Note that after stub axle is resting on lower cross tube there may be some residual compression in main spring but you can usually just wiggle it out, and back in again later.
I have found that if you position the axles stands close to the crosshead rather than the kingpin it makes it a bit easier
Be careful re-engaging oiler bolt. The kingpin thread is quite fine with posssibility to cross thread. A short tapered drift used to align all the parts it fits through is ideal but others manage with a screwdriver or hex key as large as will fit, taking care not to damage threads.
I replaced my kingpin bolts with stainless versions from John Worrall, so I bunged one of the old bolts in the lathe and turned off the threads in a gentle taper. Works a treat.
