Camshaft - LH: Installation

WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty and 2013 Ford F-450 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

Lubricate the camshaft and camshaft journals with clean engine oil.
NOTE: Do not remove the Timing Chain Locking Tool at any time during assembly. If the Timing Chain Locking Tool is removed or out of placement, the engine front cover must be removed and the engine must be retimed. For additional information, refer to TIMING DRIVE COMPONENTS .

NOTE: Do not allow the roller followers to move out of position when installing the camshaft.

Install the camshaft into the camshaft sprocket assembly and onto the head. Install a new camshaft sprocket bolt finger-tight.

NOTE: Do not remove the Timing Chain Locking Tool at any time during assembly. If the Timing Chain Locking Tool is removed or out of placement, the engine front cover must be removed and the engine must be retimed. For additional information, refer to TIMING DRIVE COMPONENTS .

NOTE: The timing chain must be installed in its original position onto the camshaft sprocket using the scribed marks, or damage to valves and pistons will result.

Verify the camshaft sprocket and timing chain scribe marks are still in alignment.

NOTE: Do not allow the roller followers to move out of position when installing the camshaft.

Install the camshaft bearing caps in their original locations.
- Lubricate the camshaft bearing caps with clean engine oil.
- Position the front camshaft bearing cap.
- Position the remaining camshaft bearing caps.
- Install the 12 bolts loosely.
Tighten the 12 LH camshaft bearing cap bolts in 2 stages:
- Stage 1: Tighten to 8 Nm (71 lb-in) in the sequence shown in the illustration.
- Stage 2: Tighten an additional 45 degrees.

NOTE: Do not allow the valve keepers to fall off the valve or the valve may drop into the cylinder. If a valve drops into the cylinder, the cylinder head must be removed. For additional information, refer to CYLINDER HEAD .

NOTE: It may be necessary to push the valve down while compressing the spring.

NOTE: Lubricate the camshaft roller followers prior to installation.

Using the Valve Spring Compressor, install the 4 originally removed camshaft roller followers.

NOTE: Only use hand tools to install the camshaft sprocket assembly or damage may occur to the camshaft or camshaft sprocket.

NOTE: Damage to the camshaft sprocket assembly will occur if mishandled or used as a lifting or leveraging device.

Tighten the camshaft sprocket bolt in 2 stages:
- Stage 1: Tighten to 40 Nm (30 lb-ft).
- Stage 2: Tighten an additional 90 degrees.
