have 1973 case b backhoe. it ran fine until i changed transmission fluid. replaced hydraulic filter (front of radiator). took hydraulic hose off pump to make sure pump is working. pumps working great.
1-does hydraulic fluid move the tractor? does the hydraulic fluid get pumped to the rear to help propel the tractor?
another thing which might be related is: im getting water in the hydraulic fluid and hydraulic fluid in the radiator. when i removed the hydraulic hose to see if hydraulic pump was working i seen the hose ran to the bottom of the radiator. the hydraulic fluid pumping out of the pump was the same milky color as as the water in the radiator. does the hydraulic/ transmission fluid get cooled via radiator? if so do you think i have a cracked radiator and if so do you think this might also be contributing to the hoe not wanting to move?
any help would be great. i bought one of those manuals cd from ebay and it is junk.
thanks darren
 
You probably need to pull that radiator since you're getting oil into the radiator and a mixture of oil and water in the transmission fluid. Talk to your local radiator shop to see if can be repaired. You may need to purchase a new radiator. Hal
