3508 Engine Only
NOTE: Before the flywheel housing is removed, the 3508 engine must be put in time to make sure the rear gear group is in alignment according to the rotation of the engine as shown.
1. Remove plate (1) and gear assembly (2).
2. Use tool group (A) and a press to remove bearing (3) from gear assembly (2).
3. Use tool group (A) and a press to make a separation of the gears in gear assembly (2).
4. Remove the bolts, the shafts, gears (4) and the washers.
5. Remove washers (6) and shafts (5) from gears (4).
6. Use tool group (A) and a press to remove the bearings from gears (4).
7. Remove shaft (7).
8. Remove the bolts and gear (8) from the end of the crankshaft.
NOTE: The following steps are for installation of the rear gear group.
9. Put gear (8) in position on the end of the crankshaft, and install the bolts.
10. Install shaft (7).
11. Use tool group (A) and a press to install the bearings in both gears (4) until the bearings are in the center of the gears. The bore in the bearing must be 75.000 ± 0.053 mm (2.9531 ± .0021 in) after installation.
12. Put clean engine oil on the bearing, and install shafts (5) in gears (4). Install washers (6) on the shafts.
13. Put gears (4) in position on the cylinder block, and install the bolts to hold the gears in position. Tighten the bolts to a torque of 135 ± 15 N·m (100 ± 11 lb ft).
14. Use tool group (A) and a press to install bearing (3) in gear assembly (2). The bore in bearing (3) must be 75.000 ± 0.053 mm (2.9531 ± .0021 in) after installation.
NOTE: For a 3508, make sure the joint in bearing (3) is in the center of the heavy section of gear (2).
15. Heat the larger gear of gear assembly (2) to a maximum temperature of 400°C (752°F), and install it on the smaller gear.
NOTE: For a 3508, make sure the marks on gear assembly (2) and gear (8) are in alignment according to the rotation of the engine. See the Specifications Manual.
16. Put clean engine oil on bearing (3) and install gear assembly (2) on shaft (7).
17. Put plate (1) in position on gear assembly (2) and install the bolts.
