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.
Here you see the main shaft sticking out of the back of the transmission housing.
Here's the Harley rollers ready for re-installation into the bearing of the main shaft.
We slid in the rollers one by one.
The rollers just fitted the annulus. 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.
