As i want to replace the points distributor by an electronic one based on the Range Rover design, i at the same time want to replace the standard oil pump on my P5B coupe by a larger volume pump with a male oil pump shaft. Then i have on my 2 Rovers and my MGB V8 identical interchangeable ignition systems and i only need 1 spare then.
I have removed a few pulley bolt but the engines were not in the car and then i block the flywheel.
What is the method when the engine is in the car. Searched the internet and found some options: 1 using the starter motor and a breaker bar,2 impact wrench, 3 removing starter motor and then with a large screwdriver and block the flywheel.
option 1 is no option, option 2 will work but i still need to find a method for tightening it and i don't think impact tools have a reliable torque setting. Option 3 looks the best option although removing the stater motor is no fun job.
Would removing the plate (looks like half of a disc) which covers the lower part of the bell housing be a solution?
Any thoughts?
Thanks
Peter

Others will advise against but I stuck mine in park and used an air wrench. It came undone first try!
The park pawl is a known weak spot but I figured the shock was sudden and not prolonged.
Best of luck! - a starter is very heavy and always seems to hit me in the face!

Remove the Bellhousing plate, insert a screwdriver between the teeth of the flex plate and slowly rotate till you have it tight against the bottom of the engine. Crack the pulley bolt then rotate back to release the screwdriver.
Caution - use one of an appropriate size - quite tight between teeth - and ensure you have the screwdriver aligned, horizontal and against the block.
Use an extension on your breaker bar - but be careful - you do not want to damage or break your flexplate teeth - nor the screwdriver for that matter.
Given the size of the diameter of the plate versus the pulley bolt I don't believe there is a huge amount of pressure placed on it. I've done this many times with no obvious damage when I haven't wanted to remove the sump.

Phil has spoken, nevertheless I would strongly advise using an air tool with a decent pressure (90 PSI ) and 12cfm. There is no need to block the engine or put it in park. The inertia of the crank is quite enough to work against.
Obviously make sure you are turning it the right way and the locking tab is fully flattened.

I would try option 1 first Peter it worked for me jus make sure you have a good tight fitting socket and a friends extra pair of hands helps  |

Between a 3.5, a 3.5 'S', a 3.9 and a 4.6 I haven't seen a locking tab yet inside a crank pulley. Am I missing something here?

Thanks all for the reply's
The starter motor option and air wrench may work but how do you tighten the nut again? I believe and air wrench isn't very accurate when tightening the bolt again.
I will remove the bell housing plate and use the screwdriver option or make a locking device. I need to wait for the timing cover gasket and oil seal arrive as i didn't notice its better to remove the timing cover to fit the high volume oil pump
Wajowen: looking at the end of your reply, i see, you have an interesting pair of Rovers with the bigger engines and the ZF box. Did you built these yourself?
