  • '29 Four motor work questions

    A fellow named Juris Ramba in Latvia repaired a crankcase half for my '29 Scout, and Juris is now restoring a 1929 Indian Four. He needs some technical questions answered, here's part of his message to me:

    "OUR 1929 INDIAN 4 ENGINE AND TRANSMISSION CASE NEEDS LINE BORING. WE HAVE THE BORING MACHINES AND EXPERIENCE IN LINE BORING, BUT THIS INDIAN CASE HAS CERTAIN NUANCES AND I WOULD LIKE TO FIND OUT AS MUCH AS POSSIBLE BEFORE STARTING THE LINE BORING OPERATION. ALSO THE SAME WITH INDIAN 4 RODS. WE HAVE GOT THE SPECIAL ALUMINIUM TIN MATERIAL B 850 FROM WHICH WE ARE GOING TO MACHINE THE INSERT BEARINGS. I GOT THE BASIC SPECIFICATIONS FOR THAT, BUT I AM SHORT OF THE SPECIFIC INFORMATION ON SPLITTING/CUTTING THE BEARINGS IN HALF BEFORE FITTING THEM AND BORING IN A SPECIAL ROD BORING MACHINE THAT WE HAVE."

    If you have the expertise to help him, or know of someone willing to share their knowledge, then send me a message on this forum and I'll pass along his contact info, or vice versa! Thanks!

      Howdy sir,

      Mark Hill. Though much of his reputation is now based on Hendersons, he has an extensive background with Indians having built and ridden a 440 on early Cannon Balls fitted with case squirters as used in Porsche 911 engines. Much knowledge of line boring via his Burco machine.
