Camshaft Gear

Start replacement of the exhaust camshaft position actuator by taking off the camshaft cover. Align the word delphi from the exhaust camshaft position actuator with the Cylinder Head to cam cover mating surface when the engine reaches its parallel position. Start by using the point of reference on the exhaust camshaft position actuator sprocket for marking the associated Timing Chain link. Secure the Timing Chain retention tool (J 44217) by inserting the hook hooks into Timing Chain links around the shoes on engine sides prior to tightening the wingnuts until the hooks remain secure with gauge blocks attached to each head edge. The procedure requires removal of both the exhaust camshaft position actuator bolt followed by the separation of the actuator itself. When installing the exhaust camshaft actuator place it within the Timing Chain system while guiding its marked link to match the sprocket timing mark along with proper alignment pin insertion. The installation of the actuator must follow proper location placement for fasteners while the actuator needs to be fully advanced during installation to safeguard the engine from damage. Torque the camshaft actuator bolt with a clockwise rotation relatively to the camshaft until secure. You must first tighten the exhaust camshaft actuator bolt to 25 nm (18 lb ft) before using the torque angle meter (J 36660-A) to finish turning it by 135 degrees. After removing the Timing Chain retention tool (J 44217) users must install the top chain guide then apply threadlocker to the top chain guide bolt threads before securing the bolts to 10 nm (89 lb in) torque specification. Finally, reinstall the camshaft cover.

The first task for camshaft intake sprocket replacement requires camshaft cover removal. cek the rotation of the Crankshaft in a clockwise direction for the #1 Piston to pass tdc while located on compression stroke. Position the timing mark from the intake camshaft sprocket onto the following Timing Chain link for marking. Fasten the camshaft holding tool (J 44221) at the back end of the camshafts. Securely position the Timing Chain retention tool (J 44217) along with the chain holding tool (J-44217-45) through their hooks into Timing Chain links near Timing Chain shoes both at the front and back engine sides while tightening wingnuts until the hooks remain firmly in position and gage blocks stay secure. First remove and throw away the intake camshaft sprocket bolt before you uninstall the intake camshaft sprocket. To install the new intake camshaft sprocket begin by positioning its timing mark directly with the marked link of the Timing Chain. Use a new bolt to secure the new intake camshaft sprocket onto the intake camshaft while tightening it with 20 n.m (15 lb ft) torque and 100 degrees additional angle meter (J 45059) measurement. The last step requires you to take off the camshaft holding tool (J 44221) and chain holding tool (J-44217-45) as well as the Timing Chain retention tool (J 44217) before putting back the camshaft cover.

Before replacing the intake Camshaft sprocket obtain en-44217-45 (Chain Holding Tool) combined with j 44217 (Timing Chain Retention Tool) together with j 44221 (Camshaft Holding Tool) and j 45059 (Angle Meter). The first step requires removal of both the Camshaft cover as well as the intake Camshaft position (CMP) sensor. The #1 piston should reach top dead center on its compression stroke while the Crankshaft rotates clockwise until the exhaust Camshaft position actuator has delphi markings facing parallel to the cylinder head to cam cover mating surface. Use a marker to indicate the Timing Chain link directly next to the timing mark position on the intake Camshaft sprocket. To begin installation start with the j 44221 (Camshaft Holding Tool) on the camshafts backside while the j 44217 (Timing Chain Retention Tool) and en-44217-45 (Chain Holding Tool) go around a Timing Chain link near the Timing Chain shoe locations on both engine sides. Secure the wing-nuts after hooking in the tools. Thoroughly inspect and clean the intake Camshaft sprocket after removing it together with the sprocket bolt which needs to be discarded. The installation begins by guiding the marked link on the Timing Chain towards the timing mark of the new intake Camshaft sprocket with a 25 mm (1 inch) wrench fastened to the Camshaft hex. Attach the new intake Camshaft sprocket to its bmw mount and secure it with the new intake Camshaft sprocket bolt at 20 nm torque while rotating the bolt 100 degrees using the j 45059 (Angle Meter). The procedure ends by removing tools j 44217 and en-44217-45 and j 44221 before reinstalling the intake cmp sensor and replacing the Camshaft cover.

