Prior to installation, place bearings 1nto an oil container
and heat the oil to 100°C 1210° Fl.
This will expand bearings and ease installation. Install
bearings with groove as per exploded view.
Bearings are pressed on crankshaft until they rest against
rad1us. This radius maintains the gap needed for bearing
lubrication.
