D) Install the connecting rod cap respecting numbering, and fasten the relevant bolts (lubricating both the
head and the threaded stem) proceeding in three different steps, see fig. 7.
1. Approaching torque 4-6 ft. lbs. (6-8 Nm)
2. Pre-fastening torque 18-20 ft. lbs. (25-28 Nm)
3. Fastening torque 28 ft. lbs. (38 Nm)
E) After setting the torque, check that the big end of the connecting rod has a lateral play in both directions.
F) Install thr rear cover positioning the oil dipstick hole upward.
G) Fill the crankcase with oil as indicated in the owner’s manual paragraph 7.4
2.1.3 Disassembly / Assembly of bearings and shims
The type of bearings used (taper roller bearings) ensures the absence of axial play on the crankshaft; the
shims are to be determined to reach this purpose. Tp disassemble/assemble, or to replace them if needed,
carefully follow the instructions below.
A) After removing the side covers, as indicated in paragraph 2.1.1, check the rollers and their faces for wear;
if all parts are in good condition, accurately clean the components with a suitable degreaser and grease
them again evenly using the same oil used in the crankcase.
The same shims can be used again, being careful to fit them under the cover on the sight glass side. After
installing the complete unit (sight glass flange + shaft + engine side flange), check that the shaft’s rolling
torque - with the connecting rods free - is a least 3 ft. lbs. (4 Nm), max 4 ft. lbs. (6 Nm). To position
the two side covers on the crankcase, initially use 3 screws, M6 x 40 as shown in fig. 6, and then
fastening the screws.
The shaft’s rolling torque (with the connecting rods coupled) must not exceed 6 ft. lbs. (8 Nm).
