Locking the flywheel/crankshaft

[eternaloptimist]

It's a late M59 1.6HDi. Registered Jan 2008. I said 1.6 HDi in my first post and described it as a late Mk2.

Anyhow, some progress. I know it's important to pin the diesel pump on a non high pressure system, but I've seen conflicting reports on the need to do it for this engine. After a bit more work, I've found my pump is one tooth advanced, that's why I couldn't pin it. No problem, not critical, easy to fix.

However, the flywheel's a different matter. After a bit more fiddling, I managed to get the pin over the top of the exhaust flexi and started looking for the locking hole. When the crank and cam are pinned, the pin for the flywheel doesn't fit. Laying under the car with one finger pressing on the end of the pin as I contort myself to move the ratchet with my right arm, there are two holes where the pin fits, 180 deg apart. Neither line up with the pin positions on the crank pulley, they're about 10 to 15 degrees off.

I know I can ignore the flywheel pin for the cam belt change alone, but I'll lose the pinning of the crank when I take the crank timing belt pulley off to replace the worn crank oil seal.

If I pin the crank and cam and remove the belt and water pump, then unpin the crank, turn it back approx 10 to 15 degrees to pin it at the flywheel, remove the crank woodruff and pulley, do the seal, refit woodruff, pulley, remove the flywheel pin then turn the crank back so it's pinned, I'm not going to have a problem am I?

What am I missing?
