Instructions

Preparation:

Raise vehicle
Remove the under shield
Remove engine top cover
Remove cam cover
Remove sump
Ensure the engine is positioned at TDC No. 1 cylinder

Item A: Specifically designed to fit the BMW N51/ N52/ and N55/S55 engines; it is designed to be used to lock both camshafts in their timed positions as shown in Fig. 1. Ensure the engine is at TDC with Item E in place.

Item B: The VANOS sensor alignment tool is double-sided with clear markings to distinguish between engine applications. When fitting, ensure that the two locating pins enter into the holes in the VANOS units (refer to Fig. 2).

Item C: Fitted and used in the same way as Item A but is specific to the N53 and N54 engines.
Item D: Designed to pre-tension the timing chain tensioner.
Item E: This tool is used to lock the flywheel in position and thereby lock the crankshaft in the TDC No. 1 cylinder position (refer to Fig. 3).

Safety Warnings – please read

If the engine has been identified as an Interference engine, damage to the engine will occur if the timing belt has been damaged. A compression check of all the cylinders should be taken before the cylinder head (s) are removed.
Do not turn the crankshaft or camshaft when the timing belt/chain has been removed.
To make turning the engine easier, remove the spark plugs/glow plugs or injectors.
Observe all tightening torques.
Do not turn the engine using the camshaft or any other sprocket.
Disconnect the battery earth lead (check Radio code is available).
Do not use cleaning fluids on belts, sprockets, or rollers.
Some toothed timing belts are not interchangeable. Check the replacement belt has the correct tooth profile.
Always mark the belt with the direction of running before removal.
Do not lever or force the belt onto its sprockets.
Do not use timing pins to lock the engine when slackening or tightening the crankshaft pulley bolts.
ALWAYS REFER TO A REPUTABLE MANUFACTURER’S WORKSHOP MANUAL.
