Engine #12 - Oil Seal and Sprocket
Life's a bitch... Thank God there's Harleys...
Here's a few pictures that T made during re-assembly of the Harley oil seal and sprocket wheel onto the main shaft of our 1973 Harley Ironhead Sportster engine. LnT purchased a new oil seal and a new gasket for the Harley oil seal housing. Other Harley Davidson Sportster parts were cleaned, polished and re-used as much as possible.
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.
LnT bought a new Harley oilseal and a new gasket for the oilseal housing. On this photograph all parts are ready for installation onto the main shaft of the Sportster tranny.
On this photo the oil seal and gasket are fixed in place, you're looking at the top of the oil seal housing.
After we completed the installation of the oil seal, the sprocket wheel was fixed onto the main shaft. At this stage our new lockwasher for the sprocket wheel had not yet arrived, but for all practical purposes:
Another milestone achieved!
