yeah it looks like a 188 Case Sonny..sorry for confusion I did work on one with a Kubota in it..you can pull the inj pump on this one easy with just removing the radiator and fan..pull off the drive gear cover and right there is the nut to hold the pump into the gear. Im working on the Bobcat skid steer I just bought..a LOT of things wrong with it, glad I dug into it the main hyd high flow hose was burned and ready to fail,that woulda been a fire for sure..many hoses deteriorated from heat, the exhaust manifold and turbo right on top of a lot of them..I have thermal firesleeving ordered to protect the new hoses,.only $15 for 3feet but it protects the hoses from heat..
Bobcat shoulda put it on when new..you have it easy with that old Case, this newer electronic joystick controlled machine is a pleasure to operate but becoming a nightmare to get straightened out..lot of wear
