New Oil Cap for Husky 346xp too tight

[alexm]

Hi there,

 

I just bought new oil and fuel caps for my 346xp. They are genuine Husqvarna, the new type for the 550xp but they are meant to fit 346xp as well. I got the large cap for the fuel and the small cap for the oil. The fuel cap fits no problem but the oil cap is too tight to fit.

 

Has anyone else had this problem? Would widening the hole work?

 

Cheers,

 

Alex

I would go easy on widening the hole as you could just cock up the mechanism altogether. The only time I have had issues like this is when the thread paint has been softened by solvent. I haven't swapped out caps like this and it is usually the fuel tank plastic that makes the screw caps tighter.

Yeah, the thing is though the hole in the oil tank is metal!

The existing cap gets tighter on its own (it's a common problem, either the plastic cap expands somehow, or vibration tightens it) so you need a screw driver to release it. I thought replacing the cap with the flip up handle would be the way to go.... but I can't even fit it!

Just checked, the 550 cap wont fit the 346, the initial part of the cap is too large for the oil hole although the 346 cap seems to fit the 550 but wouldn't recommend any modification of the alloy 346 casting to accept the 550 cap.
