Hi, this is my first post in this forum. I think I need some help and recommendations
Recently I was having some oil leakage from the Apron on my WM250V lathe and decided to try fix this.
I disassembled the leadscrew from the gearbox, detached the apron from the carriage and removed the entire Apron.
When having the Apron separated on the table I started to dissassembly it to it's separate components (e.g. removing gears and shafts), trying to see where the leaking oil originated from.
After almost everything was broken down, I found the issue:
Worn out O-ring on the shaft used for closing the half-nut.
After replacing the O-ring and reassembling everything It seems like the carriage is moving much too tight when close to the head-stock.
E.g. I find it very hard to turn the hand-wheel on the apron when coming close to the headstock.
All gears etc, move perfectly smooth when carriage is in the middle of the ways, and also when apron is not tightly screwed to the carriage (even close to the head-stock).
Also detaching the lead-screw from the gearbox shaft "solves" the tightness, so I've boiled down the problem to be related to the lead-screw being to far from the ways when close to the headstock (sub-mm distance)
However I have no clue what could have caused this to happen or how I should fix it.
The two removable pieces on the backside of the apron holding the half-nut and the power feed wormgear did have dual solid pins for ensuring correct placement, along with four bolts each. So I doubt I could have refitted these wrong, but...
Is there any way of adjusting the height of the leadscrew ends that I missed out on? Or do somebody have any idea of what could have gone wrong.
Attaching some pics from the procedure...
