Last fall I developed a serious leak out of the relief valve plug on the hydraulic pump of my 1958 445 Moline. I expected a broken valve spring or something in the valve seat so I pulled the plug and got a heavy flow of fluid so I replaced it. Now that it's warmed up, I'm tempted to remove the pump and disassemble it but I don't want to cause my self a bigger problem.
So can anyone tell me if I can unbolt the pump and remove it without a problem? How much of the hydraulic fluid do I need to drain to prevent a spill? Is it unwise for a shade tree mechanic to disassemble the pump? There's really no one in my area that services these old workhorses. Any advice would be appreciated.
