1972 Norton 750 Commando Rebuild Page 4
I had to install some new head studs on the cylinders and, in preparation for the head gasket, some Coppercoat gasket sealer. This isn't normal for head gaskets but a little goes around the pushrod tunnels as the gasket tends to blow out here first.
he head gasket goes on and the pushrods are put into the tops of the lifters.
A last check is made as the head goes down to see that everything is aligned and ready to go.
As the cylinders go down the tops of the pushrods have to be matched up to the rocker arms.
I use this anti seize compound on just about everything that bolts together. It is especially important if you are using stainless fasteners, as I am, so that the mix of cast iron, and aluminum parts does not gall and stick together. It also helps get the same torque on all the fasteners.
The head gets pulled down against the valve springs using a central head bolt.
These barrelnuts go up through the bottom of the cylinder fins and connect to studs in the head. Older Norton engines have no bolts that go from the head to the crankcase.
The location of the barrel nuts.
A nut goes between the cylinders in the back on a third head stud. This one is a mother to tighten. The wrench gets only about an eighth of a turn each time.
The engine itself is now complete. Here I am buffing the timing case and re-painting the logo. I love the look of this old engine. The timing case has always looked almost organic when it is in the bike.
