21. Engine
2. Flywheel housing
A. Fitting flywheel housing
The flywheel housing is centred on the cylinder block by two
tension pins. Even the flywheel housings which are delivered
as spare parts have ready ---made holes for the pins.
1. Clean the sealing surfaces between the cylinder block and
the flywheel housing.
2. Apply silicone sealant as shown in figure above.
3. Lift the flywheel housing into place and fit all the bolts.
4. Centre the housing and fit the tension pins with drift 9025
98700.
5. Tighten the fixing bolts, the inner ring socket head bolts to
60 Nm (8.8) or 90 Nm (12.9) and outer ring hexagonal bolts
to 110 Nm (8.8) or 150 Nm (12.9).
B. Changing crankshaft rear oil seal
1. Split the tractor at clutch. Remove the clutch assembly (and
possible turbine clutch).
2. Remove the flywheel.
3. Remove the oil seal. Do not damage the crankshaft.
4. Clean the seal location and grind off any burrs.

Note! If the crankshaft is worn at the sealing location, a 2 mm
spacer ring, part no 8360 20054, can be fitted in front of the
crankshaft rear oil seal.
5. Lubricate the sealing surfaces on the crankshaft and on the
seal. Place the seal on the crankshaft and drive it in until it bot-
toms using drift 9052 46300. Other tools may cause the seal
to be damaged or mounted askew, resulting in leakage.
Note! The cranckshaft rear oil seal has been changed to a
Teflon type. The spare part seals have a mounting sleeve,
which must not be removed before fitting. The spare part
numbers do not change. When fitting the seal, place the plas-
tic sleeve on the crankshaft and push the seal on the sleeve
into place. Remove the sleeve and fit the seal with the special
tool. The seal must be fitted dry.
