2.1.2 Crank Mechanism Assembly
After cleaning the crankcase, reassemble the crankcase mechanism as follows:
A) Thoroughly fit the plunger guide seals into their seat on the crankcase as shown in fig. 5a,
using the appropriate tool (p/n F27904900).
B) Introduce the pre-assembled plunger guide/connecting rod units into their seats; to facilitate
tightening of the connecting rod cap, we advise to position the connecting rod so you can
easily read the number. To easily insert the crankshaft, without the key, fully push in the
plunger guide/connecting rod unit, as indicated in paragraph 2.1.1, Section B, as shown in
fig. 4.
C) Before assembly of the side covers, check the seal lips for wear. If replacement is necessary,
position the new ring using the appropriate tool (p/n F27904800) as shown in fig. 5.
If the shaft presents diameter wear corresponding to the sealing lip, to avoid the need for
grinding it’s possible to position the ring as indicated in fig. 5.
