Oil Pump: Installation

WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

Rotate the inner rotor of the oil pump assembly to align the flats on the crankshaft and slip the oil pump over the crankshaft until seated against the block.
- Rotate the oil pump until the bolt holes are aligned to the block and install the fasteners.
NOTE: Oil pump must be held against the cylinder block until all bolts are tightened.

Tighten the fasteners in the sequence shown below in 3 stages:
- Stage 1: Hand tighten.
- Stage 2: Tighten the bolt (1) to 10 Nm (89 lb-in), the stud bolt (2) to 25 Nm (18 lb-ft), the bolt (3) to 10 Nm (89 lb-in) and the stud bolt (4) to 20 Nm (177 lb-in).
- Stage 3: Tighten the bolt (1) an additional 45 degrees, the stud bolt (2) an additional 75 degrees, the bolt (3) an additional 45 degrees and the stud bolt (4) an additional 60 degrees.

Install the oil pump screen and pickup tube. For additional information, refer to ENGINE LUBRICATION COMPONENTS - EXPLODED VIEW and OIL PUMP SCREEN AND PICKUP TUBE .
Install the crankshaft sprocket with the flange facing forward.
Install the LH primary timing chain.
- Align the colored link on the timing chain with the timing mark on the LH VCT assembly.
Align the remaining colored link on the timing chain with the timing mark on the crankshaft sprocket.
NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the LH timing chain guide. Return the crankshaft keyway to the 9 o'clock position after installing the LH timing chain guide.

Install the LH timing chain guide and bolt.
- Tighten to 10 Nm (89 lb-in).
NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the LH timing chain tensioner arm. Return the crankshaft keyway to the 9 o'clock position after installing the LH timing chain tensioner arm.

Install the LH timing chain tensioner arm.

NOTE: Complete the following 3 steps on both the LH and RH primary timing chain tensioners.
NOTE: Do not compress the ratchet assembly or damage to the tensioner will occur.

Compress the primary timing chain tensioner plunger, using an edge of a vise.
Using a small screwdriver or pick, push back and hold the ratchet mechanism, then push the ratchet arm back into the tensioner housing.
Install a suitable pin into the hole of the tensioner housing to hold the ratchet assembly and plunger in place during installation.
Install the LH primary timing chain tensioner and 2 bolts.
- Tighten to 10 Nm (89 lb-in).
- Remove the holding pin from the tensioner.
Using the crankshaft holding tool, rotate the crankshaft clockwise until the crankshaft keyway is at the 12 o'clock position.
Install the RH primary timing chain.
- Align the colored link on the timing chain with the timing mark on the RH VCT assembly.
Align the remaining colored link on the timing chain with the timing mark on the crankshaft sprocket.
NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the RH timing chain guide. Return the crankshaft keyway to the 12 o'clock position after installing the RH timing chain guide.

Install the RH timing chain guide and bolt.
- Tighten to 10 Nm (89 lb-in).
NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to install the RH timing chain tensioner arm. Return the crankshaft keyway to the 12 o'clock position after installing the RH timing chain tensioner arm.

Install the RH timing chain tensioner arm.
Install the RH primary timing chain tensioner and 2 bolts.
- Tighten to 10 Nm (89 lb-in).
- Remove the holding pin from the tensioner.
With the crankshaft keyway still at the 12 o'clock position, verify the timing mark alignment is correct.
