Default Turning Engine by Hand

Hi All,

I'm having some trouble trying to turn the engine on my 2002 Ranger Edge 3.0L (non flex fuel model, automatic transmission) by hand. I tried turning the crankshaft pulley clockwise with the spark plugs on today, and was only able to get it to turn a very small amount. So I removed the spark plugs and tried it again, but couldn't get it to rotate at all. I was using a 10" long ratchet wrench and applied a pretty good amount of force. Does it take a really large amount of force to turn the engine? If so, would an 18" long wrench do the trick? Both times that I tried turning the engine, I had the car in park (does it need to be in neutral?).

Also, does anyone happen to know at what torque value the crankshaft pulley bolt is set to? Since I would need to buy a longer wrench if one is needed, I was thinking of just buying a cheap 1/2" drive torque wrench to turn the crankshaft pulley since I saw one for cheap and thought it might not be a bad way to make sure I don't accidentally overtighten the crankshaft pulley bolt when trying to turn the engine.

Thanks for the help.

Don't know the answer to your question but don't use a torque wrench for breaking things loose you can mess up the mechanism and when you goto do somthing by torque specs it would be off. You can always just get a cheater bar for your ratchet.

Need some more history on the engine, did it suddenly stop running, and wouldn't turn with the starter, did you have oil pressure, the cam sycro may have went out and cooked the lower end. With the plugs out, it should turn with a 3/8 ratchet easy.

I'd think you'd need to put the tranny in neutral, but I know pretty much nothing about auto transmissions.

I know I used maybe an 18" breaker bar to turn mine over with no plugs, and it didn't take too much force.

With an auto trans, it makes no difference weather its in park, natural, or any of the gears.

Thanks all for the replies. The truck was running before; the cam synch is going bad though (and is actually what I'm trying to replace), but the truck was running before starting the work and was just making the chirping noise. I ended up buying the alignment tool to swap out the cam synch just to be on the safe side, which is why I'm trying to get the engine to TDC (I need to replace the spark plugs in the truck anyways, so I figured I'd just use the alignment tool method since I'd be going through all the work of pulling out the spark plugs anyways).

Thanks again.

Will it turn over by hand if you take the belt off?

Haven't tried taking the belt off; is that a good next step? This is my first time working on a car, so taking the belt off sounds like it's above my skill level, but I can read up on it a see if it's something I might be able to do if necessary.

it's super easy, you might want to drain the blinker fluid first though...

I just did this with a rubber strap wrench around the crank shaft pulley. I removed the belt and the spark plugs. Then I had my son hold the clutch in. With that done, it was quite easy to rotate the engine.

The belt really shouldn't make it much harder to turn over unless you've got a seized pulley or a bad AC clutch or something like that. It's easy enough to remove the belt just to eliminate that as a possibility though.

Thanks again all. I'll give it one more shot this weekend with the belt on, and if I don't have any luck, I'll pull the belt off. Thanks again.
