Refitting the crankshaft bearings
- This operation requires assembly by temperature
- Dip the bearings in oil bath when this is still cold.
Avoid contact between bearings and container.
- Use an appropriate amount of oil (approx.1 l)
- Gradually heat the container with a thermal gun
until the oil temperature reaches approx. 150°.
- Check the temperature using a multimeter provi-
ded with thermal probe
N.B.
IF THE BEARINGS WERE IMMERSED INTO HOT OIL, THEY
WOULD BE IMMEDIATELY DAMAGED.
- Place the crankshaft on the special support
- Alternately introduce the 2 bearings to insert
them home.
- If required, use a specific pipe to ensure their in-
sertion.
N.B.
THIS OPERATION SHOULD BE PERFORMED QUICKLY
AND WITH PRECISE MOVES. OTHERWISE, START OVER.
