Original bearings for Indians are rarely available. Fortunately there are modern commercial equivalents for most of them. On this page you will find 2 charts correlating the original Indian bearing numbers to modern, readily available, bearings. This is not to suggest that it's a bad idea to get your Indian bearings from an Indian parts dealer: Comparison of prices from dealers to those from commercial bearing suppliers (on the VI mailing list) did show that the dealers' prices were often lower than those of the bearing houses! More bearing info will be added on this page.
 
If you have any information to add, or questions, please write me. Thanks!

Here is my list of Indian Chief bearings to commercial numbers. It was accumulated over the years and hopefully includes no obsolete numbers. I did not include suffixes as they seem to have different meanings between makers. I'm listing them as: Indian#, commercial#, where used, and (comments). I have Torrington# B810 needle bearing listed to replace Indian #39313 generator sprocket bushing in the inner primary cover. Use with CR 4911 seal. I have a number for the clutch release bearing but when I tried to order, I was told it would be special order and the price was terrible (I don't recall if there was a minimum order or not). The number is INA # 2041. It measures 1.687" ID x 2.375" OD x .562" thick. It looks like the only difference from original is both races are grooved. Someone mentioned a metric replacement that requires some modification to the clutch worm. Hope this helps someone. I believe this is an accurate listing as the numbers were gleaned from original bearings where possible, but any corrections are welcomed. The only changes I made were to add current prefixes to some of the numbers, ie: 6207 for 207, etc.  John

The Bearings in this particular file are all for 249 vertical twin Scout. I believe that they all also fit the Warrior. I believe that they all fit the single cylinder arrow , except the crank case ball bearing, which is probably different. Mike Burns

I've attached a jpg document I scanned in containing additional bearing cross-reference info for vertical twins.  I got the info from Wally Skyrman (who gave me permission to pass it along). Rob
