And yes there is a car in the living room but that’s not what I’m going to work on. I’m going to install the bushings in the spindles and hone them to fit the kingpins. But first I have a needy cat on my lap who wants belly rubs so brief break.
OK belly rub needs satisfied, back to the blog post.
The concept is simple, the kit ships with bronze bushings that press into the spindles and have to be fitted to the kingpins, similar to how the axle bosses had to be fitted so the kingpins would go in and out of the axle. The difference here is the kingpins are locked into the axle with the grub screw while the bushings have to be honed for working clearance, the size difference is only a few thousandths of an inch (0.03-0.06 mm). There just needs to be enough room for a layer of heavy grease in the bushings where the axle bosses didn’t need any room at all.
Enough words time for work.
