Tandi's 1949 Willys-Overland
Jeepster:
Lubrication Specifications
From the 1948 Willys-Overland Mechanic's Manual covering
All Willys models:
48, 39, 4-40, 4-41, 4-42, CJ-2A, 463, 2WD, 4WD, and
663
This is a direct transcription of the Lubrication Specifications
chart in my Willys Mechanics Manual. All terms and descriptions are
exactly as they appear in the manual. Note that not all entries apply
to all vehicles and that some vehicles have special instructions not listed
here. I have noted those differences that I am aware of. The
chart and footnotes between the lines are from the manual, the notes afterwards
are added by me.
