Hi Tom,

I just got done working on an 850T Transmission, and here is how it
works on it (I've never opened an Eldo 5 speed - and they are a bit
different from the T):


1. The worm drive goes in...I believe a washer goes in just before
this...but definitely not after.
2. The ball goes in.
3. The nut goes on.

On the T, there is one notch in the output shaft that is deeper than all
the others...that is the notch in which the ball needs to be set. Any
other notch and the ball will remain too high and the nut will run into
it.

Hope this helps!

Thanks for the confirm, Paul. I did in fact order an
additional 27mm nut so I'm good to go there. Any thoughts
on the output shaft nut issue - is there a washer there or
not?

Thanks, -tom

Yes you can use the same nut. It's available from MG
Cycle. I did this on my
74 and it works great. I also got a new star washer for
at the same time.

While putting tranny back together ('74 Eldo) I notice
that the output shaft nut (at the rear) seems to ride
directly on top of the speedo worm ball - is this really
normal - or should there be some kind of washer between
the nut and speedo worm? There wasn't one when I
disassembled it, but based on what else I've found
missing
from the PO - I don't trust that.

Also, w/o that "special" tool, I ground pegs on a socket
to use for putting the input hub nut on - I'm skeptical
I'm getting it tight enough. Can I use the same nut that
you use on the output shaft (27mm) - does it have enough
bearing surface? I'd really like to be able to put some
firmer torque on that input hub.

Thanks, -tom
