FINDInG TDC IN an M42

[rjcaptsean]

On mine it pointed to a small notch on the pulley portion. The "missing tooth" area is almost at the 12 o'clock position and the small notch on the pulley tooth was pointing to the arrow.

Of course I don't have mine in and running yet...

found it, thanks.. the notch itself is on a toot.

fiftytakedowns (or someone), do you happen to have a picture of this "notch?" I have my timing case apart right now to replace a dead idler sprocket, and I will be pulling the timing case to re-seal the rear gasket. I used the "screwdriver in a hole" trick last time, but would prefer something more external.

Is the "notch" on the crankshaft snout, the crank sprocket that drives the chain, the flange that mounts on the crank, or the harmonic balancer? I have an M20 flywheel in there, so the original option is out.

Wish this was a little better pic..

The notch on the pulley is sort of hard to spot.
I used a silver paint pen on the arrow found on oil filter canister – and a small paint dab on the pulley notch.
