The crankshaft assembly is shown in figures 21 and 22. A more detailed drawing can
be found on the parts page.
16.1.1 REPLACEMENT OF A CRANK/CRANK BEARING
Replacement of a crankshaft crank is necessary when it is cracked or when the nuts
regularly come loose from the big-end. That is, if the crank bearings, the crank-
bearing fittings, or the big-end pin holes in the crank are damaged. Replace the
crank/the bearing as soon as possible, to prevent additional damage to other parts,
as follows: (see fig. 21)
1. Remove the big-end pin (8) and nut (9) on both sides of the crank bearing (5) so
that both crank elements (3 & 6) become loose.
2. Next, remove the rings and nuts (1 & 2) on both sides of the crank elements (3 &
6).
3. Remove both crank elements (3 & 6).
4. Remove the two spacers (4).
5. Remove the profile shaft (7) with bearing (5).
6. Remove the bearing (5) of the profile shaft (7).
7. Replace the parts and assemble in the reverse order.
@ Use Loctite for nuts (2 & 9). Tighten the nuts with the moment that is shown in
fig. 22.
