Notice: Refer to Fastener Notice in the Preface section.
Important:
• | The crankshaft balancer is balanced as an individual component. It is not necessary to mark the balancer prior to removal. |
• | The crankshaft balancer installation and bolt tightening involves a 4 stage tightening process. The first pass ensures that the balancer is installed completely onto the crankshaft. The second, third and fourth passes tighten the NEW bolt
to the proper torque. |
• | The used crankshaft balancer bolt is used only during the first pass of the balancer installation procedure. Install a NEW crankshaft balancer bolt and tighten as described in the second, third and fourth passes of the balancer bolt tightening procedure. |
• | Ensure the teeth of the tool engage the engine flywheel teeth. |
- Install the
EN 47699
(2), spacer (1), and bolt (3) to the block and flywheel.
- Tighten the
EN 47699
bolt (1).
Tighten
Tighten the bolt to 60 N·m (44 lb ft).
Important: The balancer should be positioned onto the end of the crankshaft as straight as possible prior to tool installation.
- Position the balancer (138) onto the end of the crankshaft.
- Use the
J 41478
and the
J 41665
in order to install the balancer.
4.1. | Assemble the
J 41478
threaded rod, nut, washer and
J 41665
installer. |
Insert the smaller end of the installer into the front of
the balancer.
4.2. | Use a wrench and hold the hex end of the threaded rod. |
4.3. | Use a second wrench and rotate the installation tool nut clockwise until the balancer is started onto the crankshaft. |
4.4. | Remove the tool and reverse the installation tool. |
Position the larger end of the installer against the front of the balancer.
4.5. | Use a wrench and hold the hex end of the threaded rod. |
4.6. | Use a second wrench and rotate the installation tool nut clockwise until the balancer is installed onto the crankshaft. |
4.7. | Remove the balancer installation tools. |
- Install the used crankshaft balancer bolt (139).
Tighten
Tighten the crankshaft balancer bolt to 330 N·m (240 lb ft).
- Remove the used crankshaft balancer bolt (139).
Important: The nose of the crankshaft should be recessed 2.4-4.48 mm (0.094-0.176 in) into the balancer bore.
- Measure for a correctly installed balancer.
If the balancer is not installed to the proper dimensions, install the
J 41665
and repeat the installation procedure.
- Install the NEW crankshaft balancer bolt.
Tighten
- Tighten the crankshaft balancer bolt a first pass to 50 N·m (37 lb ft).
- Tighten the crankshaft balancer bolt a second pass to 140 degrees using the
J 45059
.
- Remove the
EN 47699
, spacer, and bolt.
