Tightening conditions
Bolts 740.1005157-02 for main bearing caps (vertical) of the crankshaft
The bolt threads must be lubricated with engine oil, excess oil must be removed.
Tighten to produce, from the middle support to the extreme ones, starting from the right row in 2 steps:
- - pre-torque 95-120 Nm (9.6-12 kgf-m);
- - final torque 275-295 Nm (28-30 kgf-m).
Coupling bolts 7482.1005158, 7482.1005159 crankshaft bearing caps
The threads in the holes of the cover and on the bolts must be lubricated with engine oil, excess oil must be removed.
Tighten to 147-167 Nm (15-17 kgf-m).
Flywheel bolts
Before screwing in, the threads must be lubricated with a thin layer of graphite grease.
Tightening should be carried out sequentially in two steps (preliminary and final), finally with a torque:
- 7406.1005127 - 245...264 Nm (25...27 kgf-m).
- 740.1005127-11 -167...186 Nm (17...19 kgf-m).
Bolts for fastening the half-coupling of the power take-off and damper 740.21-1005106-10 or 740.1005106
Immediately before assembly, apply Stopor-6 sealant according to TU 2257-003-25669359-98 or Unigerm 6 according to TU 6-01-1285-84 on 3-4 threads of the bolt thread with complete filling of the thread profile using the method dipping or brush. The thread surface must be clean, free of oil and corrosion.
Tighten to 98-117.6 Nm (10-12 kgf-m).
Connecting rod cap bolt 740.1004062-11
Tighten in 2 steps:
- - pre-set with an initial torque of 76.5-80.4 Nm (7.8-8.2 kgf-m);
- - finally, controlling 2 parameters, the nut rotation angle equal to -50°±5° from the position after pre-tightening and the torque value 108-180 Nm (11-18.3 kgf-m). In this case, the control of the angle of rotation of the nut is decisive.
A tightening torque of 127.5-137.3 Nm (13-14 kgf-m) is allowed.
