I finally got around to installing Colson 4" x 4.25" Gray Flat profile Hi-Tech
Performa. They have ball Bearings and a 3/8 hole. They are not sealed ball
bearings.
I forget who I told I would report to when I figured out how to make a
spacer/dirt
shield for the bearings.
I used 18-8 SS 3/8-24 2.5 length Hex cap screws. McMaster PN 92198A361
www.mcmaster.com
and 18-8 thin Nylon Insert Locknuts McMaster PN 90101A245
I needed to drill outrigger forks to 3/8 hole.
I made the spacers out of 1.25 inch aluminium bar.
Dimensions of spacer:
1.010" OD
3/8 hole through center.
Pocket .165" deep and .935 ID
I actual made the Pocket depth ~.175, and fit exact to wheels by sneaking off a
few thousands at a time.
The seal is going to keep out dirt pretty good.
Overall completed weight is probably very similar to the stock, perhaps a bit
lighter.
