Features: This tool is suitable for BMW M60 M62 Land Rover Range Rover 4.4 V8 engine, The chain tensioning bracket trestle is used to provide installation points for rigid chain tensioning tools, At the same time, remove the front timing gearbox from the engine to repair the timing chain or maintenance Repair the VANOS components and adjust the cam timing. Convenient operation, saving time and effort. Suitable for the following models: A: Exhaust camshaft fixing tool 1-4 cylinders (right cylinder group) B: Intake camshaft fixing tool 1-4 cylinders (right cylinder group) C: Intake camshaft fixing tool 5-8 cylinders (left cylinder bank) D: exhaust camshaft fixing tool 5-8 cylinders (left cylinder group) E: BMW camshaft sensor fixing tool (right cylinder bank) F: BMW camshaft sensor fixing tool (left cylinder bank) G: Solenoid valve sleeve of variable camshaft timing control system H: Chain tensioning and fixing tool (used with L) l: 2 secondary tension pins J: Variable camshaft timing control system adjustment tool K: E54-X5 and Land Rover Range Rover 4.4 flywheel fixing tool L: Camshaft sprocket tensioning tool M: M60 M62 flywheel fixing tool. Description-check time Note: These instructions are for reference only. Please refer to the vehicle manufacturer's instructions or Other such reputable data providers. Rotate the engine only in the forward direction, set the engine as the first cylinder of TDC, And insert the appropriate flywheel locking tool. Ensure that the cam lobe of the first cylinder is shown in Figure 1, and check whether the engine is in position At TDC No. 1. As shown in Figure 1 Now install (A, B, C and D) camshaft locking tools, as shown in Figure 2. (A and B = right cylinder, C&D = left cylinder) When engaging the camshaft, make sure that the components (A, B, C and D) are flush with the cylinder head level. There is a "hexagonal" part on the camshaft, allowing the use of a wrench to rotate Camshaft to ensure that the components (A, B, C and D) are flush. Note: Use the hexagonal part to hold the camshaft to resist looseness or tighten the cam Any torque applied by the shaft pulley. Do not use components (A, B, C, and D) to bear these loads. , The engine oil pan can now be removed according to the manufacturers instructions and removed Timing chain and sprockets. When pre-tensioning the main timing chain, please make sure to use it on a non-VANOS engine. Component (L), and use (L) and (H) on the VANOS engine The main chain is pre-tensioned. If you remove the drive chain, push the tensioner back and install the secondary chain tensioner Tensioner pin (I). Engine equipped with VANOS Note: Camshaft nuts and screws have left-hand threads Auxiliary cam chain tensioner- When reinstalling the cam chain on an engine equipped with VANOS, BMW recommends Use a multimeter to set for continuity and connect to the contact pin of the camshaft adjuster And the screws on the cylinder head, upper oil pipe, as shown in Figure 3. Use component J to rotate the cam counterclockwise using a torque wrench set to 40Nm Shaft fixing device. Turn the pulley fixing nut until the multimeter buzzer It sounds to indicate that the camshaft adjuster has been set. Now, tighten the camshaft skin The fixing bolt of the pulley. Repeat for both cylinder banks.
