Default Re: Undersized Kingpins .... NEW

At our shop we use a Sunnen piston pin machine to fit kingpins to new bushings. With the declining quality of replacement parts, using a reamer, as we used to do, usually results in an unacceptable fit. If you have a good machine shop in your area, take the spindles bushings, and pins there before you assemble them.

Only option to use the undersized pins is fit the new pins to the bushings on a sunnen hone and then shrink the axle and ream it to size with an adjustable reamer.

But in reality i would toss the junk replacement parts and find some NORS old stuff and start over.

This undersized kingpin story is sounding like the wheel cylinder bullshit a few years back. The vendors cant return the defective stock to the overseas manufacture and just try and shuck it over to the consumer. It took alot of bitching over the wheel cylinder problem to finally get the vendor to admit they were machined wrong

Correct me if I'm wrong but wouldn't the undersized pin rock on the retaining pin. I would think you want a fairly snug fit in the axle hole and .005 would result in play. My 49 actually has slightly oversized king pins to eliminate that problem. No matter how hard I drove the tapered pin they rocked.

Yes frank miller, that was my point... unless you did as skidmarks says and actually reduce the size of the end of the axle to resolve it.... but then next time when the new kit is actually correct... you have to go back!
