Had this for around 6 years and finally getting around to checking it out. Bought it from the original owner. He never mounted the bucking spike.

Nice! Looks to be in good shape.One thing to keep an eye on is the muffler loosening up on you.I bought two 450's back in Jan.,one has no spark & had a broken muffler half rattling around in the muffler shield,the other had what I thought was a good muffler on it til I took it off & found that it too had been cracked or broken,but was brazed back together.Plus,one of the saws had a stripped out mounting hole for the mounting screw.I don't know if there was an inherent problem with the mufflers on this model.If you need to get a new muffler (if you can even get one) be prepared to pay dearly.There's only one on feebay & it's USED & they want $65 + shipping.

450’s rock. I can’t imagine that saw needing much.

Yes, 450/550 mufflers did have issues. Common issue is the top breaking off from the bottom. There’s a new one on fleabay and the want 116 bucks for it! 😲😲😲

How did you find out it was leaking?

I filled up the fuel tank and left the oil tank empty. The next morning, the levels were equal in both sides with fuel. I think their fault in design is the bottom of the aluminum partition is only supported on one side and not sandwiched between the castings.

Looks like an oversight with the lack of at least a cast bridge across the mid section of the fuel tank. Seems a lot to ask of the aluminum part. Got any ideas as how to stiffen the aluminum oil tank half?

They would have to leave the fuel side open so a line with a filter on it could flop around and get all the fuel, no matter which way was up.
There would not be much pressure on that tank so I doubt it would be a huge problem. Glue the divider back in to the oil tank side, then attach the gas side. I am thinking it will last another 40 - 50 years.
An attempt to curve the aluminum so it put some pressure on the oil tank side of the joint when the tank was screwed back together but that could lead to more trouble. It may not have been leaking there anyway, the joint is pretty long and could leak anywhere.

I've noticed that my 550 has more screws in the tank assembly than my 450. Don't know if its because the 550 is newer and updated or just built stronger. I know the handle mount area is different between the two. 550 is for a round bar and the 450 is made to fit a flattened bar. Maybe someone has the answer.

This should be the answer you are looking for.

I found an old Homelite dealer a few years back with a NOS tank--------------------------------------------------------------for $200. 😕

Glue the divider back in to the oil tank side, then attach the gas side. I am thinking it will last another 40 - 50 years. Rereading this has made me think that all three pieces would need to be glued at once. If my suggestion was followed the divider might bulge out, not fit flush with the oil side, that would compromise the whole joint. And with the formed area of the divider, it would be very stiff in the area where it is unsupported by the gas side. I think cleaning it carefully, making sure that the parts are as flat as possible, and gluing it all together at once is the way to go. That way the final fit can move any excess glue to allow the parts to relax before the glue sets, preventing bulges that could possibly break parts or cause leaks. I would use slow setting glue. Maybe that is covered in one of the manuals.

I'm mostly with Dan on this, having failed after 40 some years, reglued well it should be good to go again for a while. What kind of adhesive were you planning to use? I would be going for something that stays relatively soft & flexible.
My first inclination is to try to glue it in two or even three stages, the divider to the oil tank side first. Then you can know it's flat and secure after the adhesive set, before closing it up with the gas tank side. Just presents a challenge in clamping it while the adhesive sets. I think I'd take the divider as you have it in that last picture and cut a good flat board to allow the deformation to sit down inside it, inside of divider facing up, leaving the entire rim backed up by the board. Maybe a couple pins/dowels through the holes to keep everything aligned and glue the oil tank half down over it, using some kind of weight or straps for clamping pressure. After that, you could even glue a reinforcing rib to that area that isn't backed up inside the gas tank, before closing it up with the gas tank.

Well, after sitting with the fuel side of the tank full for 4 days, no leak. The view inside the oil side looks good to go.
