How To Fix a Brushcutter Trimmer Head Gearbox on a Honda UMK

Thanks for the great turorial! I have a stuck greasing bolt on the same type of head: how could I get it out without damage?

I have a problem with gear being engaged fully when I start the brush cutter. Usually it doesn't spin until you press the throttle. Where is the problem

Thanks for sharing this. I’ve just took the gear box head off my brush cutter and the shaft seems stuck in there as well. I was under the impression that the shafts just pushed into the gearbox assembly?

What is the use of pulling it apart if you can’t find where to buy the gears from??

Does not tell us where to buy the bevel gears. I’ve searched high and low and cannot find six tooth splined bevel gears anywhere!!!!

Where did you buy the gears from??

Would have been helpful to show how exactly you pulled it apart.

Great Video, Thanks. Could you confirm if the bearings you specified were for the Honda 435 UMK or 425 UMK?

Thank you so much! Have you a webside to buy the pieces please ? Gwen from France ! 🙂

The annoyance in your voice is epic broski

Simple, waffle free, to the point and clear, well done and thank you. CV grease is my go to for anything non specific, particularly on motorcycles, I wonder if any of the big suppliers like SimplyBearings might stock the seal and seal spool.
