Spitfire bearings

[Jeff Monks <monksj@db.erau.edu>]

Does anyone have any experience in replacing rear wheel bearings on a 
Spitfire?  According to my Haynes manual, a special tool or hydraulic 
extractor is required to get the hub off.  Since I'm not likely to find 
Special Tool S4221A anytime soon, I was wondering if anyone had any 
experience using something slightly more accessible, such as a gear 
puller or some such device.  Anyone?  Or am I going to actually have to 
find one of these things to get the hubs off?

Thanks in advance,

Jeff
