Illustration 3 g01024862 - Install Tooling (B) on front housing (7). Do not tighten the bolts that hold Tooling (B) to front housing (7) at this time.
- Use Tooling (H) to align Tooling (B) with the camshaft bearings. Tighten the bolts that hold Tooling (B) to front housing (7). Remove Tooling (H).
Note: Tooling (H) should move freely from the bore of Tooling (B).
Show/hide tableIllustration 4 g00581445 - Install Tooling (C) in the end of camshaft (8).
Note: Rotate the camshaft during installation. This will prevent the camshaft from binding in the camshaft bearings.
- Use a suitable lifting device in order to position camshaft (8) into Tooling (B) and the cylinder head. The weight of the camshaft is approximately
39 kg (86 lb) .Show/hide tableIllustration 5 g00581444 Show/hide tableIllustration 6 g00581443 Note: Tooling (C) must be removed before the camshaft can be completely installed in the cylinder head.
- Remove the lifting device. Rotate the camshaft during installation. Use care not to allow the end of the camshaft and Tooling (C) to drop. Use Tooling (D) to assist in aligning camshaft (8) with the camshaft bearings.
- Remove Tooling (C) and finish installing camshaft (8) in the bore.
- Remove Tooling (A) and Tooling (B).
