Hi all, was checking the torque of the front subframe bolts on the CR and noticed that it had the updated 19mm bolts (instead of 17mm bolts).

Was curious if the torque spec was still 43 ft-lbs or not... I have a feeling the rest of the bolts may be the same as the original 17mm bolts except for the head. They didn't seem to be torqued to 85 ft-lbs like the rest of the 19mm bolts.
Majestic Honda shows BOLT, FLANGE (12X202) which I'm guessing means it should have the same 43 ft-lb torque spec.

Thanks in advance..

 

the bolts are still the same, only the heads were changed to make them uniformed. So the torque spec would be the same.

 

19mm bolts? thats 4 unga-dungas

 

These charts may help you.

"Nominal diameter" is the diameter of the bolt (threaded portion), not the hex head.








Bolt (thread diameter) versus bolt head (hex head) sizes.

 

I found it strange that Honda was using a combination of M12 and M14 bolts for this application.

Its going to be more confusing now, if they are using 19mm hex heads for both thread sizes.

 

That clears things up, thanks.

Sorry dad

So it looks like they switched from JIS to DIN?

Yep. Hopefully this thread clears things up for anyone in the future.
