Lincoln Posted Tuesday at 11:07 PM Share Posted Tuesday at 11:07 PM (edited) How do I access the crank shaft, to get a breaker bar on? Edited Wednesday at 01:40 AM by Lincoln Double posted... sorry! Link to comment Share on other sites More sharing options...
mat in tn Posted Wednesday at 02:13 AM Share Posted Wednesday at 02:13 AM the bottom belt pulley is the crankshaft pulley. use a 15/16 deep well socket or a short socket with a 2" extension and a breaker bar. turn engine clockwise as that's the rotation its intended. 4.9 is rather safe to turn either way but it's a good standard practice to only rotate an engine in its intended rotation. much more important with modern overhead cam engines.

Lincoln Posted Wednesday at 02:50 AM Author Share Posted Wednesday at 02:50 AM Thanks Mat. There’s no room. Am I supposed to remove the rad and fan housing first, to access the crank? Link to comment Share on other sites More sharing options...
mat in tn Posted Wednesday at 03:00 AM Share Posted Wednesday at 03:00 AM it is rather close but that's why I am specific about the sockets. in some cases, I have had to work from the top over the power steering pump but that feels very awkward also. my truck is lifted so it is easier from underneath.

viven44 Posted Wednesday at 03:23 AM Share Posted Wednesday at 03:23 AM (edited) I always use my flex head ratchet and the 15/16 deep socket from underneath. I usually have to fight the fan blades on every rotation, ensure the fan blades are pushed back every time. This was a challenge the very first time I tried this, but I'm so used to it now... And don't forget to remove the ratchet before starting the engine... don't ask how I know (DAHIK 😁)... well I'll just say. The times I had the ratchet opposing the engine rotation, luckily it just slung out thankfully with a bang. The times it was in the same direction, I just heard what looked like flexplate noise. I had assumed something was seriously wrong, the ratchet was just ratcheting the whole 20 minutes I was trying to debug the noise. Yes I wonder at those times if I should be doing mechanical work with my absent mindedness. Edited Wednesday at 03:24 AM by viven44 Link to comment Share on other sites More sharing options...

BigBrother-84 Posted Wednesday at 09:28 PM Share Posted Wednesday at 09:28 PM I don't have to manually crank my engine as Lincoln, but I'm curious: Did I read somewhere (Gary?) to pull out the plugs and pour a bit of oil in each cylinder, before attempting to turn the engine? What else than pulling off the plugs, in order to prepare such manual rotation? Unplug the battery? Put the tranny on neutral? Any other step?

mat in tn Posted yesterday at 12:57 AM Share Posted yesterday at 12:57 AM it is certainly different on the 4.9. the added length really crowds the fan shroud. its a bit easier on v8s. 1 Link to comment Share on other sites More sharing options...
