Locknuts and Spanners for Guzzi Transmissions by Tom Halchuk

I had my V11 Sport Transmission apart.  The transmission was leaking from the seams from the last 4 times the hack mechanic had it apart.There werer a few things wrong that I found.  But I'll skip that and cut tothe point.

There are four locknuts & lockwashers in the V11 Sport Transmission.  They hold the shafts against the bearings and the clutch spline on the main shaft.I replaced them.  Sourcing from Guzzi would take too long.  After talking
with Mark Etheridge he gave me a size for the Eldo 5 speed. That is where my search began. I finally got a set from Eastern Bearing supply. BUT that took a week.  I decided to find a quicker source.  This is what I found.

All Loop, Tonti and Spline frame transmissions use locknuts and lockwashers. I found the manufacturer of locknuts and lock washers in Central Falls,Rhode Island.  They will ship same day and the cost is about $2 each.
