How to successfully remove a staked base valve nut?


Recommended Posts

Do any of you have any successful methods for undoing the stake on a base valve or mid valve thread and still keeping full functionality of the assembly? I'm concerned about destructive disassembly practices and not being able to get parts!

2014 500 EXC, btw...

I've seen lots of versions of this, and it's been fine, but this is the most severe stake I've seen and I can't really afford to get it wrong. The midvalve tap is staked the same.

Then use a file, I do a few sets of these a week and never had a problem but there is a first time for everything.

be lucky to find a file that fine, they are m6x.50

0.50? Oh...it's a KTM.

One of the universal thread tools may work (two examples below) but you're probably better off doing it the old-fashioned way (e.g., file by hand).

First MV nut came off really nice after flat filing the sides of the stake. No idea if I'll get as lucky on all four stakes.

Does everyone use blue loctite on these threads? I always have but just wondered if there was a chemical reason not to...
