thought i`d throw this in the mix. my stepson was working on a compact car and was having no luck getting the bolt out of the harmonic balancer` he had tried everything in his arsenal nothing worked` 3/4" head I finaly got it out with right at 500 ft lbs torque. never ran into a bolt that small that tight
Sometimes the iron throws a challenge at you. Did a set of turbos not long ago and the one nut I could barely get a half-moon wrench on needed heat AND a snipe to get it off. Figured the nut would either come off, the stud would thread out or I'd just snap it off. Ended up the stud threaded out.
On the old V8's or 6's I used a breaker bar and tapped the starter.
Honda v6 are known for this. Broke my 1/2 inch bars. Succeeded with 3/4. Some say high power 1/2 impact with a weighted socket works well. I’ll find out in a few months.
Weighted socket is the answer. Especially Honda crank bolts. Some sort of un-natural phenomena creates a torque that resists even a Milwaukee 3/4” 18v Fuel. It’s an amazing lesson in physics when you experience the black magic of a weighted socket. Check out the Torque Test Channel, if you haven’t done so.
I’ll look forward to it. Video seems to prove it out.
Do they make weighted hex sockets? Deal alot with 16 mm socket head bolts and its common that my 3/4" air impact at 1,800 ft-lbs won't bust them free unless I put heat to them.
Not seeing them. I suspect additional weight could be added to this with some machine shop work https://bti-tool.com/metric-hex-bit-socket-3-4in.dr.-x-16mm-hex/
OMG, yeah. Those metric socket head hyd cyl. Head bolts get 6’ long cheater pipe tight, too.
I'm going to be on my 4th 3/4 drive 14mm impact hex key socket of 2022 very soon.
I used the starter and a long breaker bar when I did my wife's honda v6. They are tight, and there's not a lot of room for big tools in there. Its the procedure they actually give in the manual.
I think there are several things we are a long ways from truly understanding . This stuff is very interesting.
it was the one shown in the first part of the video. with the crank holding socket
I think my local orielly's has the socket/wrench for the honda's in its loaner tools.
the weighted socket works just like a bigger hammer not bouncing where a small one would. it helps put the power down where its needed.
