Thanks for the picture. The previous owner must have made some "modifications" to the oil lines and the engine tins. When I installed the oil lines, they were too short to go over the fire wall to the oil filter so I took them to NAPA and had longer hoses made. I got home and put the lines back on and they are now long enough but now I discovered one of the bent tubes that comes out of the engine is not right and the side panel will not go on. The one tube sticks out about 1" farther that the other one. I filled the engine with oil before I tried to put the side panels on

so I hate to drain it just to fix the oil line. I am thinking about just using it without the side panels for now until it is time to change the oil again and fix the tube then.
Is it going to hurt the tractor/engine to run it without the side panels on?
One other question, what should I use to clean the terminals on the back of the PTO switch, ignition switch etc.?
