Jet 16-32 Drum Sander

[murphy]

I have a Jet 16-32 Drum Sander and it has worked fine for years but lately it bogs down with slight pressure, I have always taken very light passes as I know it is not a thicknesser, but now all but the lightest pass and it stops mid way through the length, I have tried to see what is at fault but it is difficult to see, I have removed the drum and checked the large coupler which is tight on the motor shaft and the drum, both have a keyway which the grubscrew tightens down on so there is no slipage there, I wonder if the main motor is knackered, that is all I can think of, unless someone can suggest something else to try

Are all the bearings ok, with pressure on the drum can you turn in by hand easily?

Thanks Fitzroy, yes I have checked the bearings and they are fine,

It’s definitely the drum stalling, not the power feed belt?

Might be worth checking the cap(s) on the motor. My 22-44 version has a cap-start cap-run motor. If yours is the same, it might lack torque if the run cap has gone.

Thanks guineafowl, I have a friend who is an electrician and he is going to check it out for me

Where can I get a new Capacitor, does it need to be ordered from Toolfrance, the part no. is JWDS1632-154SC the motor is shown in the parts list but not the Capacitor, just the part number

Does the cap have the capacitance in microfarads (uF) and the voltage written upon it? If so you can buy it from any reputable electronic distributor eg. RS Components, Farnell/CPC, etc or you can get them through the long river or E buy gum! But the quality may be questionable.

Thanks Martin
I have emailed the Toolfrance outlet in Rugby UK to see if the have any in stock, as you said other brands might be cheaper but lower quality, I don't suppose a capacitor is very expensive anyway

Depends upon the capacitance. Can range from three or four squid upwards. Check that VAT is included with the sites I recommended.
