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. 1) 2) 3) 4) 5) 6) 7) 8) 9) 10) 11) 12) 13) 14) 15) 16)
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 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). 17)
The Prefix designates the duty class: LL - Lighter than Light; L - Light; LM - Light Medium; M - Medium; HM - Heavy Medium, H - Heavy 18)
Swingarm with bearing(s) and bushings.
Note: Inspect pivot shaft and swingarm bearings every 5,000 miles. Lube swingarm bearings every 10,0000 miles. 19) |

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.

Notes gathered from the XLFORUM:
Broken Pivot Bolts:
If you are replacing the bearings, it's worth reading this extensive thread about replacing the engine rubber mounts: https://www.xlforum.net/forum/sportster-motorcycle-forum/sportster-motorcycle-era-specific-and-model-specific/rubber-mount-sportster-motorcycle-talk-2004-2006/140794-check-motor-mounts-and-swing-arm-bearings-asap?t=1526368
