getting CB H beams apart

[Jonny Grigg]

These days I am not embarrassed about asking dumb questions.... maybe I should be 

Anyway, it has been a while since I have built an engine, and the last one I did I don't remember my H beams being such a bitch to get apart. These are fresh out of the box and the 5/16" bolts were done up really tight- once I shifted them I cannot get the bottom cap off. Any hints and tricks? i don't want to brutalise them.

thanks

i unscrew the bolts a bit and tap them slightly with a hammer with a small amount per time...

That's exactly how I get mine apart.

Thanks guys, I was just a bit conerned about doing that in case it damages the threads.

You only back off the bolts 2 or 3 threads and tap the bolts enough to break the cap loose. Any more and you could possibly damage the threads in the cap or the bolts. You won't need a 5lb sledge hammer, a small dead blow or small ball peen hammer is plenty to do the job without damage.

I use a small nylon hammer after backing bolts off 4 threads

Take the bolts back out and restart the motor WFO.

I use a detorqueing tool.

Just rev your engine above 6000 rpm
