Husqvarna 555 RXT Brushcutter - fuel cap is very very stiff to turn

Is it like the Stihl cap with an o ring?.

 

I bought a few spare o rings instead of the cap as it's usually the chip that damaged the seal, maybe go down a thickness or a softer NBR.

 

Not really.  I've just shared a picture of the old one.  Yes it has an o ring but it is very deep in there.  It feels like the threads are getting tight before it hits the o ring.  Maybe its not clear in the photo but there are threads on the wall of the cap and a white central core.

 

I've just checked, the diameter of the white core has clearance to the inside of the fuel tank neck, so it cant be binding.

 

Now that I am the proud owner of two of these caps, I suppose it wouldn't be a loss to butcher one of the caps.  I could file back the female threads of the cap and see of that made a difference?

I don't venture to the dark side of the brands 😉.

 

Sounds like the thread of the tank might be the issue, guess like all plastic it does distort over time, no doubt a new tank is a kings ransom?.

 

Just checked, about £50 so not bad.

I'd be tempted to run a knife around the outer edge of the fuel tank tip, as if you've overtightened it you may have rolled the edge.

Thanks.  Yes £60 - £80 (not sure about VAT or delivery) and quite a fiddle to replace.

 

As long as the distortion is even and circular, Id almost rather butcher the old cap to make it fit. If it leaks or still have to replace the fuel tank, then Ive not really wasted anything.

I'll check that aswell, thanks

 

Im still at work, but I've been thinking.  Maybe the plastic would re-mould with heat?  I could heat up the fuel tank thread with a hair dryer and screw on the cap to get a better fit.

Just checking, don't really want to reword the gunpowder treason rhyme with 42 instead.
