Engine #11 - Main Shaft Rollerbearing

Life's a bitch...   Thank God there's Harleys...

Here's a few pictures that T made during re-assembly of the rollers into the main shaft bearing of our 1973 Harley Ironhead Sportster engine.

After we took this picture, we installed the main shaft roller bearing washer that keeps the rollers in place to ensure that the smooth ride lasts a bit longer than a few miles...

Here the main shaft roller bearing washer has been slid into place over the rollers, and is now covered by the main shaft roller bearing retaining ring (arrow). We are now ready to install the oil seal.
