Under supervision, a young nurse has a go at explaining the BMW M47 that is on a workshop bench

I found the explanation of locking the flywheel very clear and most helpful.

Would anyone know whether any shaft or pin of the correct diameter and length can be used if taking the crank pulley off?

I assume the locking pin tool is aimed at securely holding things in place for when working on the timing.

Ed this is only for changing the timing chain, which on the M47 diesels is very rare indeed, if the chain needs changing then something has gone really wrong.

To remove the crank pulley there is a special tool which i doubt many would have, the tool is very costly for the genuine tool.

Some people just use a gun but i have seen things go wrong like chain jumps out of timing, so always best to use the proper tool.

Small after market holding to can be bought off ebay which do work.

Thanks Steve, I am learning more on the M47. At 12 minutes 55 seconds into this youtube (working on the M47 Freelander) just like the young nurse, he suggests locking the crank at the flywheel as a way to remove and replace the High Pressure diesel pump. https://www.youtube.com/watch?v=bw6nOxs3PG4

Hi Ed
Yes always best to remove the starter motor and lock the flywheel when removing the HPFP which also has a special tool, you also need a 17mm allen key socket to remove the cap first, or use a bolt with an 17mm head and lock some nuts on it so you can turn and remove the cap that way.

All the above is only done after you have removed the starter motor, locked the fly wheel, raised the engine a little and removed the top mount etc.
