I urgently need the following torque specs for the Ford 7.3 liter engine:

1. Cylinder head bolts
2. Main bearings bolts
3. Connecting Rod bolts
4. Flywheel bolts
5. Cylinder head torque pattern
6. Crankshaft damper bolts

Send me a telephone number and I will call you today. My number is 268-725-1244 or 268-770-6919. I need this information today... Thanks

...Welcome to Ford Truck Enthusiasts!

…..See you on the boards.

 

All in ft-lb, unless noted...
Head step 1:65, step 2:85,step 3:105
Main 95
Rods step 1:52, step 2:80
Flywheel 89
Crankshaft 212

 

Um, how does one acheive 212 ft. lbs. of torque? Is that right for the crankshaft?! The harmonic balancer on the front of the engine? I have yet to see a wrench go that high.

 

you beat me back just after i wrote it all down... oh well good luck

 

Wasn't out to steal anyone's thunder; just looked at the timestamps.

 

With a torque mutiplier, that attaches to the torque wrench.

 

A lot of 1/2" drive torque wrenches go to 250 ft lbs. They usually start at around 50 if they go that high. I have aSnap- On that tops out at 250.

oh no not what i meant by any means just you where faster.

 

yup my snappy goes to 250 also

 

I see. Being more of a car guy I never noticed wreches that big. 200ft. lbs. will break off most bolts!

 

Axle nuts are sometimes torqued that high or even higher. Seems like the old air cooled VWs rear axle nuts were over 300 if my memory serves this morning.

I use mine a lot for lug nuts and front axle nuts on my front wheel drive cars, even though they are not torqued as high as 250, the extra length of the tool makes the job much easier.

If I had a wrench that went to 200 ft lbs, I wouldn't buy anything else to torque a crankshaft bolt or anything else that was held by a single bolt. I would just go a little tighter than the point where the wrench clicked.

To DaBigTow, many thanks dude. You did what scores could not do... Again, many thanks. I will be calling on you and your expertise if I have any more problems. You know your work and where to find the correct info. I too have a SnapOn torque wrench which tops out at 250. Car dudes will find those numbers unreal, but for heavy equipment mechanics, 400ft.lb or torque is all in a day's work. I will tell you how the vehicle runs..

Thanx
