harmonic balancer bolt

[BOB GRAGG]

Help i am in the process of changine crank sensor,timing belt,water pump. I have tried all methods of removing crank bolt,impact wrench,even the wrench on the frame bit by using the starter.Can't get it to brake loose any ideas would help

The bump-start method didn't work? Get a bigger, better wrech/rachet/socket. Something has to break.

I got a good 19mm impact socket with a breck over bar, do i let it rest on the frame or raise it a bit and let it slam the frame.

 

[yamahaSHO]

I always let it rest on the front (generally with a block of wood on it).

You put a block of wood on the frame and raise the breaker bar handle a few inches above it. Then it will develop some momentum before it whacks the frame.

That's how I've done it....never seen bump-start not work but I'm sure it's totally possible. Otherwise you can cut the collar off the bolt head with a hole saw or otherwise sharp power tool....but then u gotta find a new bolt, which isn't fun, but it solves the immediate issue.

thanks to all for the response, i tried this method several times, the car only has 88k could the starter be to weak to do this

 

[silver93sho]

Wouldn't think so If it has been starting the car without issue recently....

keep using the starter bump over and over again.

Exactly what happened with my SHO, the starter method FAILED. I did it over and over, swapped batteries and still failed. I tried 4 different impacts, all failing. I ended up drilling into the ****** all around, then it broke loose with an impact.

This is exactly I tried and this is what I had to do.

Used a corded drill with a hole saw on the ******. Once the ****** was off, I could unscrew it with my fingers.

Usually the socket

If it is still drivable, you can take it to a heavy equipment shop that does truck tires and such. They'll have an impact gun and compressor that can pop it loose. If you have an air chisel, you could try putting a blunt end in it and use it to vibrate the head of the bolt real well. Then try the starter bump again.

harbor freight has cheap hi-po impacts.

That's a good point too...if they cant pull it off with 3/4 impact then nothing will!

harbor freight electric impact wrenches are junk! Do not buy

 

[BOB GRAGG]

Got it to pop loose dont no if it helped but sprayed pb blaster let it set 5 min, got a better socket and breakover bar . I think the answer was better tools.

same thing happened to my 92 w/ 136k
i ended up waiting until i found a replacement bolt off ebay (the only one) and drilled the bolt out
this is one part that isn't easy to get from a junk yard
