did not have the "special" rims and use standard tires. \\
+  * Other notes:

 ===== Tire Fitment Chart =====
   * HD issued a bulletin in June of 1978 regarding tire fitment on 1000cc, 1200cc and 1340CC models for proper matching of tires and rims. ((HD Service Bulletin #M731 dated June 20, 1978))
     * "For the personal safety of the motorcycle rider, tires and inner tubes must be correctly matched to the wheel rims.  Mismatching tires, tubes and rims may result in damage to the tire bead during mounting or may allow the tire to slip on the rim damaging the tube and causing rapid tire deflation.  In addition, using tires and tubes other than those specified may adversely affect motorcycle stability".

+===== Tapered Bead Tires =====
+|mystique surrounding the use of taper based tires/ rims apparently centered around 18" and 19" rear tires.  ((http://www.jockeyjournal.com/forum/archive/index.php/t-22085.html))
+Starting in 1970, Harley Davidson partnered with Goodyear for new "special" tires and rims for standard "high ground clearance" Sportster models. ((HD Service Bulletin #597)) \\
-==== Service Updates ====
+The tires are identified on the sidewall as (front - 3.75 x 19 Sport Rib and rear - 4.25 x 18 All Traction) \\
+The MoCo has written that these tires must be used exclusively for replacement on the special "C-secton" rims. \\
-  * **Tapered bead rims**, both steel and aluminum, were used on 70's model Sportsters. The taper was at the 'normally flat' area from the inside bead seat corner and the shelf edge at the drop towards the drop center. The metal 'shelf' tapered toward the center with a safety hump just before the drop down. It looks like it was a 'special package' buy from Goodyear with the rim included since you couldn't buy the tires to properly fit the rims anywhere else but them. ((HD Service School service bulletin #597))
+These rims have a special tapered bead seat with a safety hump at the top of the center drop. \\
-    * The special "C-Section" rims are identified by the following numbers stamped inside the rim:
+By design, standard tires such as Goodyear 3.50 x 18, 4.00 x 18 or 3.25/3.50 x 19 sizes will not fit correctly on these rims and are an unsafe replacement. \\
-      * Steel rims: Front 43003-70/19 x 2.50C, Back 43004-70/18 x 2.50C ((HD Service School service bulletin #597))
-      * Aluminum rims: Front 43010-70/2.50C-19, Back 43008-70/2.50C-18 ((HD Service School service bulletin #597))
