Oil holes for cam bearings
Ok, I think I will start a new thread instead of taking along on an old one. I want to thank Tom and others for the help with finding the holes in the valve chamber to oil the mains. Now, I can seem to only find one hole that goes to the camshaft. It is in the front of the valve chamber, but are there more, or is the rest of just oiled from splash?? I'll get this engine figured out someday yet. It runs great, but I want it to last a while, so want to make sure it is oiling properly. I won't put any long trips, or many miles per year on it, so if it will last me a couple thousand miles, of short trips around town, It will probably outlast me. I will change oil probably every year, even though it will probably only have one or two hundred miles. It drives fine, and gears and clutch are all good, and has had a lot of new parts put on it shortly before I got it.

Re: Oil holes for cam bearings
The center cam bearing is oiled right away by the oil coming up from the pump. Sometime during 1929 an oil hole was added to help oil the rear cam bearing. Notice my pictures don't have that rear oil hole for the cam, and I won't be drilling it. I think the splash is enough to keep it going another 80 years. The front bearing gets a good flow of oil over the front dam.
BTW, the SERVICE BULLETINS show the hole being added, but I don't recall the month. |

Re: Oil holes for cam bearings
Mine is a 29. Forgot the month right now, but that probably explains why I can't find the holes. Thanks for the info.
