gear box nuts

I saw a thread a year or two ago, which I now cannot find, in spite of trying to save it, where you could lock the two shafts together by selecting two gears at once. This held the shafts solid to remove the two end nuts.
It was a 915 box, but I presume the same applies for the 930?
The thread was by McCale I think, and started with "I can't shift into first.."
Tried every search - no luck.
Anyone know how to lock these gears - I've forgotten how I did it.
Thanks
Alan

Found it by tracking back thru my own postings - it is Cale.
You select Reverse and any foward gear. On the 930 (don't remember this issue on 915) I had to lock the reverse gear in place with a keeper using two of the housing studs. The big end nut was on so tight the gear wanted to ride out over the teeth.

On the 915 I think you just select a gear and then you also move the 5th gear slider to select 5th gear as well IIRC.

locking gears

an old school method is to place a towel between gears ,close to bearings to prevent shaft defection and turn nuts slowly shafts will lock up.towels work better than rags..an old timer showed me this trick and we use it all the time.murf

That one is well worth remembering.
Locking R and a fwd gear certainly worked but it was necessary on the 930 to tie the R gear in place - but I had removed the little selector fork for it.
If that is left in place initially, there may be no issues.

For removal, is there any down side to straightening the punch mark and using an impact wrench? If there is a problem I must admit Im a hack, but it worked for me. For reinstallation I put the trans back on the motor and held the crank pulley with a wrench while tightening the nuts to spec- It was defenatly a relief when I torqued the nuts and the origonal punch marks lined up. that was cool

there are plenty of people who have used the impact driver. But given that you can lock the gears up solid, I think this is a less brutal approach (I prefer to use impact wrench as last resort). And you can use this method to tighten (torque) and loosen. The loading on the gears using this method (100 or so ft/lb) would be far less than normal road use.
