Troybilt Trimmer Broken Pull Cord Repair Help

Nov 9, 2014#1

I have a Troybilt TB25CS trimmer in which the pull cord has been pulled all of the way out of the unit and won't retract. Can anyone provide instructions on how to repair this? Written instructions and/or a video to view. I am told that this is a fairly "complicated" procedure. True? Thanks!

I have the tb20cs model. I have looked at a diagram of yours and their starting system is very similar. I will try to create a video on how to fix this and post it within a few days.

Great. Thanks a lot. I appreciate the help.

Before taking it apart, it may help to kick the trimmer engine several times (yes, I'm serious.) If the starter is jammed, this could free it up. Tell me if it does!

I "beat" on the side and top of the unit with a rubber mallet. This retracted the cord back into the unit. I had to do this several times(pull/retract) before it allowed me to get the unit to start.

I hope that this solves the issue but am thinking that it might be a short term solution before it happens again.

Two things I have seen on MTD trimmer the last few years are starter housing that appear to warp, and jam the recoil rope, and the starter pawls on the flywheel bending at a 90 degree angle.

I am glad that helped! Since it was just a short term solution, will still post a video on how to get the housing off sometime today.

I created the video, but I can't post it. The forum program only accepts links to existing online videos. So, I began taking pictures to make an illustrated how to. Sorry about the inconvenience. The article should be finished and posted tomorrow.

Just a thought, could the video be posted to Youtube for others to use as well?

Take the screws out of the handle and remove it.

Remove screws from the side of the clutch cover

Insert a flatblade screwdriver into the crack at the bottom of the clutch cover and pry it open while removing the trimmer boom

Unplug the spark plug wire

Remove the screws that hold the bottom cover on

Remove the bottom cover. This cover is sandwiched between the front and back covers, so you will have to pull and jiggle it to get it off.

Remove 3 screws in the clutch cover

Remove the clutch cover

Insert a screwdriver or rod between the fins of the flywheel and brace it against the crankcase as shown. Make sure that the magnet assembly presses against the screwdriver instead of the flywheel fins so that you do not break one of the fins.

Remove a screw inside the clutch

Remove the clutch drum

Use a wrench to unscrew the base of the clutch. Observe the markings on the clutch base to see which way to turn it.

If you have any questions or run into any problems while taking the trimmer apart, post them. When you have it apart, inspect the blower housing/crank assembly for any problems. Post pictures of it too. If you need help getting it back together after the repair, I have taken pictures for that also. I will keep checking this thread until your repair is completed.

Thanks. It might be a week or two prior to getting to the repair. Thanks for all of the effort!!

Just curious, before taking it apart, am I going to need a new rope even though the rope is not broken?

If the current rope is in good condition, you shouldn't have to replace it. The rope should still be intact after disassembly. If the crank is warped, however, you would have to replace the crank housing, which comes with a rope installed. The crank housing is about $20, you might be able to get one cheaper on eBay.

Primer,

Great instructions although I got stuck at the part that says,
"Use a wrench to unscrew the base of the clutch. Observe the markings on the clutch base to see which way to turn it." I can't figure out how to get the base of the clutch loose and off. Is the base beneath the surface which doesn't allow the base to turn? Can you please provide a bit more clarification. The process was going well until that step. Thanks!

The blue thing in the picture is a wrench. After locking the flywheel in place with your screwdriver, turn the wrench in the direction of the arrow.

Sorry I didn't reply sooner! :frown:

And while you have it apart, replace the cord it is only $ 2.
Even the whole unit at $ 20 is worth considering as it is a big job ( time wise ) to pull it apart & put it back together again.
A workshop will charge 1 to 2 hours for the job which ends up costing more than a replacement trimmer so we rarely fix them.
The rule of thumb is starter on the shaft side = throw away, starter on the free end = repairable unit.