The procedure to replace the camshaft intake sprocket begins by removing the camshaft cover then rotating the Crankshaft clockwise until the #1 Piston arrives at top dead center (TDC) compression phase with the word delphi on the exhaust camshaft position actuator directed parallel to the Cylinder Head to cam cover mating surface. The timing mark on the intake camshaft sprocket establishes a guide for marking the adjacent section of Timing Chain. Position the camshaft holding tool (J 44221) at the rear of the camshafts before using the Timing Chain retention tool (J 44217) along with the chain holding tool (J-44217-45) to secure Timing Chain links near both engine sides by tightening wingnuts for stable gage blocks placement on the head edge. Start by removing and discarding the intake camshaft sprocket bolt before departing with the intake camshaft sprocket. To install properly position the marked Timing Chain link with the intake camshaft sprocket timing mark. Then use a 25 mm wrench on the camshaft hex and ensure the alignment pin snaps into place. Use the angle meter (J 45059) to tighten the new intake camshaft sprocket bolt until it reaches 20 n.m (15 lb ft) and an additional 100 degrees. Finish the procedure by taking out both timing tools named Timing Chain retention tool (J 44217) and chain holding tool (J-44217-45). Remove the camshaft holding tool (J 44221) then install the camshaft cover.

The replacement process of the intake camshaft sprocket begins with camshaft cover removal. Before beginning the procedure rotate the Crankshaft clockwise while the #1 Piston moves to top dead center (TDC) compression position to achieve this orientation where "delphi" on the exhaust camshaft position actuator faces parallel to the Cylinder Head to cam cover mating surface. The adjacent Timing Chain link receives positioning marks from the intake camshaft sprocket timing mark as a starting point. Fit the camshaft holding tool (J 44221) at the back of the camshafts. Fasten the Timing Chain retention tools (EN-44217-45) by hooking their ends into nearby Timing Chain links at both engine sides until the wing-nuts reach maximum tightness while keeping the hooks embedded and gage blocks pressed against the head edges. Before cleaning the item remove and discard the intake camshaft sprocket bolt while also taking off the intake camshaft sprocket. During installation position the marked link on the Timing Chain to match the timing mark on the intake camshaft sprocket by using a 25 mm (1 inch) wrench on the hex of the camshaft for alignment. Place the intake camshaft sprocket on its respective location before tightening a new intake camshaft sprocket bolt to 20 nm (15 ft. Lbs.). The angle meter (J 45059) needs to be used for rotating the intake camshaft sprocket bolt by 100 degrees. Put away the Timing Chain retention tools (EN-44217-45) together with the camshaft holding tool (J 44221) before returning the camshaft cover to its position.

Remove the Timing Chain Retention Tool (J 44217) and install the top chain guide.

Install the Camshaft Holding Tool (J 44221) at the rear of the camshafts, then install the Timing Chain Retention Tool (J 44217) and Chain Holding Tool (J-44217-45) by hooking them into a timing chain link near the timing chain shoe on both sides of the engine, tightening the wingnuts while ensuring the hooks remain in place.

Mark the adjacent timing chain link using the timing mark as a reference.

Install the J-44221 (Camshaft Holding Tool) to the rear of the camshafts.

Ensure the word Delphi on the exhaust camshaft position actuator is parallel with the cylinder head to cam cover mating surface.

Rotate the crankshaft clockwise until the #1 piston is at top dead center (TDC) on the compression stroke.

First, remove the camshaft cover.

Install the actuator onto the exhaust camshaft.

Remove and discard the intake camshaft sprocket bolt.

Use the timing mark to mark a timing chain link across from it.
