Is there 2 types of B4 outdrive?
 

Hey guys. Im trying to build a car based around B4 parts, but cant figure this out. I have a ball diff right here looking at me that I have been told is out of a b4/c4.1, is has a wider part and flange each side for the bearing, this design

But I'm also getting a lot of images of a smooth design with no flanges and no widening, this design

Can anyone tell me which one the right one is/the newer or older design? Thanks

I should know this already!
Took me a few minutes !
Are both of those pics the same part number?

The top pic are the latest ones in the b4.2 nd b4.1 kits

The bottom pic look like there the older b4 items with no big lip on them

Hey,

The outdrive 7668 & 7667 (left and right) are the old style outdrives, they take inperial bearings, 3/8 x 5/8.
Used on the B4 line.

The 9852 are the newer outdrives, these come with the B4.1 / B4.2, used in the C4.1 / C4.2, these use metric bearings 10 x 16mm.

Huge help thanks guys, was the gearbox re-designed to accommodate the difference between between the two does anyone know?

Yep,

The B4 / B4.1 & B4.2 gear boxes are different, but easy to tell apart.

The old B4 gear box is narrow compared to the B4.1 /B4. 2 gear box.
The B4.1 / B4.2 gear box is wider so it can take the gear diff.

You also need the newer rear t-plate for the B4.1 / B4.2, gearbox is wider, so t-plate has a bigger gap for the gearbox to sit into.

Where do the FT lightweight outdrives AS1766 fit into all this ? Ive just fitted them to my 4.1 gear box.... the 4.2 or SC10 rear plate is only needed for the geared box which I have also fitted to a B4.1 ..
