Here's my dirtiest chapter in the German van manual
The few times I have had the rear hub apart or replaced rear brakes/cylinders, I could never remember how those springs went back on, so my dirty fingers had to keep picking the book up.. I believe I also looked at it for torque values of the axle nut. LOL, like I had anything to measure 350 ft/lbs.
What's your dirtiest page?
Edit, I just flipped through a few more manuals to find....
^^ Water pump in the long British car manual
^^ More drum brake pages in the little British car manual.
Manuals not shown:
- Mrs McMike's appliance (hardly any fingerprints)
- Harley Davidson factory manual (not yet)
- Previously owned cars manuals didn't have many.
