Ironhead Rear / front hub inner bearing spacer lengths - Help!

[panama86]

Hey all,
I picked up a basket case 70 XLCH that has an earlier K model conical front hub/drum. Both of these hubs came to me empty I've got all the bits except for the inner bearing spacers.

I can't for the life of me find the length of these spacers, in the manual, by searching part numbers, forums, etc. Lots of posts of people asking for the length but no responses.

The rear spacer part number is 41185-63
The front spacer part number is 43740-52

I'm in Australia and while these parts are relatively cheap to order from the US, the shipping is around $60-$80.

This may help..... possibly, to make your own spacers.

Install one side bearing and measure from inner race to the opposed bearing seat on the hub. Take into account the protrusion differrence between inner race and outer and do the math. I believe the inner race should be proud of the outer by a few thou.

easier to work with pvc pipe
install both bearings, measure inner race to inner race. cut pvc pipe about .020 longer, install and check, file off the end till you get a good fit, probably around .005 which will move each side out .0025 which should give enough clamp force for the race. then make steel spacer.

I make the spacer or cut down as needed and add shims (shovelhead) to set the endplay on the bearings.
