My elderly neighbor has a Case DX55 that is long overdue on pretty much all maintenance. I plan on getting it all up to date to help him out. I bought a service manual on ebay (digital copy) and I can't seem to find a maintenance section. It seems to have everything imaginable in it but that. I have never touched a Case before so I would like to know the proper procedure for draining/filling the hydraulic/transmission system, changing the front axle oil, where all of the grease fittings are located, ect. If anyone knows where I can find the proper literature for maintenance on this tractor it would be greatly appreciated. Thank you!
