Replacement carbon brushes, where to buy.

Sometimes you can take a similar brush and file it down to fit. Good luck.

This seller on eBay might be of some help. He is a supplier of motor brushes and had the odd ones that I needed.

Go on eBay and search for optosteel.

Most of the time sparks in these tools come from where the brushes make contact with the armature. Some causes for sparks are: The brushes are worn down to where they don't make firm contact with the armature. Brush springs overheated and no longer push the brush down on the armature. The comutator on the armature is damaged and causes the brushes to spark excessivly. You can take it apart and try to find which parts are hurt but I don't know if any Clarke Power Products parts are still available. The company went out of business around 2009 so you'd have to find someone with left over parts. It may be easier to buy new and go with a name brand and new warranty.

You can get carbon brushes from any electric motor - have a look around scrap dealers for vacuum cleaners, washing machines, alternators from cars etc - you may find an appropriate brush from there.

You can also try eBay
or the manufacturer's website

Remington Saws have ceased operations and, unless you like to make your own replacement parts, they are prone to failure. The gearbox is sealed and the motor brushes are not available anywhere. Look elsewhere!
