I am trying to get this bolt out and it’s sunk into the washer and my air gun keeps jumping off of it. Any tricks or suggestions how to get it off would be greatly appreciated - also is this bolt standard threaded or reverse threaded?

I don't know about the thread direction. I'm gonna say it's standard. You might try an air chisel to get it broke loose.

I don't know about direction but maybe if you grind away at the end of the socket the get rid of any rounding over in the socket right where it grabs the bolt.

Square up the socket so it grabs as much of the bolt as possible. I've done this by holding the end of the socket on the side of a grind stone on a bench grinder.

If you are using an impact socket, try a 6 point chrome socket, they have less of a bevel and make more contact with the bolt head generally. Most of the time left hand thread bolts have an L on the head, also this bolt may have some type of thread locker on it, heating it up some helps to break thread locker loose.

If all else fails, weld a nut the same size to the bolt, welding inside the hole. Then you'd be able to get a good fit to a socket to remove it.

If all else fails, grab the head in a vise and turn the shaft. grab it with vise grips or a pipe wrench on a section of the shaft that doesn't come in contact to a seal or bearing. And like stated already heat would be good too.

 

Good luck

Yes... . what he said.    I've got a couple sockets that have had material removed from the end to eliminate the taper on the inside. It will allow the socket to put more of the flats against the  bolt head,  Do it to a six point socket.    Rick.

I have rebuilt the bevel gears several times.  Never had a problem with that bolt, so I suspect a standard thread.

 

Does anyone know of a manual detailing how to rebuild?  I know there are shims available to set the gears, but no idea how to set this adjustment.

I too am interested in Bob Mason’s request for a manual detailing a bgb rebuild. I have mine pulled apart, out of a Simplicity 725, and ought re-assemble it as properly as I can - new seals and shims. I have followed another thread, with interest, identifying the seals.

Well Scott, how did this all end?  Did the bolt come out?
