Description
POWERPART Retainer (oil tolerant)
Warning! The flywheel is very heavy, use lift equipment or get assistance with the lift operation before removal
of the flywheel fasteners.
To remove
1 Remove two opposite setscrews from the flywheel and fit temporarily two guide studs to ensure safety when
the flywheel is removed and fitted.
2 Remove the remainder of the setscrews and washers and remove the flywheel.
3 Check the flywheel and ring gear for damage and renew, if necessary.
To fit
1 Ensure that the location faces of the crankshaft and the flywheel are clean and free from damage.
2 Fit temporarily two guide studs in opposite holes in the crankshaft palm to ensure safety when the flywheel
is fitted. Fit the flywheel over the guide studs, ensure that the hole (B1) for the dowel in the crankshaft palm is
in the correct position. Apply POWERPART Retainer (oil tolerant) to the first three threads of the setscrews
and fit four setscrews and their washers. Remove the guide studs and fit the remainder of the setscrews and
the washers. Tighten the setscrews to 105 Nm (77 lbf ft) 10,7 kgf m.
3 Check the flywheel run-out with a dial test indicator (A). This must be less than 0,30 mm (0.012 in) total
indicator reading.
4 Check the alignment of the flywheel face (B). The error in alignment must not be more than 0,03 mm
(0.001 in) total indicator reading for every 25 mm (1.0 in) of the flywheel radius from the crankshaft axis to the
indicator plunger. During this operation, keep the crankshaft pressed toward the front to remove the effect of
crankshaft end-float.
