Monza 160 gearbox

[DougW]

I am in the process of putting a 1966 Monza Jr. engine back together. All the transmission gears are on the splines in the correct order, as I never removed when I took the engine apart. It appears to me that the shifting drum and the forks can really only fit back into the gears one way. (is that the case?) I seem to be able to manually shift through all the gears as long as I am turning the shafts. Does the gearbox need to be in neutral when I put it back together, and if so, how do I know what is neutral and not just in-between gears? Any and all info is appreciated. -Doug

____ I'd assume so but, I've never checked to see if it was at all possible to do otherwise.



" I seem to be able to manually shift through all the gears as long as I am turning the shafts. "

____ That's as is expected, because otherwise there's a chance that the possible alignment-arrangements of some of the dog-sets will happen to collide atop one-another rather than engage-together (unless the dog arrangements are-not kept stagnant).



" Does the gearbox need to be in neutral when I put it back together, "

____ While that's the preferred arrangement, it really ought-not be necessary.



" how do I know what is neutral and not just in-between gears? "

____ Take-note of the near-vertical position of the female-slot in the driver-shaft of the shifter-box when it's set in it's neutral-position, and-then see to it that the corresponding male shaft-tip of the selector-drum is rotated into that same near-vertical position.
(Sorry if that's so simplistic it causes you to think the common-thought: 'Now why didn't I think of that ?'.)
