[ONEDOTCOM]

Ive been reading on here for sometime now and have decided my seal is out(hydrolic pump). hydrolic fluid in crankcase, blows dipstick...bla bla. Read where that 9 times out of 10 the pump is gonna be bad . change the seal and its the pump lose all fluids and seal again. Ive found a pump for 450$. NOW i dont clam to be a mechanic. I have several tools...a 300(or so)piece craftsman tool chest.. bla bla. CAN i do this myself or no take it somewhere? do i need any special tool or knowledge to do this. A good shade tree and several boxes to put parts in! encouragement me.. Thanks
