Installation & Troubleshooting v5.1

Rotate the crankshaft so that the

pistons are at top dead center

(TDC), the highest point in their

travel in the cylinders. Both

cylinders on an Airhead have the

same TDC crankshaft position.

The timing marks are stamped on

the flywheel and viewed through

the timing hole to the right of the

dip stick.

There is a groove stamped into the

left side of the timing hole. This

groove, NOT the center of the hole,

is used to align timing marks.

Rotate the engine by putting the transmission into 2

gear and bumping around the rear wheel.

This is preferred over using an Allen wrench in the alternator rotor bolt to turn the crankshaft as

this can wallow out the Allen bolt hole. Turn the crank until the OT dot, to the left of the “OT”

stamping on the flywheel, is exactly adjacent to the groove in the timing hole. (OT, in German, is

Oberer Totpunkt, literally the “top dead point”.) If having trouble turning the engine over, the

spark plugs can be removed but this isn’t usually necessary.

The apparent alignment

of the flywheel timing

marks with the groove on the

engine can vary by several

degrees by raising or lowering

your head a few inches.

This is due to the viewing angle

problem if your eyeball is not

exactly perpendicular to the

timing hole. The problem is

worse on R65s which have a 20

mm smaller diameter flywheel

that sits even farther from the

timing window.
