Broken breaker

[gwunsch]

I suppose I should use a 3/4" breaker next time I'll have to pick one up. I over used this one on stubborn crank pulley bolt. I bought it used as well so who knows what was done to it previously. proto 5468. Any affordable recomendations on Breaker bars?

Proto might make a repair kit.

I recently got a US made Craftsman 3/4" bull bar for $31. It will move a stubborn axle but with the help of a 4 ft pipe.

Do you have a local proto dealer? If not call the customer service number listed on Proro's website for warranty assistance.

I have a spare 3/4 cman breaker bar if you are interested

Sounds like a possibility. I'll pm you. Didn't even think about contacting Proto, may have to talk to someone over there as well.

Thanks

If not Proto, any generic rebuild kit will fit.

I did a Honda auto crank bolt recently. I knew my 1/2" pneumatic impact was not strong enough and did not feel my 1/2" breaker bars were strong enough - got a Harbor Freight 3/4" breaker bar (very stiff) and an 8 foot 1" schedule 40 pipe and popped it loose. All of this was not overkill for the task as these crank bolts are notoriously tight! First try split a 19mm deep impact socket, success in second try with a harder chromed socket.

Check your manufacturer's crank bolt prep for re-install.

I have yet to find anything that can stress my 1/2" SK breaker. Granted, I've never had to deal with a Honda crank bolt. Funny how none of my domestic balancers go flying off despite not having 10,000 ftlbs of torque holding them on.

It is usually the first time that is really difficult because of corrosion and other factors. Once the bolt is loose, the crank pulley is easy to remove because it is loose fit onto the crankshaft. Not sure if this is true for all GM, but those that I have seen, the crank pulley is press fit thighly on the crankshaft. So once the crank bolt is removed, a special tool is required to remove the crank pulley.

Um, you guys do know that crank bolts are often put in with loc-tite, and a little heat will change the game right away?

Revs are lower on domestics - harmonic frequencies are transferred to the balancer via interface, so the high rev motors have more vibrations and they need to sink those into the balancer. You should see how hard BMW crankbolts are to loosen. They later started using 4 or 5 bolts vs 1 bolt on the crank snout.

Im viewing this on my phone so maybe the picture is deceiving, but it looks like it only broke the tip, on the 2 breaker bars Ive broke it sheered completely flush with joint.

The break was right at the point where the ball and spring are located in the lug. I would not have expected the break to be there.

There was no lock tite on this one, it was out about a year ago and reinstalled without. it is torqued to 304ft/lbs though.

I was looking into rebuilding, not exactly clear on disassembly, but it looks to have a chrome cover on both sides that are flush with the haed of the bar. Anyone have experience with rebuilding hese bars?

I suspect that it's also due to the V8s having a lot less nasty harmonics than the inline 4s. I will say that the damper on my LS was a lot harder to get off than the SBC and SBF stuff I've experienced.
