3 speed to 4 speed

[breezer]

Okay, I'm still a little confused about this... I've got a PK50 4 speed gearbox to go into V100 cases.

Do I use the pk50 output shaft or the V100 output shaft?

Or are all the output shafts the same?

Also I don't understand the difference between square & round cruciforms - can I use the cruciform from the PK?
Are the cruciforms mated to the shaft or gears or cases?

Apologies for all the questions.

Swap the PK 'box straight across Jim.

i think the shafts are all the same, but pk & v series cruciforms are slighty different (ones a little longer) so you will need to use a pk cruciform with pk gears.

Cheers, glad it was the "easy" answer!

What about cranks? Can I put a 20/20 crank in the v100? Is it as easy as getting a different oil seal?

that should be ok, with correct oil seal
