I don't believe the motor mounts need to be disassembled but lifting the
motor somewhat I believe is needed.

As Roland pointed out, the connection to the oil cooler is very very
difficult to loosen without damaging the cooler. Some owners have simply
replaced the OEM lines with hydraulic grade hose, cut off the old lines
at their press fittings and used hose clamps to attach the new hoses to
the cooler's steel pipes.

Be creative, there's nothing sacred about these cooler lines, new
hydraulic quality hoses will also do the job - and YOU get to route them!
