A description of the fault:-

The motor is running but the blade is not turning.

The motor was stripped down and found that the armature (motor) was OK and brushes were fine.

The problem was with the front gear which was just free wheeling on the shaft which the blade is attached to. This gear engages with a gear on the shaft from the armature but of course this has lost it’s drive hence the motor turns but not the blade.

The gear is obviously heat shrunk onto the front shaft but even though this has been tapped back into place and appears to be holding fast it starts to slip again when reassembled.

Is there a fix for this and are spares available?
 
Hello and welcome, I can't make any sense of the users manuals of any version on this table saw.
I suggest you get 3 posts in and then you are able send some pics, sizing is a click on the for sale forum.
Regards Rodders
 
The manual shows the whole motor as 1 unit. Depending on what you paid for it, it might be worth buying a new motor.

If you want to play with it. and of course, with it UNPLUGGED, check the other gears for movement. maybe theres something wrong between that cog and the blade.
If everything is turning freely. the only trick I can suggest is you remove the loose cog, clean it all very thoroughly, and reassemble using loctite

Bonded Press Fit

In press fit assemblies, where parts are manufactured with interference, the load is transmitted by both friction between the parts and the cured LOCTITE anaerobic Retaining Compound. Bonded press fits are typically used under low to medium dynamic loads, when torsional movement, axial or bending load level is medium or with thermal load.


Benefits

Leads to a considerable strength increase when used with existing designs
Allows use of lower interference, resulting in
- Comparable high strength level
- Lower radial stresses
- Improved fatigue resistance

Bonded press fits are used for assembling railway wheel rims, pulleys on shafts, differential ring gears onto hubs, engineered timing chain sprockets, engineered driving shafts.

Application

The adhesive is generally applied best as a film to one or both surfaces. To guarantee an optimum coverage and distribution of adhesive, chamfers on the leading edge of both hub and shaft are necessary.

The assembly process should be done, axially aligned, in one fast movement to avoid adhesive pre-cure, which leads to lower final strength.
