Pulling the Race
Cut the head off of a C-clamp and welded on locking tabs. Huck of tubing from the scrap-bin sliced lengthwise, slotted for the locking tabs with a cut and ground 1“ Hilti bolt washer welded to one end. Another hunk of refuse tubing with set-screws as a sleeve to hold it all together. |

* A piece of 4” steel channel as a base. * Two automobile connecting rods are then bolted to holes drilled in it at the right distance apart to suit whatever flywheels are being worked on. * A threaded insert was machined up so a half-inch or so bolt could be threaded threaded through, with locknuts to hold it in position. * The ends of the bolts are machined to a point same as a lathe center (60 degrees maybe?). * A magnetic dial gauge is stuck to the base to suit the job at hand. * This rig has been used to do countless numbers of 45 Flathead bottom ends, J models and big Brit singles like the Matchless wheels in the pic. * The alignment of the two center bolts is not super critical (they just provide the two points). The flywheels and shafts are a straight line between them. |

Here is a pair of adaptors to swing big fat Harley 9) flywheels in a small lathe like a 4.5“ swing Myford etc. |
Here is another way to true flywheels in a small Myford lathe that has only a 4.5” swing that won't fit Harley flywheels. Two offset pieces made from some flat half-inch thick bar and some half-inch round bar. |

Crankshaft / Flywheel Installation
Weld an extension shaft to a coupling nut, cut a piece of gas pipe the same diameter as the inner bearing race, welded a stud to the side of tube so it will stop the tube from spinning while tightening and eliminating the possibility of any metal shavings getting into the bearing while tightening the nut. Make sure the extension is long enough that you can grind a flat on each side of it so you can hold it with a wrench tightening the puller nut 11) |
