Due to hydrolock, I am opening the case to get to the broken idler gear.  You have to unstake a couple nuts.  Can anyone who has done this tell me how they did it?  Then manual says to grind or cut that part of the nut, but it seems there has to be a better way.

The only nut I know that is stacked, is the one for the clutch pack basket. A long punch, to knock out the dimple a little, and the nut comes off.

After the basket comes out, you can then remove the rear case cover.

Do you have the sockets?

The last post I made at the bottom has the socket sizes and links.

Thanks, Gordonv, the links to the two larger sockets say they are unavailable.  I have ordered both sizes I need off eBay - just hoping they are going to be long enough - will find out in a few days!  I was just at a stopping point with the staked nut.  I didn't want to do anything wrong or stupid!

"Underneath is a 31mm nut that is staked down (peened).  I used a 1 1/4 socket and the impact wrench to spin that bad boy off.  It's torqued on to about 97 ft lbs, so you either need to build or buy the hold-this-sucker-in-place-while-I-tear-a-bicep-using-a-breaker-bar special tool, or use an impact wrench."

When I did my clutch I just used an airgun and the nut came right off.
During install u have to stake it back down again.
all of this is in the service manual. go to Dag's norway site to download for free.

I have the manual - it says to grind or cut where it is peened.  I thought there was an easier way.  Seems from what you say that nothing is necessary - just spin it off?  Some people use small punches to relieve the staking, but if that is not necessary, that makes it even easier!

I've not taken the clutch off, so take this with a grain of salt. I've read many posts of it being done and the method CA described is the way they all do it.  cooldude

If you can't pry the lip on the  nut up then I drill the nut that seems to work the best for me.

You are referring to where the nut has been staked, thus removing the indent/staked portion?

What size drill, like a real small one to get between nut/shaft, or a VERY large one to sort of ream it away?

plenty of similar reports out there most use an air gun. many suggest some extra lubrication on threads first.
one poster states it will un-stake itself due to being a soft metal. When I did mine that is what happened using an air gun.

If you don't get the tab raised up on the nut and you use and impact gun you run the risk of damaging the treads

Never been into the Valk so not familiar with the stake setup.
On other transmissions the shaft is grooved and the nut  peened into the groove.
I use a fine chisel or punch with a taper ground into it to go under the nut and force the staked section away from the shaft.
