Topic: CB750K2 oil pan removal

[jeremyillingworth]

I'm in the midst of my 6000 mile tune up and got to pull the oil pan. Does anybody else have trouble with the bolt next to the oil drain plug? It's so close to the pan I can't get a socket on it. Eventually I had to do the unthinkable and use vice grips to break it free and then was able to use a stubby wrench to get it out.

After the bolts were free the #3 muffler prevented it from coming out; I'm guessing it's a bit bent, so I pulled the bolt from the back and made room.

After seeing the stuff hanging from the screen I'm guessing the difficult bolt had been deterring others from dropping the pan for quite a while. The screen didn't seem interested in coming out easily, so I cleaned it in place and noticed a small tear in the screen, so I'm doing this all over again when the new one arrives.

Is this small amount of black particles normal? There were also a couple of bits of aluminum but not many.

I did have trouble with that bolt even with the engine out of the frame. I had to use a thin wall socket on that.

Those black particles are most likely from primary tensioner wheel, and cam tensioner. Would not worry much about those. What do you mean by bits of aluminum? How big?

Now I'm going to have to track down a single 10mm thin wall socket.

The aluminum particles were similar to the medium sized plastic bits. They were quite thin. What do you think they might be?

A 1/4" drive socket may fit on that bolt head or grind down a donor a little.

+1 on the 1/4" drive socket.  Recently swapped out oil pumps, and used a 1/4" craftsman deep socket, no grinding necessary.

I was already using a 1/4" drive socket; I guess Canadian Tire sockets are a bit thick walled.

I had the same issue on my 750 K3. I think it was the same bolt location. Odd thing is, the first time I dropped pan I did it with pipes on and I don't remember having the issue, but the second time I dropped pan I had the pipes removed and that's when I was unable to tighten that one bolt the way I wanted. The MM socket wouldn't grab it and I couldn't get the wrench to it due to hitting the frame or side stand. I didn't try a 1/4". It's not leaking, so it's OK, but it was annoying to say the least.

I also used a mastercraft (Cdn Tire) 1/4" drive deep 10mm on mine. Fit no problem.

When you go to put your pan back on, put that bolt in first and just one-finger tight with your ratchet. There might be just enough side-to-side play that the socket will fit when you put it on first.

That might be why I didn't experience it the first time I dropped the pan now that I think about it. I know that was the last bolt I got to when I dropped the pan the second time and had the same issue.
