C) Before reassembly of the side covers, check the seal lips for wear. If replacement is necessary, position
the new ring using the correct tool (#F27904500) as shown in fig. 5.
If the shaft presents diameter wear corresponding to the sealing lip, to avoid the need for griding it’s
possible to position the ring as indicated in fig. 5.
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 proper
tool (p/n F27904900).
B) Introduce the pre-assembled plunger guide/connecting rod units into their seat; to facilitate tightening of
the connecting rod cap, we advise to position the connecting rod so you can easily read the number. To
easily introduce the crankshaft, without the key, fully push in the plunger guide/connecting rod unit,
as indicated in section B, paragraph 2.1.1, and shown in fig. 4.
