Need help with replacing starter cord on Troy Bilt trimmer

I have a Troy-Bilt TB525CS trimmer which needs a new starter assembly.  It is under warranty but I now find that means nothing and I will be charged $60 to check it out and the shop tells me Troy-Bilt won't honor the warranty so it's a waste of time.  I decided to order the part and replace it myself, couldn't be that hard, I have been a mechanic for years.  Well, I got the trimmer apart and now I can't get the motor out because the flywheel is preventing me from removing the engine shroud, the red plastic shroud which covers the front of the engine.  The flywheel is about 3'' around and has a nose shaft on it.  It looks like there is an allen screw holding it onto the crankshaft, but I cant get anything to fit the screw.  Do I need a special tool to press this off the shaft?

    Hi Mr. Fix-it, thanks for the reply.  I looked online for an IPB diagram and I realized I am not using the correct terminology for the parts I need to remove.  First of all, I already removed the shaft and the throttle assembly.  I also removed the clutch cover which was just a plastic housing.  What I need to remove now is the clutch drum.  The clutch drum looks like a small automtive brake drum, and it houses the centrifigul clutch.  I thought there was a screw in the center but after looking at the parts breakdown, there is no screw listed or shown on the diagram.  I don't understand how this comes off the crankshaft since I can't unscrew it, it just spins on a bearing.  Do I need some kind of puller?

    Thank you again for the help Mr Fixit.  I just finished putting it back together and it works great.  I pulled the spark plug and stuck a 1/4" extension in there and used a T-20 screwdriver to remove the screw.  Then once I got the clutch drum off, I found the clutch assembly and hit it twice with a brass drift and it loosened up and came off.  I had a little trouble getting the starter return spring set correctly, but I figured out a way to get some preload on it and it pulls perfectly now.  I stowed the starter rope in the pulley and turned the white plastic disc two turns clockwise before pulling the rope through the guide collar, this way it has plenty of spring pressure to pull the rope in.  You saved the day for me!!  I couldn't see paying $80+ for the repair and I ordered the part instead.  The jerks at the saw shop were joking around that they would see me back soon after I tried to install it myself... well, I got it done myself!!

sounds like you are trying to remove the drum assembly; try a torx driver or a phillips screwdriver. There is a srew that hold that drum on and the bolt is in that black hole.

SOURCE: What is the fuel line size for Troy Bilt TB525CS Trimmer?

Yes, something special to know. If the new fuel line is going into the gas tank, be sure to cut a steep angle on the end of the line going into the gas tank. This will allow enough of the line to get into the tank where you will be able to grab it thru the gas fill opening with needle nose pliers and pull it thru.

SOURCE: How do I fix/replace the starter rope on a TB20CS

Probably no special tools needed. Take the starter assy off. Turn the recoil in the direction it will turn if you are pulling the rope. When it gets tight, hold it there and install the new rope. When it is installed, let go of the recoil and it will draw the rope in.

You need to unscrew the black bumper button. I believe it is counter-clockwise. Mine was very tight and took a pair of channel lock pliers to loosen.
