Honda Strimmer Advice Needed Please

[moosic]

Hello everyone, new to the forums so go easy on me! I have a Honda UMK42U Strimmer / Brushcutter. I changed the brushcutter head over to the strimmer head without the bloody spacer now i can't get the head off. Anyone have any ideas how to go about it please? Feel like such an idiot, hope someone could help. Thank you.

Fillter wrench and a pin into the locking hole ,,remember its opposite hand thread

 

[moosic]

Sorry that should be Honda UMK425E

 

[moosic]

Thank Lincs Lass I am putting the pin in there and turning it clockwise by hand, doesn't seem to do anything though, apart from turning!

 

[moosic]

Actaully when i put the pin in there, it doesn't stop the head from turning.

 

[Lincs Lass]

There should be a knotch in the drive for a pin to drop in ,,its the only way to stop it free spinning

The notch to lock it will probably be on the spacer that’s left out so you may have to remove gearbox and hold the pinion while turning the head, LH thread

Which looks like part 13

Yeah, it is part 13 on the space is where the notch is. Thank you both. No otherway to do it then apart from remove gearbox?

Easy job to do? Never done it before let alone know what the pinion does!

If the spool is only on finger tight and not been run then as Tony1989 says ,take the head of the drive shaft ,wedge the end of the drive and pray the spool comes of

Gearbox is easy, normally a couple of Allen screws and it slides off, some have a hexagon drive shaft so you may be able to hold it with an Allen key

The gear head is only clamped onto the shaft ,it should come of with a gentle tap ,nothing heavy as its ally ,

Not really got anywhere with this today, got the gear head off but can't see a way forward. The thread has definitely tightened with the strim head.

 

[Tony1989]

What shape is the end of the driveshaft?

 

[Rs chunk]

Will the drive shaft up the middle of the tube slide out? If so engaged it in the gearbox and clamp a mole grips too it then that will stop it from turning

 

[moosic]

Ok, done it in the end by sticking the allen key into the drivehead. The shape of the shaft was a slight square and the allen key fitted right in then just turned it off. Thanks for all the help on this everyone, been doing my head in - from now on will always remember the spacer!
