Grasp the outer spool in one hand, and turn the "bump knob" counterclockwise to remove it. Pull the spool assembly off of the trimmer head.
Separate the inner reel from the outer spool. Remove the spring from the inner reel and set it aside.
Remove the old line if necessary, and clean the surfaces of inner reel, outer spool and trimmer shaft.Cut a 20-foot length from a spool of bulk trimmer line. Use only .08-inch replacement line.
Fold the line in half and insert each end into one of the two holes located near the hub of the inner reel. Pull the line all the way through the holes, bringing the loop as close to the surface of the reel as possible.
Wind the line in the direction indicated by the arrow on the reel. Keep your index finger between the two halves to prevent them from overlapping as you wrap in tight, even turns.
Insert the one end of the line into each of the holding slots located on either side of the inner reel.
Thread the ends through the holes in the outer spool. Replace the spring into the inner reel and place the reel into the outer spool.
Grasp the outer spool and inner reel, and pull on the ends of the line to release the line from the holding slots.
Reinstall the reel and spool by placing it on the shaft and screwing the bump knob clockwise onto the assembly.

Take care.

TB525es attachments no longer working

NOT THE CLUTCH.. Mine started doing the same thing recently...what I found is the metal piece at the end of the main shaft that accepts the drive from the accessory was stripped out....the part from MTD/Troybilt is $60... Save the $60 its an easy fix....

Remove the sleeve at the end of main shaft.... clean thoroughly with brake cleaner...

Mix a small amount of JB Weld and fill along the walls of the "rounded out" area..Let set for about 2 hours so it gets firm but soft...

Take an attachment, and slide it up into the receiver..making sure to align them square with the receiver. this will form the JB Weld putty to the drive piece. remove the attachment immediately!!!.
Then let it set over night.... DONE works like a champ again next day.....

How do you restring the line on the spool? I can't get the spool off but have managed to rethread it. Just can't figure out which direction the line should be wound.

there should be screws in the corners/middle at the back of the head. Phillips/torx head, once they are removed,you can separate the housing and then you will need to wind the the spool counter-clockwise, note the cord is not attached, once you believe you have wound the spool enough, you will need to feed the cord through, tie a knot, burn the end and the let go of the spool and it will retract the cord, pull a couple of times to make sure the knot is holding, then reassemble and start weed eating. Good Luck Tim

Someone borrowed my 4 cycle engine cultivator and put a gas and 2 cycle oil mix in the tank. Has that caused any major damage to the motor as long as I flush out with straight gas?

It shouldn't have caused any damage, I would empty the tank, float bowl, pull off the feed line and drain it. You might want some ether ('starter fluid') at hand in case there are traces of oil in the fuel lines making it reluctant to start.

Describe string replacement Troy- Bilt TB5755SS

Cut two separate pieces of string, about 7 ft. each.

Stick the end of the line in the hole on the inside of spool.

Wind clockwise onto spool, putting the line that is closest to the ground on first.

Once you have winded this piece on, lock the last 4 inches of line through the slits on spool.

Repeat process for second piece of line, locking the last 4 inches in slot opposite the other locked in piece.

Put the spool on the trimmer, feeding the end of lines through either hole on trimmer.

Before you push the spool all the way on, pull the strings out of the locked position.
