RR T2
« on: 01.06. 2020 23:01 »
I have come across a RRT2 gearbox. It has the top plunger location so I guess it is genuine.  It has SC  stamped under the RRT2. Idid not know they made scrambles RRT2.

Neither did I know that. I suspect that most of us on this forum will be surprised.

Something not quite right there as a scrambles box would not have a reverse gear shift pattern.

The shells are all the same on these special gearboxes. The cluster inside is the main thing,you can count the teeth to be sure whats inside. The only different are rollerbearings the RRT2 has also rollers at the sleevegear. The others only at the layshaft.

mine has drillings top and bottom with a big plug in the bottom hole, it has one needle roller and a bush in the sleeve gear and two needle rollers for layshaft, when I have put the clutch back together with the correct parts if I don't get on with the rrt2 it will be taken back out. not really had enough miles yet because of the dodgy miss matched parts triumph clutch

There was an SCT2 scrambles box used on only the 1957 Spitfire.

My words
you can be lucky if its a Scrambler gearbox, its much more better with the gearing than the  Racing box.
I use in two bike the Scrambler box and it is fantastic.

It is stamped RRT2  with faint SC under the  RRT2 stamping. I am stripping the box for clean and service and I will post results.

And once again one might ask weather the box & the bike left the factory together 70 years ago. ?

Hi
Post photos of the box and any numbers you find stamped on it,
check the main case and sandwich plate for changed numbers, there are other differences internally too
There are hundreds of "forged" RRT2's out there

Hi TC,
That is an SCT box that would have needle rollers on the layshaft only
The  number on the back of the sandwich plate and the main case should be over stamped where the cast numbers were, and a steel blanking plug at the end of the layshaft  bearing under the sprocket bearing.
