Question about Bosch Saws
There are several steps:
Remove the base height adjustment lever assembly(#56,57,71,72,73,74)
Remove the lower blade guard (#37)
Remove the brushes (#810)
Remove the upper guard housing (#827)
The armature will usually slide out with the upper guard - once out wiggle the armature out of the guard housing.
Reverse order to reinstall

new Ryobi have a spindle lock button, it is unobtrusive and you may miss it
If yours does not, secondhand etc, a screwdriver in the blade teeth between the upper and lower guards provides a locking bar enough to undo the arbor bolt

turn the motor housing slightly until you can put a screwdriver between the housing and diaphragm, pull on the one side and push with the driver and it will come apart, I just did one yesterday. To get the armature out of the fan bearing you will need a dead blow hammer to tap on the diaphragm while pulling on the armature. The bearing is held in place with 2 screws, hope this helps.

Testimonial: "Hey thanks! It seems they really don't want you to work on the motor on this particular saw. Thanks again for your help. "
If you are mechanically inclined and it sounds that way do you have a volt ohms meter?? If so start at the cord and check the continuity to the brush holders. Why did you replace the field? You might have had a stuck brush or some other problem. Make sure the brushes move freely in the tubes and also look for discoloration on the commutator of the armature. Let me know what you find and I will try and help you thru the rest of it.
