Hi Everyone, I have a 763H and I am attempting to change the engine oil. It supposed to have a hose with a plug on the end coming out of the right side of the engine compartment. I cannot for the life of me find it. I've been in there with a flashlight and looked from every direction and I don't see it. The only thing I can think of is one of two things. One -- it doesn't have a hose on the plug or two the hose got tucked way in the back somewhere where it can't be seen. If its the latter, can I see the back side of the engine if I tip the cab open? I've not done work on the machine before. Thanks!
