Remove the front pump assembly
Remove the push rods that are between the lugs on the brake bands and the brake band pistons and remove the B1 brake band. It is quite easy to pull out the B1 brake band and also the B1 brake drum.
I found that the B1 brake band was worn down to the metal – virtually no friction material left – consequently the B1 brake drum is badly damaged. The K1 clutch is inside this drum.
Here's a picture of the push rods on the B2 brake band.
You can now remove what they (sometimes bizarrely) call the B3 clutch pack. I guess this terminology is a throw back to the 722.1 that actually had a brake band – here reverse is controlled by a clutch. I'm surprised it isn't called the K3 clutch – hey ho let's go with the flow(?). Does anyone know why it has been named this way?
