Drum Pulley Thread Stripped
Hi All,
I have stripped my Hotpoint BWM129 to change the bearings that have gone and got to the final point of getting the bolt out on the flywheel but it is a torx head and it has threaded. Any ideas to get this out so that I can change the bearings?
Can post a picture if it helps.
Thanks in advance.
Regards Stuart

Hotpoint BWM129 drum pulley bolt thread/Torx head stripped during bearing replacement
- The problem
- On a Hotpoint BWM129 washing machine, the drum bearings had failed and during dismantling to replace them, the final drum pulley/flywheel bolt could not be removed because the Torx head was damaged/stripped.
- Likely cause
- The pulley bolt head was damaged, preventing normal removal. The accepted reply also notes the possibility that the bolt may have sheared, but this was not confirmed.
- What fixed it
- Accepted advice was that if the bolt cannot be unscrewed it would normally need to be drilled out, and the thread may then need re-cutting with the appropriate tool. If the bolt has sheared but some of it is still protruding, a slot may sometimes be cut in it to remove it. Screw/bolt extractor tools were also mentioned as a possible option if the thread remains usable. The exact repair carried out was not confirmed.
- Checks to try
- Confirmed model: Hotpoint BWM129
- Bearings reported as failed
- Pulley/flywheel bolt identified as Torx head
- Bolt head reported stripped/damaged, preventing removal
- Parts or tools mentioned
- drill
- thread re-cutting tool
- screw/bolt extractor tools
- hacksaw
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

With a bolt unable to be unscrewed it would normally have to be drilled out and often the thread re-cut with an appropriate tool. Very tricky and time consuming. If you mean it's sheered off leaving the shaft inside with no means of unscrewing the same apples except if the thread is still ok there are tools available that are supposed to undo screws and bolts when the head has sheered off or the head become damaged. If anything is standing proud you can sometimes hacksaw a small slot to use to undo it.
