General Tormek Questions / Re: Newbie with rotational problem

Thanks Herman

It's definitely the capacitor. I have updated the thread with how to get to it, the size, connectors, electrical values etc.

General Tormek Questions / Re: Wheel doesn't start on its own

March 07, 2014, 10:11:08 AM

On the Supergrind 2000, to get to the start capacitor, take of the buffing wheel, its a 19mm spanner and its a standard direction thread. The capacitor is between the motor and the back plate of the grinder and is bolted using a 13mm spanner, the motor will swing away to give you access. The start capacitor is 4uF 400V B or 450V C. The body is 29.4mm diameter and 50.3mm long. There are 4 spade terminals at one end of which only 2 are used. There are only 2 connections to the component but 2 spade terminals per connection, I checked this with a meter. There is a black cap that covers the spade connectors.

Replacements seem to be around 3 GBP plus postage and they are ubiquitous, used in many appliances such as vacuum cleaners etc.

I'm putting my grinder back together while I order one as it takes 2 minutes to do this and I can keep using it with a little kick by hand

You can get capacitors with fly leads, I would get the same form factor with spade connectors, there are loads on fleabay. Physical size wise, I wouldn't get it any fatter but a bit longer seems fine, the replacement I have ordered is 25mm x 55mm. It also comes with a cap for the spade connectors.

General Tormek Questions / Newbie with rotational problem

Hi everybody
I've had a Tormek Supergrind 2000 for a few years now, I've used it occasionally but recently I have been using it more frequently, mainly due to buying the drill jig and I've also got a few more woodworking projects on the go.

I'm not sure when it started, but I have to give the wheel a nudge before it will go, otherwise it sits and buzzes. I'm guessing it is the start capacitor being single phase however I haven't investigated it yet, I thought I would ask on here first to see if anyone else has had a similar problem.

If my diagnosis is right, I'm guessing this should be an easy fix, I replaced the start capacitor on my 3HP compressor recently so this should be simple?

Regards
Andy
