Problem disassembling a WeedEater 1214 to replace the Hub Assembly

by Manage My Life Last activity date:
October 3rd, 2011

I have not been able to disassemble a very old WeedEater (brand name) 1214 (electric) to replace the Hub Assembly. It appears that the Drive Gear threads onto the motor shaft. I have tried to unscrew the Drive Gear with a wrench (using quite a bit of torque) but I fear I will break the plastic Drive Gear, and perhaps damage the motor shaft. I will appreciate any suggestions for freeing the Drive Gear without breaking it.

@Darby: The plastic cover is the drive gear that Harold and I have been talking about. It's all one piece. You will likely damage the drive gear getting it off of the shaft. As long as it doesn't damaged the shaft in the process you can get a new gear (pt 530350365).

My unit is in good shape except the catches on the spool are broken and i need to replace it, but I can't get to the bolt that holds it on. There's a plastic cover over it and I have no idea how to remove it. I've attached a picture. Any advice would be greatly appreciated

Wade, Yes, the trimmer is a VERY old unit, so your supposition that the shaft has corroded onto the drive gear is no tdoubt correct. Thanks for your attention to this matter.

If it won't budge then I have to think it's just seized onto the motor shaft. If the WD-40 didn't do anything, it's not likely that anything will. This looks to be a pretty old trimmer so it wouldn't surprise me that the shaft has corroded onto the drive gear. This may end up being the end of the trimmer as it will cost quite a bit to have the gear cut off the shaft.

Wade, I tried to remove the Drive Gear as if it has reverse threads, but, again, even with significant torque, I could not unscrew it. That was a good suggestion, however. In that regard, I called Sears Parts Direct to see if they could tell me whether those threads were reverse or not, but the person I spoke with had no such information. Also, I had made an effort to lubricate the shaft with WD40.

I believe on this model the drive gear will be reverse threaded so you will turn it to the right to unscrew it. If that's not the case, then it's just seized onto the motor shaft.

You may see if you can spray some penetrating oil up and onto the shaft (if you can get at it) and allow it to soak in before you attempt to remove it again.

Thank you for using Manage My Life!

Barbara,
Thanks for your response. I had previously reviewed the schematic and parts list, which are helpful.

These yard tools take a lot of use, so when it is time to take one apart to repair the parts can be locked up tight. I don't blame you for not wanting to force the part and possibly break it. While you wait for the expert to review your model if you need to check the schematics or parts list I attached to the first link below for your model. If you would like to take the trimmer to a service center for repair, you can use the second link below. I hope you can salvage the trimmer. Once you get a good one you want it to last.
