Itinerant Air-Cooled

Today while adjusting my brakes after 1000k mile break in I thought I'd grease the beam until clean like Colin was just jabbering about.
Pump pump, a couple times it comes out clean. But wait, it's not quite the same gray as I'm pumping in let's keep going. 20, 30 pumps later I get actual clean. Yes, the same for all zircs. Took me most of a container to get through it.
The front end is much quieter now, very nice. How nice to be doing such an inadequate job for so long.
What a mess this makes, must this be done every 6k miles? Yuck.
thank you,

You are forgiven, my son. Now say three Hail Marys, five Our Fathers, and an Act of Contrition. (And it's been about five years since I've greased the front end, so I'll be right behind you at the confessional.)

Funny, I just did mine while I was under the car replacing the small rubber tube inserts that seat onto the nipple of the master cylinder. I looked over at the zircs, and figured now was a good a time as any. It is a mess.

Does anybody have a guess as to why the early bay and late bay have different lubrication intervals? Dealership cost savings? Some funky engineering when the beam changed around 1970? Different seal design?

I think it was both the automobile industry-wide consensus that new lubricants at the time were now longer-lasting and a competitive push to extend maintenance intervals. We learned as well that cleaner exhaust made the oil last longer, too.

Yes, it was a pain in the ass to bring your car in for a oil change and valve adjustment every 3,000 miles.
