216 Chev Engine specs

[Euan McDonald]

Looking for the main & bigend bolt tightning torque for the 216ci, had a quick look in MB-C1 with no luck.

Euan,

I have TM10-1339 for a Chev 1.5 ton 4.2 model 4403 with a 216.5ci, assume the US made one is the same?

Figures are;
Mains ( with threads oiled ) 100 - 110 ft/lbs
Bigends ( with threads oiled ) 40 - 45 ft/lbs

Euan:

In MB-C2, there are the following specs...

Cylinder Head Bolts...75-80 ft lbs
Main Bearing Bolts.....100-110 ft lbs (with oiled threads
Valve Rocker Shaft Support Bolts & Nuts...25-30 ft lbs
Conn Rod Bolt Nuts...40-45 ft lbs ( with oiled threads)
FDlywheel Bolts...35-50 ft lbs

Does this help?

I say that because many of the later postwar Chevy books list only the torque for the post war engines which kept changing generally increasing significantly. My point in mentioning this is that if you are assembling an original engine 1940-1945 those are the torque values you want to use. If you are working with a post war 216 figure out the year from the casting numbers and use the appropriate torque values. If you are working on a 235 or 261 be careful to use the correct vintage information.

Also working on the crank bearings particularly the babbited type be sure to follow the shimming instructions. If you want to hear what it sounds like when you goof on fitting the rod shims listen to my engine `52 216 engine running on test stand http://canadianmilitarypattern.com/EngineTesting.htm with two rods with .002 to .004 more clearance then called for.

Thanks Jon & Phil, all info now passed onto fellow club member doing his rebuild over Xmas in time for Corowa (year of the Karmen).

I was wondering why you were playing with a 216, as I know what you think of them. Thought you might have had a moment of weakness and were going to put the gun tractor back to original!!!! :idea:

[Euan McDonald]

Hi Rob,
Well funny you should mention the engine in the GT, I was thinking of fitting a 235 to the GT & swapping the 292 into the C60X to make a new recovery truck. Are you planning a run down to Corowa?

[Robert Farmer]

Yeah Euan, I should be there but I don't know what I'll be driving. May be a slacker and go modern!
