Zoinks! Casting Numbers for Springer Legs

#1

Post by flatheadDave »

So Im wondering what kind of legs these are on the "1948 45 cu" I bought. I can't seem to find any solid reference to the casting marks in Palmers book. So I wanted to ask you guys, what do I have here?

If someone could provide a chart or table for casting numbers for BT and 45s, that would be AWESOME.

I read somewhere online that this might be a 1940 XA front end, but I wanted to ask the forum
thanks gents!

What edition "Palmer's" are you looking at? All the reference info is in there. A #5 front leg is 40 or 41.
And no, that isn't an XA front end. (Which are all '42s by the way, no such thing as a '40 XA.) All XA forks are 1" stem, 2-3/8" longer than standard, and use 45 rockers and wheels. The only '40 and '41 models with a &/8" stem and outside big twin type rockers was a Servi-Car. WLCs used the same wheel and rockers but did not exist yet and do not use #5 front legs.
