As title, has anyone removed the outer for the front spindle bearing from the headstock casting proper on a later l5/l5a harrison lathe? Its the model with the small half lid on the very top of the headstock, not the split larger cover of the earlier one.
I get it has to come forward because I've got a second spindle ready to go in that arrived with a new front bearing and I can see the lip on the front edge, but so far I have taken the original spindle out and left the big gear sitting in situ.
It *looks* like the second shaft/gear selectors etc have to come out to swing the big sliding gear on the mainshaft around to fit out the lid aparture to get behind the bearing to drive it forward, which means total headstock strip down. Unless I'm missing a trick?
So if I did do a total stripdown of the second shaft/selectors etc, would the bearing outer drift out the housing fairly easy at ambient temperature or would the casting need heating to expand it and some sort of bearing extractor setup be required?
Seriously contemplating just fitting the original bearing on the new spindle if its a pig of a job requiring a total strip down, so I dont have to change it... Its not really worn...
If anyone's curious, its finally getting a L00 fitment spindle from a L5A in place of the 2.25" threaded nose fitment thats been on it so far for various reasons.
