The next time the carb is apart I would be glad to take some pictures, but in the meantime if you start a thread in the 57 to 69 Sportster section I am sure you will get all the info you need.

It's getting serious now. Both feet on the ground! It's time to slot the engine in place, but one small delay, I have to build it first. Engine build next!

When I tore the engine down years ago I found the pinion shaft was very worn, so new Jim's pinion was purchased.

Image

Having a new pinion shaft separate from the flywheel makes it dead simple to do the plug fit method of sizing the roller bearings.

Image

I had cleaned up the journal with a line bore lap way back when and had forgotten how far I had taken the lapping. Since I have all the oversize rollers on hand I used the plug fit to find out. Plug fit was at .0004 over standard so the bearing journal was still nominal. Standard rollers going back in.

Image

Next step - build a flywheel.

Flywheels together. Truing has begun. Now that rough true is complete the dial indicators will come out.

Hi Dave - Where did you source your Allstate Dirtman tires? Their website doesn't seem to show any purchase/ordering information. Thanks for any info you might have.

I got them from Lowbrow a couple years ago, but they don't carry them now it seems. They do have the Bates line and they look quite close.

I was tested by this set of flywheels. Normally I can true a set of wheels over a period of a few hours at the most. This set just wouldn't come into true. After too long fighting with it I decided to take the wheels apart and here is what I found. A significant portion of the crank pin threads had cracked off and fell apart when I took the nuts off. They were torqued to spec, 150 ft lb.

Image

This was a NOS complete rod set from old Dixie Distributing stock; rods, crank pin, nuts, rollers and cages. My assumption is that there was an error made at heat treat and they were made too hard and not tempered properly.

I purchased a new USA made Jim's crank pin and Jim's crank pin nuts. I had to lap the rod races since the Jim's crank pin was ground .001 larger than the Dixie pin. The wheels were much easier to true this time. I am thinking that the Dixie pin may have not had the taper ground exactly right either, making it impossible to true correctly.

I was happy as hell to move beyond the flywheels finally!
