We are in the middle of a restoration and have our RAN-R1 at the trans shop being rebuilt.
It is almost done, but we need to replace the 2nd gear and we have not been able to locate one.
The smaller teeth (33 of them, which I believe engage they syncros) are what is worn on our original gear. These teeth should have nice angular faces coming to a point on the mid point of each tooth form.
From what I can determine, it must be from a RAN version, not a RAT or HEF.
Attached are some pics of the original gear and the thicker one from another 3.03 3 speed version.
The RAN gear has the narrower helical gear face.
The only difference between them is width of the helical face and the length of the inside bore.
The added length is on the helical gear side, not the cone/syncro side.
The cone/syncro sides seem to be dimensionally identical.
The dimensional differences are:
RAN 2nd GEAR SPECS:
25T Helical
33T Syncro
Gear face width: .906"
Length of Bore: 1.564"
RAT and/or HEF 2nd GEAR GEAR:
25T Helical
33T Syncro
Gear face width: 1.07"
Length of Bore: 1.704"
If anyone has a old RAN 3 speed and is willing to pull out the 2nd gear, I'd be interested in buying it. Or, if you are within driving distance or will be at the upcoming BYOB or any MEB event, I would take the entire trans if needed.
Thanks,
Drew
