-===== Swingarm & Bearing ====== 
  
-The swingarm has only one bearing. It is on the right side pivot. The left side pivot, 1986-2003, uses a bushing, not a bearing. The 2004-later models, the left side pivot is incorporated in the rear rubber motor mount.+===== Rigid Mount Bikes =====

-\\+86-88 models are shown to have two bearings and 89-03 models with only one bearing in the catalogs. ​\\ 
 +However, two bearings are used in 86-03 Sportster swingarms and they are both installed on the right side pivot. ​ ((1986-1988 HD Sportster Parts Catalog 99451-88 pg 67)) ((1986-1989 HD Sportster Parts Catalog 99451-89 pg 69))  ((1986-1990 HD Sportster Parts Catalog 99451-90 pg 69)) ((1991 HD Sportster Parts Catalog 99451-91 pg 61)) ((1991-1992 HD Sportster Parts Catalog 99451-92 pg 63)) ((1993 HD Sportster Parts Catalog 99451-93 pg 63)) ((1993-1994 HD Sportster Parts Catalog 99451-94 pg 63)) ((1995 HD Sportster Parts Catalog 99451-95 pg 61)) ((1995-1996 HD Sportster Parts Catalog 99451-96 pg 65)) ((1997 HD Sportster Parts Catalog 99451-97 pg 65)) ((1998 HD Sportster Parts Catalog 99451-98 pg 67)) ((1999 HD Sportster Parts Catalog 99451-99 pg 73)) ((2000 HD Sportster Parts Catalog 99451-00A pg 73)) ((2001 HDSportster Parts Catalog 99451-01A pg 75)) ((2002 HD Sportster Parts Catalog 99451-02 pg 75)) ((2003 HD Sportster Parts Catalog 99451-03 pg 75)) \\ 
 +Both left and right sides were described as having bearings until the 2000 parts book came out correctly describing the left side as having a bushing. \\ 
 +The part number for the bearing (set) changed in 2000 from (47082-81) to (48367-98). \\ 
 +According to the pics on the [[https://​www.jwboon.com/​index2.php?​co...rtster/​Page_15|JW Boon]] website for NOS parts, even though the part number changed for the right bearing, it appears to be a place of origin change. \\ 
 +Both part numbers refer to a '​Timken LM11749'​ bearing: (47082-81 made in Poland) and (48367-98 made in USA). ((Hippysmack of the XLFORUM http://​xlforum.net/​forums/​showthread.php?​p=5790716#​post5790716)) \\ 
 +The Prefix designates the duty class: LL - Lighter than Light; L - Light; LM - Light Medium; M - Medium; HM - Heavy Medium, H - Heavy ((https://​www.motionindustries.com/​productDetail.jsp?​sku=00657537)) ​

 +For the 2004-later models, the swingarm uses a bearing in each side and the assembly is part of the motor mounting system as well. \\
 +See [[techtalk:​evo:​susp05#​rubber_mount_engine_mounts|Rubber Mount Engine Mounts]] in the Sportsterpedia for assembly including the swingarm. \\
