Oil hose and Throttle cable that connect to engine - help with removal - 1995 xp-pics

[shattered00]

Hello all,

I am almost done with removing a 717 engine for a rebuild. I have all screws/bolts removed. I have run into a bit of a snag. I siphoned out the fuel (likely damaged whatever was preventing the hose from going into the tank bc I thought it was just getting stuck on a lip so I tried to force the siphon hose but I realize that it was probably a filter or grate of some sort blocking it and switched to removing the fuel tube from the tank and putting the hose in there). I will maybe buy a "snake" camera to see if there is any damage. I tried to siphon out the oil, but only got a small bit and I was not sure how to remove the oil tank without making a massive mess.

There remains but two things that are still connected to the engine preventing me from lifting it out. One is an oil hose that goes under the engine on the carb side. I cannot figure out how to disconnect it since I can't even see how it is connected. The other is the throttle cable. Below are pictures of what I am trying to convey. Any suggestions on how to remove either of these from the engine? The throttle cable attachment looks similar to the 787 where oil poured out when I removed it... Thank you for any assistance as usual.

For the oil line you will have to remove it at the tank or pull the oil tank too. On a new rebuild I like to drain the oil system and rinse it out then refill with known correct oil.

The cable you are pointing at looks like the oil pump cable. It is easiest to remove it from where it connects to the carbs. Then pull it with the engine.

Clamp off the oil tank line with a small pair of vice grips. Hand held mirrors are of a big help with theses jobs. Or use two vice grips to clamp line and cut it between them. Then replace line with new. Make sure to measure and record length. If it is a two piece tank do a pressure check on it. Seal it up if it leaks down, before you reinstall it.

Thanks for the posts. After a disaster that my friend calls the "BP oil spill," I was able to get the engine out tonight. I clamped all of the lines EXCEPT the one that runs to the engine on the port side. When I removed the exhaust manifold and then the line to that side of the engine, oil gushed out. Unfortunately I was not ready for it as you can see from the picture.

I also had tried to siphon oil out before removing the tank altogether and somehow lost the dipstick tube and the part labeled "b" in the oil tank. Any advice on removing the oil tank since I now for sure have to get the parts out of it? It does not have any oil in it anymore as I unscrewed one of the oil lines on the bottom of the tank and funneled it into a container. I will wash it afterwards per mikidymac's advice and also replace the oil lines per mickirig1s advice. Does the engine appear that it will be a good core for a rebuild? I am going to be searching the forums later to determine what method is best to clean the hull. At this point, with the mess that I have made, I will be gutting it completely and cleaning everything up. I plan to buy a Harbor Freight bead blaster cabinet and repaint the other parts. Thanks as always for the help!

It looks fine but someone has been working on it. The starter is aftermarket and the PTO should be white not black. The factory one could have been stripped and replaced.

Make sure you remove and rebuild the carbs.
SuperClean and Purple Power work magic on the hulls.

Thank you. The carbs have been rebuilt by a friend. I didn't get new needles and seats though...

I got the Purple Power and will go to town on the hull after Xmas. I was further disassembling the engine and got the oil pump off. It appears to have significant rust to the point where one of the metal holes where the throttle cable goes through has a chunk missing (unless it is supposed to have a gap). Should I buy a new oil pump or try to bead blast the rust off and repaint it?

Also, did I disassemble the engine too far for a rebuild? I removed what I think is the rotary valve and didn't realize that I will have to re-time it once the engine has been rebuilt.

Have happy holidays everyone!

That arm looks pretty corroded but nothing is missing.

With the rotary valve off you will have to re-time it. I just print out the degree wheel from the factory service manual.
