can a DIYer install withg little difficulty? Any video on the subject available?

I can't seem to stop the rotor from turning so that I can take the bolt out to change the blade.

I took apart my 5150 circular saw expecting to see corrosion. I found both brushes worn with one the springs popped out. Further diagnosis found three of the 16 sections of the armature ground down, I suppose due to the piece of the brush holder or whatever caused the brush holder to break. Could this be a defect? Will this ground section of the armature cause the motor not to run? Is it possible that replacing the brushes is all that is needed?

I have a old SkilSaw. It is a worm drive. I cannot seem to find a bolt that holds the blade in. It is a model 367. I cannot tell the size other than it is left handed. I would appreciate any help in locating this and also the worm gear lube.
Thanks

My brother plugged my saw into a 210 plug and burnt it up. When you pull the trigger it sparks and smells bad. I was wondering if I need more than the carbon brushes to fix the problem?

The depth lock (parts 85,86,87) needs a bolt. An ordinary bolt might do, but it would have to have a thin head so that it didn't hit the blade guard. On my saw, this bolt has a head like a rivet. Is this bolt/rivet in the parts list?

I need a wiring diagram for the switch on the Skilsaw Model 5510! Thanks!

I need a wiring diagram for the switch. Can you please help?
Thanks!

the spring from the blade guard broke where are the attach points for the spring

How do you change bearings on the HD5510?

My saw doesn't work when I turn on the switch. The blade doesn't rotate. How can I troubleshoot the problem?

I think my Craftsman 135.27540 5 1/2 inch Circular saw is identical to the Skil HD5510.

The side edge of the baseplate on my saw isn't parallel to the face of the blade. So when I run the baseplate along a guide, the blade is cutting at an angle and it wanders or burns.

When I purchased the saw (new), the metal band with the depth adjustment slot (the one that HD5510 parts 85,86,87 slide along, it sticks up like a fin from the baseplate) was twisted and it was hard to adjust the depth of cut. However, I think this twist was what aligned the edge of the base plate and the blade. I untwisted it and this probably caused the problem.

I'd like fix the alignment without re-twisting the band, even if it means making a modification to the saw. Have any other members had experience in this matter?

It's unclear to me whether getting a new baseplate would solve anything. I'm not sure whether my saw was mis-manufactured or whether all the saws were aligned by twisting that metal band.

A even simpler question for HD5510 owners. If you hold a square across the front face of the assembly on the base plate that holds the bevel adjustment, do you find that the other arm of the square is parallel to the left edge of the base plate? On my saw, at the back of the plate, the line of the square is off the edge by about 1/16 th inch.

Love the saw but cannot find new blades in our shopping area. I purchased the saw from Sears but they do not stock the blades.

I love this tool,it cuts everything from wood,plastic aluminum,etc. I use it on the jobsites daily.I have to keep an eye on it because everybody loves it. I have a skill wormdrive and it is very heavy.I only use it for more rigerous jobs.Once again this is a tool that sells itself when used in front of other tradesmen,it is trully remarkable.
