Camshafts RH






Camshaft RH
This is a "Trustmark Authoring Standards (TAS) Repair Procedure"
- TAS style procedures can be identified by steps that have no accompanying step text and the magenta color of the electrical connectors and fasteners such as nuts, bolts, clamps or clips.
- TAS removal and installation procedures use a sequence of color illustrations to indicate the order to be followed when removing/disassembling or installing/assembling a component.
- Many of the TAS procedures will have the installation information within the removal steps.
- The TAS color illustrations use a variety of symbols to indicate important details of the procedures. It is important to understand these symbols in order to properly used the TAS procedures.
Refer to How to Use TAS Procedures and TAS Symbol Glossary at Vehicle | Description and Operation for additional information on these TAS procedures.

Removal

CAUTION: Make sure that the orientation and code on the top of the camshaft bearing caps is noted (along with the bank - A or B), so that on installation the components are installed to their original position. Failure to follow this instruction may cause damage to the vehicle.

NOTE:
Removal steps in this procedure may contain installation details.

NOTE:
Some variation in the illustrations may occur, but the essential information is always correct.
For additional information, refer to Specifications Battery and Charging System

WARNING: Make sure to support the vehicle with axle stands.
1 Raise and support the vehicle.
For additional information, refer to Timing Drive Components Service and Repair





CAUTION: Rotate the camshafts until all the valves are at their minimum open point.

CAUTION: Evenly and progressively, release the camshaft bearing caps.

NOTE:
Remove the camshaft bearing caps. Note: their position, orientation and markings. Each is marked with its position (number) and an orientation (arrow).

Installation






CAUTION: Prior to installing the camshafts, position the crankshaft 45 degrees ATDC cylinder 1A to prevent valve/piston collision.

CAUTION: Evenly and progressively install and tighten the camshaft bearing caps.

CAUTION: Make sure that the camshafts and camshaft bearing caps are installed in their original locations.

NOTE:
Lubricate the camshafts and the camshaft bearing caps with EP90 oil (or 75/90 viscosity oil will suffice) prior to installation.

Torque to: 3 Nm





NOTE:
Tighten the bolts in the indicated sequence.

Torque to: 12 Nm

CAUTION: Only rotate the crankshaft clockwise.
1 Rotate the crankshaft until the camshaft lobe on the valve being checked is 180 degrees from the maximum opening position.

NOTE:
If the valve clearance is incorrect, continue to the next step. If the valve clearance is correct, continue to step 8.
2 Using feeler gauge check the gap between the tappet and the camshaft lobe and check against specifications table.

CAUTION: Use the following formula to calculate the required bucket thickness. Original thickness + measured clearance - desired clearance = required bucket thickness.

CAUTION: Do not use a magnet to remove the tappet.
3 Remove the tappet and measure the thickness.

NOTE:
If a new tappet is installed then go back to step 1 of the install procedure.
4 Install a new tappet if required.
5 Using feeler gauge check the gap between the tappet and the camshaft lobe and check against specifications table.
