Overhaul of the crankcase halves

Carefully examine the engine crankcase halves.
Check that the surfaces of the crankcases are perfectly flat using a reference surface. Check that the bearings (4) and (23) are in
good condition. Note that main bearings must always be changed in pairs (refer to the procedure below in "Main bearings").
Notes
When overhauling an engine it is good practice to renew all the crankcase bearings.
Renew the bearings (10) and (15) on the ends of the gearbox output shaft and the timing belt driveshaft bearings (7) and (21).
After having renewed the gearbox shaft bearings (14) and (12), secure them in the crankcase with the spacers (17) and the
retaining plate (9) fixed respectively with screws (18) and (8).
At each overhaul it is recommended to renew also the oil seal (13) located between the bearing (12) and the chain-side
crankcase half: lubricate the oil seal (13) with denatured alcohol and install it in the crankcase half, orienting it as shown.
At each overhaul it is recommended to renew also the oil seal (11) located outside the bearing (10) and the oil seal (20) outside
of the bearing (21).
