Hello Wallypat

Yes, the clutch plate is incorporated into the transmission reduction for the
landroll. It's a simple cork-material friction plate lining.

Okay, so you're replacing the intermediate and final chain.

Remember that both of these chains will be adjusted together.
Loosening the "G" nuts enables the whole clutch plate assembly to be moved in
any direction, up, down, or sideways.

These are conventional nuts and bolts. Check that the threads are okay.
They should be secured tightly using a ring or open end spanner.
The chains should have a small amount of slack when tensioned.

Hope this helps.
