I have been working on a 1365 restoration and had to do considerable work to one of the front wheel planetary drives.  The seals were gone as well as most of the bearings.  The service manual calls for Universal Hydralic oil but noticed yesterday when servicing my 1755 that 80 weight is recommended for the front wheels on that unit.  My question is would 80 weight be appropriate for the 1365 or is it too heavy to get into the front bushing.
Along the lines of lubrication, I have always had problems with the 1755 and occasional hydraulic noise.  Some previous posts mention using the correct type 55 oil in the 55 series tractors but never gave it much thought.  Yesterday, I changed filters and put in type 55 compatable synthetic in the hyraulic unit and all noise problems went away.  Just an FYI and, yes, a contradiction to my first question....Dave
