Just completed my 400 hr service on L4701.I’ve been pretty impressed with accessibility when servicing machine engineers did nice job.In some heavy equipment excavators,dozers and FEL I’ve seen some real pain in the ass to service machine.My question is when I pulled owners manual out to make sure of service being needed and how to preform the service.At 1k there an oil Separator fiter has anyone did there’s yet I’m 6OO hrs away but like to be prepared.
