Starter Spring 545008010

1. Removed old spring and casing.
2. Installed new spring and casing.
3. Wound the spring with rope assembly to proper tension.
4. Tested it to insure it would retract properly (this took some doing to get it perfect, actually unwound it one revolution per time to test in order to insure proper tension, too tight and it would not retract properly, too loose and it would not retract at all)
5. Put it all back together and tested tension the final time.

Took the front of the trimmer off and the spring was right there. Removed the clips holding the starter pulley on, took out the pulley and then lifted out the old spring and installed the new one.

The most annoying part of this repair is getting to the spring. After you drain the gas out of it, you flip it over and start removing the Torx screws that hold the covers on it. When you get to the round disc that is bolted to the engine crankshaft, you need to remove the spark plug and stick some rope down the piston cylinder. Now when you turn the disc to remove it, the crank is held in place by the rope you have in the cylinder and it comes off, without goofing up the engine. After that, the spring is accessible. I recommend checking out You-Tube for a view of one of the many videos.

Just keep the screws in a way that you remember which goes where. I scratched in the plastic where the short and long screws went, You may want to right them down, if you care about little scratches in the plastic

I saw your You Tube video on how to do this repair. Even though it's not the same brand as mine, It gave me great insight on how to replace my spring. This is the video https://www.youtube.com/watch?v=c2lS44AaR9w I hope this will help some of you that have the same problem.

1. Obtain a parts breakdown diagram for your trimmer.
2. Using the above, determine what has to come off and how to get it off.
3. In my case, the shaft came off first by removing the Allen bolts. Tip: spray bolts with Kroil Oil or equivalent.
4. Remove the clutch cover by removing 4 Allen bolts. top cover comes off and lower cover just comes off next exposing the clutch.
5. Remove the clutch by following the directions on the clutch. Keep parts in order/together as you remove them.
6. Remove the cover right below the clutch with the starter rope assembly.
7. Replace the starter rope and the spring.
8. Reassemble in the reverse order.
9. Now put on the rope handle pulling out the rope until the spring holds the rope handle flush to the case. You adjust by adding knots down the rope as needed to get the handle flush.
10. Test the repair.
