Question about Craftsman 25cc Gas Line Trimmer

1 Answer

The pull cord on my 25cc craftsman gas trimmer broke and went back inside the trimmer. I looked up several online site for assistance to replace the broken cord. At the point, I've removed the back cover, the spark plug and backed the Hex screw out as far as it could go. I am still unable to remove the front cover so that I can complete the task. Is there any suggest to removing the motor shaft from the front to get to the pulley assembly? Please help...Jimmie

You can't remove the motor shaft from the front. That is NOT what you are trying to do anyway. Here are all the steps you need to take to get to the pull start assembly which is located inside the front cover. Torx head screws are used exclusively on these but you may be able to grab some of the fasteners with a flat-blade screwdriver. I'm not sure if you have removed the clutch drum (has the screw that backs out but doesn't come out) so here you go.
Remove the tube that holds the flex-drive shaft from the front of the motor cover.Remove the rear engine cover. Remove the throttle cable from the carburetor. Mark and unplug any wires for the on/off switch that go to the ignition coil (underneath front cover) if possible. Now if you have pulled the driveshaft tube out of the way, the clutch drum is up next. Inside it, screwed into the very end of the engine's crankshaft is a Torx #25 screw. Before you loosen it, you will have to lock up the engine. To do so, remove the spark plug. Pull on the starter until the piston is down, then insert a length of clean, soft rope into the engine. The engine will come up and compress the rope, thus locking it in place to allow clutch drum and clutch removal. Loosen the T-25 screw inside the drum.. You may be able to remove it with a long thin-blade screwdriver also.It probably won't come completely out...it is made this way. Next, remove the clutch. It is screwed onto a small threaded section of the crankshaft Removal is counterclockwise.. It will be pretty tight. To help, apply peneterating oil. Whack the ears of the clutch near the center with a dull flat-blade chisel and hammer unless there are bolts. then use wrench. It will turn counterclockwise for removal and there will probably be a removal direction arrow on it's face. After getting that off, remove the Torx screws holding the cover to the engine. The starter unit should be mounted inside as it mates with the top of the flywheel to start the motor. Remember to preload tension (5-7 turns) on the starter unit. Make sure the handle is installed. Jam the unit with a screwdriver or vise grips so you can insert and tie off the new rope. Then remove jam device and let recoil pull your new rope into place while holding the handle. Reassemble and you are done. Disassembly requires Torx head drivers.

there are three or four screws on top take them out put them in order so you can put them back in the same order,carefuly pull out the housing examine the cord,there must be some extra dirt inside,clean it and then check the spring,maybe brocken,any local hardware store must have a replacement,if it is brocken take it with you to match,and put it back the same way,do not forget to wind up the spring about sevev turns,god luck

Pull cord won't pull


Check the shaft to see if there is something stuck in there. You can pull the wire shaft out to check. It is wire but looks like a small cable. Good luck...Lee

Broken pull cord


ur going to have to unmount the the motor from the shaft

step 1. Unbolt throttle housing

step 2. now with that out of the way u should see a clamp holding the motor to the shaft, loosen and pull the shaft out, there will be a cable, so make sure u have it lined up so it goes back into place

step 3, look at the back of the motor, u should see screws going into the plastic housing (coming in from back going into plastic)

step 4. once that is off pull the broken part of the cord out

step 5. wind up the starter coil, (it will only wind up one way) its spring loaded so be carful, once it stops back it off 1 full turn

step 6. u will see a hole for the cord in the housing and in the coil, make sure they are lined up

step 7. insert the cord through both holes, tie it as tighttttt as possible, then let the spring do the rest

step 8. put it back together

Broken pull cord


You have to take four allen screw out of the plastic that holds the engine on. There is also one by the spark plug that needs to come out. Once the engine is loose, you have to unplug one wire and unscrew the other. Then the engine should come off. Then loosen the two allen screws holding the pulley in and it will come out.

Craftsman 17" 25cc Trimmer...pull cord stuck


it's doubtful that bad gas caused this, it sounds like the cord was back-lashed and partially came off the recoil pulley. Remove the recoil cover and ensure the cord is all on the pulley, make sure the rewind mechanism works smoothly before re-installing.

REplacing the pulling cord on a gas trimmer


those are usaully under your pull start cover and if its broke you can buy a new rope but if its broke near handle i would open it and retie it to save ya money. but remember to wind spring a little to keep tension on it before pushing it through the hole for handle.
