1. Found the Clutch discs were obsolete. (Homelite bc900 and many other trimmers I found in my research.)
2. I discovered while researching that the clutch parts breakdown used the same clutch washer and the same drum, but it used a different clutch which wasn't obsolete. Purchased new clutch, drum, and the two different sized washers. Parts were for Ryobi BC30.
3. Removed the clutch drum by loosening captive torx screw in end of drum, sliding off the drum.
4. Removed the clutch each of the two clutch discs by tapping a screwdriver with a hammer to spin then off.
5. Removed old clutch washers.
6. Replaced washers and clutch in order for other model trimmer.
7. Tighten clutch with adjustable plier.
8. Installed new drum.

Trimmer
Parts Used:
Throttle Cable 15" - PS01177
Drum And Connector - 308177001
Repair Difficulty:
Easy
Time Spent Repairing:
30-60 minutes
Tools Used:
Screwdriver, Pliers, Socket set, Torx screwdriver, needle nose pliers, grease.
The trimmer head would not spin, although the engine was running at full throttle
1. Remove bolt and retaining pin between the upper and lower drive shaft assemblies.
2. Remove lower drive shaft assembly.
3. Remove all the torx screws on handle and separate the handle plastics.
4. Remove upper drive shaft assembly to gain access to the throttle cable and drum connector.
5. Disconnect electrical connections from main body.
6. Remove retaining bolt from throttle cable mount, remove cable from carburetor assembly.
7. You need to bind up the piston so the crankshaft doesn't turn before removing the screw to the clutch drum. Watch https://www.youtube.com/watch?v=bDDx2C2lDos for instruction.
7. Remove center screw from drum to engine connection,
8. Remove drum connector from centrifugal clutch.
9. Reinstall in reverse order, cleaning and greasing the drive shaft connections.

The root cause was the spot welds on the friction pad inside the connecting drum broke loose causing the head not to spin. Throttle cable was frayed at time of inspection so that was replaced as well.

Tool Type:
Chain Saw
Parts Used:
Spring and Container - 638033001
Drum And Connector - 308177001
Repair Difficulty:
Hard
Time Spent Repairing:
More than 2 hours
Tools Used:
Screwdriver, Pliers, Socket set, Wrench Set, Nutdriver, Torx head drivers
Starter cord handle broke and retracted.
First I would like to thank Mark and all his useful videos, without which I would have never been able to do this. His videos provided clear procedures that were easy to follow, and he puts on a better, more professional video with each new one he produces.
There are differences between the BC30 that I have and the SS30 in the video, so I would like to take this opportunity to go over the differences with anyone else who has this model.
1. The clutch drum takes a T20 Torx head driver, not a T25 used in the video, but the rest of the fasteners are T25.
2. The starter spring goes face down against the plastic ribs with the metal cover covering it, so the spring is not visible other than its center tab showing through the hole in the cover plate. The part is shown this way in the parts lists, too. Then you can set the 6-7 turn preload in a clockwise (vice a clockwise) fashion, attach your starter cord, and the cord will retract properly (counter clockwise). For this part it's a definitely good to have a helper when tying the cord, I'm just not good at one handed tying like Mark.
3. Mine uses the two clutch plates, too. Put the first one on in a reverse shape like Mark does, and the second in a normal. This way the two clutch plate surfaces with the small dimple will be facing each other. The dimples don't have to exactly face each other, just the surfaces, so even if the dimples are 180 off it's still ok.
4. I use mine as a pole saw and have several other Expand-it attachments, so make sure the clutch drum engages properly with the drive pin inside the pole and doesn't get positioned off center.
5. If your trimmer won't start, try reversing the electrical leads to the cutoff switch, they are not marked. The right way it will start (eventually), the wrong way it will never start.

Also replaced the fuel tank the lines were cracking and sucking air, making priming impossible. The tank comes with the lines pre attached and Mark has a useful video on this, too. Also cleaned the carburetor with carburetor cleaner and cleaned the sponge style air filter. Now it runs and drives the saw again!
