VCCA Home Forums TECHNICAL - GENERAL Mechanical - Engine, Trans, etc pressure plate bolt torque -50-216

what is the torque for the pressure plate to flywheel bolts for a 50 -216 cant seem to find the numbers in my service manual all i could find was tighten evenly to prevent distortion

In that time period there were few if any published torque specs. I suggest that you should consult a table of standard fastener torque values.

The key is to determine if you are dealing with basic Grade 2 hardware or Grade 5. Are there any marks on the heads of the cap screws?

Depending on standard or heavy-duty, you have either 6 or 9 bolts, respectively. Now this here, right here, ain't no rocket science.

Using muscle memory, as to what you think will be enough to get them tight, just go a little short of that feeling. You don't want to wring them off or exceed the bolts elasticity.

Muscle memory torque will be close enough. After all, there are so many of them, that just plain old tight will serve and not something that will keep you up at night worrying about. If you think it will keep you up, just tell the missus that if she will do this simple job for you, you'll take her out for a steak dinner or wash the windows. You know she will do it right and soon.

Hi there stefakicoupe

First you will need to look at the heads of the bolts to determine the grade of bolt you have.
No marks means Grade 2
3 radial marks means Grade 5
6 radial marks means Grade 8

I don't think they will be Grade 8 unless they've been replaced,
and they should be 3/8" course thread by 1" long.

According to published charts, that would mean a torque of:

Grade 2
20 ft/lbs dry or 16 ft/lbs oiled

Grade 5
33 ft/lbs dry or 26 ft/lbs oiled

Personally, I've always torqued somewhere between the dry and oiled spec with the threads oiled with a light oil.
Actually for most things I use Charlie's method.
You just develop a feel for it.
You tighten until it's just tight, and then torque in a little bolt stretch without going past the yield strength (stripping the threads).

Hope this helps. :-)

I often use similar to Charlie but I call it "elbow click" but then I have more than 40 years swinging spanners for a living.

If I remember correctly they have a very shallow heads and an ordinary socket will not do the job. I think I ended up grinding some off the face of my socket to get it to work.

MANUAL SAYS 25-30 FOOT POUNDS/

I was mistaken. I was thinking of he flywheel to crank bolts,
