2 weeks ago i started it up for the first time in around 8 months, and after few mins it started overheating so shut it down and had to add about 3 gallons of antifreeze. used it for couple of hours after that and all seemed fine and antifreeze was still full and oil level still perfect. now for the past few days ive been clearing a spot for a hay barn, yesterday when shut it off all seemed fine. went to start it today and the engine ran away when i cranked it, turning the fuel lever off did nothing, so i pulled the air intake and smothered it off with my shirt. and noticed the air filter cap had come loose, that lead to me cleaning the filter out, which lead to me having to take the breather cap off the top of the valve cover and when i did i found a oil/water sludge on the cap and the mesh breather. the oil still checks perfect level and nothing but black oil on it when i checked it before cranking it today and right after getting it shut off. and the radiator is still full and clean. the antifreeze had to went somewhere the first time but not sure where, it looks like clear water dripping off the breather mesh cat 941 with a engine from a 951b d330c if i remember correctly. anyone have any ideas what my trouble maybe and where to start looking?
parked my 941 yesterday for 3or so hours and it ran fine and turned off fine, cranked it this morning and soon as it cranked it ran away and i had to pop the intake cover off and smoother it. all of the linkage is moving but i feel like the lever is not pushing forward into the off position as much as it has been. maybe something inside the governor has broke?
Your water pump gland seal has failed i would think.
very well could have, ive read several people having that problem, i have got to figure out the runaway problem before i can figure that part out, im thinking the rack is stuck but i dont know what to take off to get to it to try and free it up.
