V8-60 torque settings

[john hamilton]

Can someone provide factory torques for the heads, intake and exhaust manifolds and the front cover plate for this little engine? Thanks.

Those are big engine specs...bolt sizes are bigger.
The most important one to research is the ROD spec, as the big engine one is waaay too high. Ford published very little on this, and some published charts for the big engine falsely imply that they are correct for 60. Specs probably never existed for cover and manifold.
Right specs on old barn are not now accessible...need to wake up one of the 60 experts on here.

[john hamilton]

The responses say that torque infor for the V8-60 isn't available except maybe from an expert. Any out there? This is obviously a wide-spread problem. Thanks.

[Bruce Lancaster]

There surely has to be a factory source, but I haven't seen it...the engine hardly exists in the later bulletins.
I have no 60 owner's manual...maybe those numbers in the 1937 intro specs in the early set of bulletins. Will look there, an obvious source I have not checked. Early Motor's manuals, too. There is also a recent book of 60 technology...lost the link. Writer was on here. Looked very good.
The dangerous thing is that the headings on some of the available flathead charts strongly suggest that the 85 specs also cover the 60...

Got these numbers from a shop manual:

14 MM. Castton Head 24-28 288-336

14 MM. Aluminum Head 20-24 240-288

The first pair of numbers is in Lb-Ft the second in Lb-in. For the 60 alum heads only one value is given, no range.

I have not come across the numbers for the timing cover. You can get the whole series of shop manuals and TSBs on CD from Detriot Iron Information Systems or through an early Ford parts supplier.

Those are the 221-239 numbers as listed in the overhaul manual, NOT 60. 60 fasteners are smaller, and those are high, especially on the rods which have tiny bolts.
I'll delve around at home...numbers must be in something!

I replied to John Hamilton's post with a PM citing the lack of torque info in the Ford '37 -'38 technical pubs. I assemble my 60s using the specs from a French Ford Vedette manual. Hoop can verify that the engine in my '31 RPU is a strong runner and non-leaker using these specs. As everyone knows, the Vedette engine was the postwar European version of the US 60. Measurements in ft lbs translated from m kg, therefore the decimals:

Main bearing caps 50.6 to 54.2
Intake manifold 13.0 to 14.4
Exhaust manifold 13.0 to 14.4
Water pump 13.0 to 14.4 (does not apply to the US 60 - the pump bodies screw into the front cover)
Oil pump cover to op body 5.06 to 5.78
Fan to pulley 13.7 to 15.9
Connecting rod caps 21.7 to 23.1
Cylinder head nuts 28.9 to 30.3 (these were aluminum heads)
Flywheel to crankshaft 75.9 to 84.6
Clutch pressure plate to flywheel 10.8 to 12.3
Transmission to cylinder block 18.1 to 21.7

Here's a scan of that page. Also includes engine clearances.

Torque specs for the V8-60 are very elusive. The 1938 V8-60 owners manual gives no torque specs. There is an SB giving the torque for V8-60 aluminum heads at 30 Ft.Lbs. and all cast iron at 50 Ft.Lbs. The 11 th edition of the Motors Manual '35-48 has a Ford chart that gives a broad general torque range that is not really close.It groups rod torque at 35-40 for castle nuts and 40-45 for self locking. It groups main torque as 75-8- for castle and 80-90 for self locking. It groups both engines in the same class. Richard Willim's V8-60 book has a copy of the Simca torque chart which is probably the closest reference there is for this engine. He does show 25-28 Ft.Lbs for the rods in the section concerning them but otherwise pretty much you have to refer to the chart. I would suggest for most non critical bolts to use standard torque reference by size.

I've built several "60"'s and run them in my midget for 16 years. Haven't lost one yet: rods = 24 ft Lbs; mains = 60 ft lbs; aluminum (racing) heads = 35 ft lbs. I hope this helps...

Can't thank you enough. The engine runs OK but needs to be taken apart and completely cleaned. Couldn't have done that without your help.

My engine powers a 1937 Hobart welder and is stock except for a bronze adaptor for a Ford 1-barrel from a Ford 6.

Bumping an old thread as I am ready to assemble a 1940 v8-60. From the posts above we have the range for rods at a low of 22 (Greg, Hi Greg!) and up to 28 (Williams book) and mains at 50-60. Anyone have any additional info/recommendations? TIA

[Mike in AZ]

here's a link to MacVP's website showing a few specs.....perhaps you could start a new thread for what specs you're looking for.....Mike

[Blowby]

Thanks Mike, wow, 65 for mains. 40-45 for aluminum heads sounds high too, I've been using 30-35. At least the general consensus for rods is around 25. I really just need the main and rods, the rest I've done before. Paul

[Mike in AZ]

depends on where you get the info, i guess....reading George McNicholl's "how to build classic hot rod V-8 engines" mains torqued to 80 ft-lbs...40 ft-lbs on rod nuts....30 ft-lbs for aluminum heads......cast-iron front gear cover 15 ft-lbs...intake 25 ft-lbs...oil pan 15 ft-lbs.....good luck....Mike

[Bob C]

From the book by Richard Willim "The V8-60" Mains 65, Rods 25, Aluminum Heads 42.

Well, looks like you can use whatever you want, no two answers the same! I would use a torque chart/table based on the bolt size, thread type and bolt material. In most cases torque values are based on the fasteners. At the least it would provide you a not to exceed value!

[Blowby]

Good idea. The mains are 7/16, rods 5/16, fine thread castle nuts. Now if I could just find two torque charts that matched! Anyway according to most charts we're in the ballpark. Interesting the large difference between lubed and dry threads, 20lbs. for the mains according this one.

[JSeery]

I always found that iteresting also. Lubed threads should be fairly consistant, but I would think the various conditions of dry threads would be all over the place in actual clamping force.
