Italian Work at Sheddington

Work on the Moto Guzzi at Sheddington

There was a small oil leak from the left cylinder area of the Moto Guzzi, it appeared to be coming from the cylinder head.

On Friday we decided to replace the head gasket.

This is not a tough job on this bike, you don't even need to remove the tank.

Getting the carburetor moved out of the way is a bit of a trick but once that is done the rest is straightforward.

With the head was removed, the location of the leak was apparent, it was on the top left in this picture.

The top of the cylinder was cleaned and prepared for the new gasket.

Next the head was cleaned and inspected.

There were a couple of very minor surface imperfections, but nothing to worry about.

The new gasket was installed.

Then it was just a matter of replacing the bits we had just removed.

On this arrangement there are four studs of one size and a fifth smaller stud.

Consequently there are two torque values for the head studs.

With every thing back together it was time for the test.

The bike started up right away and now there is no oil leak.

In 500 miles we'll go back and recheck the torque on the studs.
