Hi

Thanks for your help Dave. I have managed to make a bit of progress today. Very carefully putting a tapered brass drift down the hole under the grease nipple moved the outer shell a bit, and then a couple of hours of making up some brass levers and using them etc got it out. For future reference, the bearing is a Timken, numbered 03062 on the inner race, 03162 on the outer. I think the front one is the same but I haven't cleaned the filthy grease off yet.

Better lighting revealed a second grub screw at a 9 o'clock position at the front, which allowed access to the front bearing. Just waiting for the parts now.

Is there a reason why Dewhurst switches aren't good at on/off?

Hi. I've recently bought a Centec 2a which needs a bit of work. I've run into a bit of a problem with the bearings on the horizontal drive shaft within the main body of the vertical head. A v-belt that was too short (and so too tight) had been used, which I think has contributed to the rear bearing rollers being pitted and scored. I've got the shaft out no problem, but the rear bearing outer race is up a bit of a blind alley (I hope the 2nd photo will make it clear) with no way of getting a bearing puller onto it, and no way of getting a drift in behind. Any good tricks to get it out?

(sorry, but photos are on their sides!)

Also, does anyone know how to get to the front bearing? I can see where it is, but can't work out how to get there! There is a grub-screw on the top (see photo 1), and maybe one on the front face (although I can't find an allen key to fit it), but I can't see what they might release. Has anyone been here before and can offer some advice. I can't find a section drawing of the vertical head to refer to.

Many thanks.
