Hlt16 dual string head spool does not have divider for each string how is string installed

I have a Ryobi Model RY28040 straight shaft line trimmer. In my case I replaced the complete String Head Assembly that includes the String Head Housing, Spring, and Spool and the string still did not advance. I then discovered that the bolt in the Spool Retainer cap (the red cap that attaches the spool to the shaft) was fused and not moving. The bolt needs to be loose inside the cap in order to allow the spool to move in and out by the spring. I loosened the bolt and fastened the spool back onto the shaft. Fired it up and bumped it a few times and the line began to advance. Turns out I probably only needed to replace the Spool Retainer rather than the String Head Assembly.

In your manual under section 12: Line Head Installation. You will do the opposite of what it says here. The key is to LOCK the gear drive so the flex-drive shaft won't turn WHEN you are removing the trimmer head. They use a special tool (maybe you have it). But a small-shafted Phillips screwdriver or the like can be put in the drive hole to lock the gearing up as well. Look for the hole in the upper plate and align with the notch in the drive housing and grasping the entire string head unit, remove it. Here is your manual, see Section 12

1.Twist the cap off counterclockwise.

2. Remove the cap and spool.

Note: If the spring falls off, install it before installing the spool.

3. Thoroughly clean the cutting head and cap and inspect them for anydamaged or worn parts.

Hello, W/D here.

Read all the way through this, with the spool in your hand, before you re-wind the spools. It will make much more sense!

Pull the spool off of the trimmer.
Look on the bottom of the spool. The decimal numbers next to the notches on the edge is your line size (e g. .080). If there are 4 notches, there will be different decimal numbers, indicating that your trimmer can take different line sizes.
Also on the bottom will be arrows, indicating the direction that you will need to wind the line.
Looking at the spool, you'll notice that it is actually 2 spools, and the divider between them has a slot in it. (This will be important in a minute). The section of the spool closest to the bump head is the outer spool, and the spool closest to the machine, with the flat side, is the inner spool.
Insert the proper sized line into the hole in the inner spool core about 1/8", and wind in the direction indicated by the arrows, until the line is just about even with the divider between the two spools, then place the line in the notch that is 180 degrees (on the other side of the spool) from the slot in the divider. When the line is in the notch securely, leave about a 6" tail beyond that, and snip the line.
Wind the outer spool in the same manner, but this time, the line will go into the slot in the divider, then into the notch, and also get a 6" tail.
Feed the tails into the grommets in the trimmer head, square them up, notches to grommets, and snap the spool in.
Push the spool in like you were bumping it to the ground (this frees up the advance for the spool).
Grab the two tails, and give a tug. The line will pull out of the notches and advance about 1".
It's a good idea to clean out the hole where tha spool fits onto the trimmer from time to time, and also to put some graphite dust in the hole every 8-10 times you re-wind the spools, just to keep the mechanism working freely.

Best regards, --W/D--

The slots on the string spool are there just to hold the line in place so it doesn't unwind while you are putting the string head back together. You have the strings sticking up, you lower the casing with the eyelet holes down, feed the ends of the strings sticking up through the eyes and then yank them free of the slots so they can automatically feed. So yes, line goes from spool hub to spool slots to casing outlet holes and don't forget to pull it free of the slots.

If it is a duel line trimmer then:

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.

If it is a single line trimmer: Then just wind a single piece of string clockwise onto spool. This may need to be longer than 7ft.

YOU MUST REMOVE THE STRING HEAD YOU SHOULD HAVE TWO PEICES THE IUTER HOUSING YOU SHOULD CLEAN THE INNER SPOOL REMOVE ANY OLD STRING AND LOOK ON THE BOTTOM THERE SHOULD BEARROWS TO TELL YOU WHICH WAY TO WIND THE NEW STRING

Go to home depot. look at the floor model and the replacement spools they sell there. Reverse engineer the stringing process or but a pre-loaded spool.
Otherwise,
1. Squeeze the tabs on the side of the head of the unit to remove the spool cover.
2. remove spool.
3. place end of string in small hole in center ring of spool.
4. wide spool with string in the direction of the arrows printed on the spool. DO NOT OVERLOAD!.
5. snap string into notch on spool and cut string leaving 6" exposed.
6. thread 6" of string through hole in side of unit head, replace spool, and replace cover.
7. go cut grass.

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.

Or sometimes you unscrew a retaining bolt set into a plastic "lug", the spool drops out, refill t with line, replace it putting line through holes in the spool casing, refit the "lug" and tighten it again. I think I have the manual for this though and if so maybe I can send you a link to images on MSN Homepage to help you..
