Husky Winch Brushes?

Recommended Posts

Hi All

I am at the moment refurbing a Husky winch. While its apart i thought it might be a good idea to fit new brushes to the motor. Now i have the parts manual and been trough the parts suppliers and no one seems to list the brushes separately (unlike other makes). Does anyone know if you can find replacements? or have the specs (lenght) of what they should be as new?

Motor used to work when tested, not under load, loads and loads of black dust inside (brushes?) no corrosion or water ingress damage.

Tips and advise welcome.

 

Regards Grem

Another question, will one shot swivel grease work in the spur gearbox?

Hi Western thanks again, in fact i will source the lubricants locally as its not worth having them sent over here.

Just sent a mail to first four now we see their reply.

Please note the Husky requires a special grade oil - stick to it.

The gearbox / wormwheel needs that to work correctly..

First Four usu. has the correct stuff.

Thanks guys,

 

Just ordered a fresh set of brushes (https://www.al-electric.de/), as mine were quite worn, next i will lightly skim the commutator so it has a fresh face. Motor should be like new when done.

Just need to deciede what colour to repaint the winch........ original red or black.............
