Introduction: Premier Wonder Grinder Repair - Belts and Gears

Whether you're using the Premier to grind lentils or cocoa nibs to make chocolate, these machines definitely do wear down and need maintenance, especially if you notice black soot gathering around the base.

Bhavani is the main guy in the US who sells spare parts for these grinders, and it is highly recommend that you contact him rather than trying to find random parts for these grinders. He can be reached at bhavani@dtnj.com

The single most important thing to remember about working on any piece of electric equipment - UNPLUG THE MACHINE BEFORE DOING ANY WORK! I cannot stress this enough. Even with the machine unplugged, there is always still the risk of electric shock. Do not dissemble the grinder any further than these steps - there's really nothing else you can work on.

Step 1: Unscrew the Metal Shaft

Before doing anything else, unplug the Premier and hit the on/off switch to make sure there's no residual charge.

You may have to use quite a bit of force but these do unscrew.

Step 2: Pop Off the Plastic Ring Around the Drive Shaft

You can do this with finger pressure.

Step 3: Pop Out the Rubber Plugs From the Cover

Step 5: Look at Your Gears

There are three things to work on - the large plastic gear, the smaller aluminum gear, and the belt that connects the aluminum gear to the motor.

The plastic gear pops off the base with significant force.

The aluminum gear is bolted to the base and can be unscrewed.

Step 6: Line Everything Up

When you're putting the plastic cover on, make sure the power button is resting on the spring which sits on the red power switch. The back of the cover has a slot for the power cord. This can be a bit tricky to line up.

Step 7: Screw Your Base Back in and Replace the Rubber Covers

Step 8: Document Your Maintenence

Especially when you have more than one grinder (we seem to get a new one every month or so these days), it's important to document which grinder is at which stage. We've noticed the serial numbers gradually going up with each new grinder we buy, so we write the serial number on the side so we can easily see which machine is which, and what maintenance was done.

Now that you've completed these steps, get back to grinding!
