Cam bolt removal??

[Hennepinboy]

Looking for some hint on removing the bolt the holds the cam sprocket to the cam shaft. Not sure if is right or left hand threads, I have tried both ways with no success. Using an allen insert in a ½” drive holder, so far I have tried removing it with an 18” breaker bar and using my Ingersall Rand ½” drive impact driver.

I am beginning to think the metal in the oil is from the cam, with all the hardware for the LH lifters in place I get a very loud click when I turn the engine over by hand, the RH side does not make the same noise. I have removed the rocker arms and the noise went away. The side play of the rockers was less then .003 so I do not think that the noise was coming from there. The metal flakes I found in the oil where all ferrous no sign of it being rod bearing material. I had my wife listen when I turned the engine over with the starter and she could hear no noise coming from the crank case.

They're ordinary right-hand threads. Make sure you've got a quality hex bit socket with a good snug fit in the bolt, and go for it. It gets tightened up to something like 60 N*m, so it's gonna take quite a bit of torque to break it loose.

Have some one help you to steady the bike. Use the biggest breaker you can get. Make sure you have the fitting deap into the bolt head and squared up. Use a bolt if you don't have the fly wheel locking pin.. (I used a long drill bit.. When it breakes loose you will almost hear it pop.. They were put on by a gorilla a the BMW plant!!

Ditto what Wild Bill said.

 

I had the same problems removing said bolt. I fought it so long that in the end I'd chewed up the head and needed to use a new bolt.

 

We heated the bolt (carefully!!), and I torqued away with a 18" breaker bar that had a 36" pipe on the end of it, while my partner gave it a good hit with a hammer. Finally it gave up
