Just pop the sump off (15 mins max) undo the big-end bolts for # 3 and push the con rod up the bore and pull it out from the top - just mark which way round it was for re-fitting. Report back your findings!
Does anyone know the size of the nut that holds the crankshaft pully on
1 5/16"
have tried using a pair of pipe grippers
No chance with that method normally you undo that nut before you remove the engine as its a right so and so and it just tightens with use, what you will have to do is lock the flywheel a 2nd person with a crow bar may help and you will need a lump hammer to help shock it off it might take a few goes, one other thing you have remembered to knock back the tab washer.
