G'day Folks,
I can probably work this out myself (and will do so if necessary) but was wondering if others have done this before.
I have my engine on a stand - no flywheel adapter / housing fitted - no flywheel fitted. I don't really want to lift the <BLEEP>ing engine of the stand yet again to fit the flywheel at this stage just to set up the camshaft timing. No head is fitted (and of course this means no valves or tappets or the rest of the malarkey).
Whilst I expect I'll get swamped by "why not wait until later when everything is all fitted" comments I'd like to time the camshaft in this "lower block" state.
It seems to me to be the logical thing to do at this time with a push rod engine like this old beast.
So camshaft is fitted and the cam followers are in place: It is possible to measure with a DTI the rise and fall of the exhaust camshaft lobe on #1 cylinder.
Pistons are fitted: It is possible to measure TDC
Flywheel is off: But you can measure (by counting teeth) on the ring gear the position of the "EP" - exhaust peak position with respect to TDC and convert this to degrees
So it should be easy enough to work out where the camshaft position should be set in relation to the crankshaft position - right?
Clear as mud?
If it is not as clear as mud and you understand what I mean and you've done this before I'd like to know the values you calculated so I can check the ones I'm probably going to have to calculate myself.
(If there's actually a Land Rover routine for doing it this way I'd like to know about it as it isn't covered in the Green Book. It wouldn't surprise me if they were set up at the factory in the way I'm suggesting as waiting for the head and the rest of the valve gear and then setting up the timing is potentially asking the valves to meet the pistons!)
