After a very exhaustive and time consuming search, believe that I've finally managed to determine what parts of the OEM Massey Ferguson manual cover the Continental Z-134 and Z-145 4 cylinder gasoline engines. At this time, available information seems to indicate the following.
The OEM Massey Ferguson manual was originally a 5 (or more) volume dealer set, that was divided into groups, sections, and parts. Groups were the major categories such as engines, sections were the secondary categories such as engine models, and parts were secondary category chapters such as engine specifications. Division nomenclature would typically be displayed at the top of each page as "GROUP XX - SECTION XX - PART XX", with XX being whatever letter or number was applicable to that group, section, or part. The group and section covering the Continental Z-134 and Z-145 4 cylinder gasoline engines were as follows.
Continental Z-134 4 Cylinder Gasoline Engine:
Group I - Engines and Engine Systems
Section B - Model Z-134 Engine
Continental Z-145 4 Cylinder Gasoline Engine:
Group O - Basic Engines and Procedures
Section O - Model Z-145 Engine
The parts covering the Continental Z-134 and Z-145 4 cylinder gasoline engines were as follows. Note that parts 1-2 do not include specifications for the oil pump, which are required if performing an engine overhaul.
Part 1 - Specifications
Part 2 - Engine Overhaul Procedure
Part 3 - Fuel and Air System Servicing
Part 4 - Lubrication System Servicing
Part 5 - Cooling System Servicing
Part 6 - Electrical System Servicing
Part 7 - Special Tools
Many reproduction Massey Ferguson manuals seem to have been assembled from various parts of the original OEM Massey Ferguson multi-volume dealer set, and many reproduction service manuals for the Massey 135 tractor seem to have parts 1-2, but are lacking parts 3-7. Please keep in mind that much of the information I have found is extremely limited, so the accuracy of some things is still questionable. Use at your own risk.
As mentioned previously, I do have a few leads for obtaining more concrete information, but would rather not say much more until I know for sure.
