Some Lincoln Continental 7.5L Engines
Some .010 undersize crankshafts were used in production on 7.5L (460 CID) Engines Lincoln Continental engines including the Mark III. These engines can be identified by the letter M and/or P (indicating main or crankpin journal) stamped on the right front of the cylinder block near the engine date code stamp. The back of the bearings in the engines involved are stamped .010 U.S.
The AERA Technical Committee | | ENGINE OIL RECOMMENDATIONS FOR FORD VEHICLES | Engine Oil Recommendations For
Ford Vehicle Applications & Engines
The AERA Technical Committee offers the following information supplied by Ford Motor Company on recommended engine oil for Ford engines. Previously AERA published Technical Bulletin TB 1738, the information in this bulletin is an update to that bulletin. This latest information should be highly considered as quality improvements have been made to most engine oils. The current engine oil used by Ford during the vehicle manufacturing process is SAE 5W-20 Motorcraft oil. This oil may also be used for older vehicles described in chart 1 below.
The engine oil recommended for use in 2001 vehicles is SAE 5W-20 motor oil. This oil has an improved formulation to improve fuel economy. This oil can also be used to service some previous model year vehicles.
Use SAE 5W-20 engine oil at recommended oil change intervals for 2001 vehicles, with the exception of the following vehicles listed in the Exception 2001 Vehicles chart.
All 2001 vehicles other than those listed in the Exception 2001 Vehicles chart are being filled with SAE 5W-20 motor oil at the factory and should also be serviced with SAE 5W-20 oil.

The AERA Technical Committee | | NEW GOVERNOR KIT AND SHIM | New Governor Kit And Shim
The AERA Technical Committee has been informed of a new governor kit and shim for some Continental and Perkins engines. The manufacturer part number is 529737M91, which is available for the following gasoline engine models:
Continental
Z129 - Right hand thread
Z134 - Right hand thread
Z145 - Right hand thread
Perkins
AG3-152 - Left hand thread
The shim thickness should be .020.
The inside diameter should be 2.250.
The outside diameter should be 4.062.
Installation: (Figure A)
1. Continental: Use shim and nut as shown.
2. Perkins: Disregard shim and nut.
3. Pilot diameter on nut must be inside bore
of ball retainer.
Throttle Rod Adjustment Instructions: (Figure B)
1. With throttle rod assembly (1) disconnected at governor throttle lever (2), advance manual throttle control lever on tractor to full open position, to place maximum spring tension on governor.
2. With carburetor lever (3) just at wide open position (but not under tension), adjust clevis (4) so that it just falls into terminal hole on governor throttle lever (2). 3. For Continental engines, turn clevis (4) one full turn to lengthen rod assembly (1), for Perkins engine, turn clevis (4) one full turn to shorten rod assembly (1). 4. Reconnect throttle rod assembly (1) to governor throttle lever (2).
The AERA Technical Committee | | REVISED PISTON PIN BUSHING CONTINENTAL TM&TMD | Revised Piston Pin Bushing For
Continental 2.0 & 2.7L TM & TMD Engines
The AERA Technical Committee offers the following information concerning a revised piston pin bushing for Continental 2.0 & 2.7L TM & TMD engines. The previous design was a split seam solid bronze type bushing. The current design is a solid bronze type bushing with a steel backing.
Beginning with engine serial number 94041355 the steel back bushing is used. This revised bushing is thicker and has a slightly larger outside diameter than the older style bushing. The original connecting rod requires machining to a larger small end bushing housing bore diameter to allow use of the new bushing, Part # TM27G00305. The finished inside diameter of the revised bushing remains at 1.1255-1.1259 (28.588-28.598) has not been changed.
To convert the non-current rod pin end housing bore, simply increase the diameter from 1.1870-1.1880 (30.150-30.175 mm) to 1.2049-1.2059 (30.605-30.630mm).
A revised connecting rod assembly is available with Part # TMD27D03002, it has the pin bushing installed and sized. As a note, Continental is no longer supplying the older style bushing and AERA is unaware of an aftermarket supplier.
