====== IH: Wheels, Brakes & Tires ======

===== 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.
  * This is a wider rubber piece than the standard rim strip that extended from bead to bead and all the way around the rim. It rode between the tube and the tire at the bead area and between the tube and the rim at the spoke areas. This change was made as a safety precaution to provide greater protection against tube wear caused by the tire bead edge rubbing on the tube at this point under heavy operating conditions such as off rode or maximum accel / braking conditions.
  * The use this rubber flap was ended with the 1969 year models with the introduction of the 1970 year model taper beaded rims and tires. 

===== Wheel Spokes =====

==== 1979 ====

The procedure for lacing 16 inch wheels changed to make them easier to lace in production. The relationship of the spoke flanges on the wheel hubs changed to match the new lacing pattern. Rims, spokes and nipples did not change. ((HD Service Bulletin #M-738 dated October 17, 1978))

  * With the new style wheels:
        * The inner spoke pairs on opposite sides of the wheel cross each other. The outer spokes on opposite sides of the wheel cross each other.
        * Pick any outside spoke hole and sight straight across the hub. The first spoke hole to the right of the line of sight is an outside spoke hole.
    
  * With the old style wheels:
        * The inner spokes on both sides of the wheel angle in the same direction. All outer spokes angle in the opposite direction.
        * Pick any outside spoke hole and sight straight across the hub. The first spoke hole to the right of the line of sight is an inside spoke hole.

===== Measuring / Sizing Wheel Hub Spacers =====

  * If your unsure of which hub spacer you need , the best way to find out is to mock up your wheel / hub and do some measuring: ((rivethog of the XLFORUM http://xlforum.net/forums/showthread.php?t=1638639&page=2)) \\ Wheel bearing endplay should be.004"-.018" with the axle nut torqued to 60-70 ft/lbs. ((1979-1985 Sportster FSM pgs 2-9,  2-15))
  - Install outer races into the hub, make sure they're fully seated. Don't install any seals yet.
  - Clamp the axle in a vise vertically, threaded end up.
  - Put axle spacer onto axle. (doesn't really matter which one)
  - Slide 1 bearing onto the axle. (no grease or oil in the bearing)
  - Put hub/wheel onto the axle.
  - Slide bearing spacer onto the axle.
  - Slide the other cone onto the axle.
  - Put a spacer onto the axle that's long enough to reach the axle threads and still leave enough room to put the axle nut on.
  - Put the axle nut on and snug it up. (not too tight yet)
  - Lift the rim/hub and see if you have any end play. 
      - If you have too much, the spacer is too long and a shorter spacer is needed. You can try and find a shorter spacer or shorten the one you have. (a lathe is the best way to shorten it). 
      - If you don't have any play, the spacer is too short. Add shims until you get just a little play.
  - 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.

===== Right Side Bearing Spacer Washer (between the bearings) 1963-1978 =====


  * On 1963-1978 XLH/XLCH Models, a bearing spacer washer HD part #41195-63 (or V-Twin part number 44-0395 ((Icefire of the XLFORUM http://xlforum.net/forums/showthread.php?t=1533577&highlight=size+rear+wheel+spacer+washer&page=2))) is placed between the two bearings on the right hub (brake side). This spacer washer is reportedly not installed at the factory but is a service part for alignment where the aluminum back plate butts to the bearing inner race due to wear. The race will plow right into the soft back plate when the axle flexes ((Dr Dick http://xlforum.net/forums/showthread.php?t=1844782)).
    * This is not a grease shield for the bearing. The grease shield used on the brake side  →'62 was no longer in use by '63 and up models.
  * This small washer has a lip, its very thin, and is not a regular flat washer. 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" wheels that were paired to the "special" tapered bead rims were known as "C-section" rims. \\
"C-section" rims can be positively identified after the tire is removed from the rim by the part numbers stamped in rim. \\
  * "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:
    * 43005-70 steel 18" steel spool rear drum
    * 43008-70 (250 C) aluminum 18" steel spool rear drum
    * 43002-70 steel 19" '64-72 style front drum
    * 43010-70 aluminum 19" '64-72 style front drum
    * 42998-74 (250 C) aluminum 19" aluminum hub front disc (made in Italy)
    * 43018-73 steel 19" aluminum hub front disc

====== 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))




===== 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". 
    * Tires:
      * Use only tube type tires with inner tubes on all Harley-Davidson wheels. Tubeless type tires will not seat properly. Protective rubber rim strips must be used on laced (wire spoke) wheels.
      * 16" (seven spoke cast) wheel requires a center valve tube (40553-78) while all other 16" wheels use a side valve tube (40550-77). Tires were interchangeable between cast and laced (wire spoke) wheels.
      * 18" tires and tubes were not interchangeable between cast and laced (wire spoke) wheels. The bead __diameter__ of the MN90-18 tire was app. 0.075" (app. the thickness of a nickel) larger than the 4.25-18T tire.
      * 19" used the same size tube for both cast and laced (wire spoke) wheels but the tires were not interchangeable. The MJ90-19 tire also had a larger bead diameter.

===== Factory Tire Information =====

  * Rim size and contour are cast or stamped into exterior surface of rim. 
  * Example: T19x2.50 CO DOT. "T" indicates the rim conforms to 'Tire and Rim Association' standards, 19 is the nominal diameter of the rim in inches measured at the bead center diameter, 2.5 is the width of the bead seat measured in inches, CO designates the rim contour, DOT means the rim meets Dept. of Motor Vehicle Standards.  ((1979-1985 HD Sportster FSM))

==== Service Updates ====

  * **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))
    * The special "C-Section" rims are identified by the following numbers stamped inside the rim: 
      * 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))
