638 is not a thread locker it's for holding/bonding flat cylindrical components i.e. gears on shafts.

The washer is what is supposed to stop the nut undoing, not the Loctite. The use of Loctite is a get around for a design flaw, to which there are two modifications, one redesigned nut, two redesigned (replacement) lay shaft. Just the nut can work, but this is dependant on thread damage to the shaft. Using just Loctite there's a high chance the nut will undo, using a lock/washer less so, but it can still undo, more so using 243 what was known as nut lock.
I would suggest you search on the site for sprocket nut and see what can happen. They don't just undo and fall off they destroy the thread on the lay shaft and the sprocket cover. Replacing the lay shaft is a engine out split the casing job, plus the cost of the shaft, which the last I looked is no longer available new.
I wouldn't advise using 243 or 638 but it's your choice, hopefully you'll get away with it.
