Dear Gearheads,
I am rebuilding the transmission for my TR 250. I have rebuilt
engines before so I am not having a VERY difficult time, but it is
a new learning experience all the same. As I was test fitting/playing
around with the gears, engagement hubs, and synchro rings, I thought
I would be able to understand the all inner workings. I figured out
everything except those d***n synchros!
The theory I have is that as the engagement hub outer collar is slid
tow-
ards the gear, it engages the synchro, then as it travels further
(during
the act of shifting) it slides the synchro towards the gear.
Does This act of sliding it towards the gear cause the inner cone of
the synchro to rub (for lack of a better term) the gear, slowing it
down,
slowing those little teeth so the engagement hub outer collar can mesh
more smoothly? Am I to understand that all 110 horse power (if it runs
that well) of the engine is transmitted (now I see why they call it
that)
at this point through those tiny little teeth that the engagement hub
hooks up to? Then why are the other teeth on the gears so large? To
acheive
a large outside diameter on the gear (for correct ratio)?
I would appreciate any answers anybody can give me.
And I apologize beforehand if I start one of those neverending threads,
but
I just gotta know....

so I won't ask that....
