Thread: Number of teeth on HP fuel pump Disco 3

Use a length of pipe over the handle of your breaker bar with the crank locking pin fitted rather than use the starter to turn the crank. However a 3/4" breaker and socket may be preferable. You should be using a torque wrench to tighten the bolt so will need to do that by hand anyway.

Are you aware that a new crank bolt is required to be fitted?

Thanks Graeme & Justinc, I discovered the no keyway on the crank pulley when I got it off with a pneumatic rattle gun after I had the shaft locked with the timing tool & yes it could have been disastrous. I managed to lock the flex plate in another position as well by removing another inspection plug at the bottom of the bellhousing & gaining access to another hole in the flexplate thereby spreading the load. I was a little concerned with using the timing tool alone on the flex plate to lock it up with the tension of the crank bolt in case of damaging the flex plate or the tool.
