Check all the things mentioned above before re-cutting the thread. If you do need to re-cut it I had no difficulty finding a left handed tap, and I assume a die would be available. If you get a split

Thanks Jerry, Good point on the reversed thread didn't even cross my mind. I've given it a clean and re-grease. It's running much smoother but it does appear to have a bit of a bend in it when I wind

Kallum, You do know this is a left-hand thread, so tap and die need to be left handed. Also, the cross slide may not move freely if the locking screw is still engaged. Before even thinking about

On the unimat SL I just purchased it looks like the thread has been crushed a bit. This? makes it difficult to use the . I'm thinking of running a tap through the cross slide support and a die over

So I traded a guy a motor that would trip the breaker for one that wouldn’t. Since I am an electronics tech and I have overhauled a half dozen U90 motors I was confident in the swap. Noise

Did you use the same type of bearing that're already in the headstock or a different type?

I've stripped the whole thing down and reassembled. Bushes are fine and very little carbon build up. I will go through at some point and try rebuild it and rewire but for now I have ordered a

Check that the brushes are still good & check how much carbon build up is in the motor. Capacitors may be shot too. Both can trip circuit protection. When you pull the motor apart place indexing marks

I had to repair the capacitor in mine wasn’t a hard job just split the motor casing and swap out the capacitor while your there clean you can clean out the carbon dust and replace the brushes....

I can almost guarantee that there's old dirt and oil and carbon from the brushes inside the motor and shorting the power to ground. Is the breaker a GFCI (USA)? I.e., does it have *Test* and *Reset*

Thanks, Mine trips the power the second I turn it on. I get the feeling the capacitor is shot as everything else looks fine. I've done some reading since I originally posted and I'm going to install a

I forgot to mention my NVR switch was ?20 it’s a single phase NVR without E stop but you can fit one with if you want, I find it pointless since the has to braking function anyway so it wouldn’t

The U90 motor is practically indestructible. I know many members believe it has an intermittent rating, but I have seen many of them, and never seen a sticker on it that said so. I don't think there

Mine did the same.... At first I thought it was the original switch as it tripped more often when I flicked the machine on, so I swapped it out to an NVR switch unit... that for the most part seamed

Just purchased a Emco Unimat SL and it keeps tripping the power in my house. Any ideas as to why? I'm in Australia so we use 240v single phase 10A. Motor details KUS 99, 240V, 95W, Mot.Nr: 752953
