Drive Belt/ Pulley Alignment Procedure for G60 models

Note: The following steps assume that the timing belt has slipped during camshaft installation or has otherwise

lost tension below the intermediate shaft pulley. This procedure outlines how to get the motor back into time.

1. Loosen, but do not remove the lug nuts on the of passenger side road wheel. Jack up the

passenger side of the car and support it with a jackstand. Remove road wheel. Remove plastic

inner wheel housing liner/splash shield with an 8mm socket.

2. Loosen the water pump pulley bolts. Loosen the A/C and alternator mounting bolts. Loosen

adjusting screws to provide the slack required to remove the belts. The tensioning mechanism

for the A/C compressor is in the form of a bolt that is part of the mounting bracket itself. Re-

move the water pump pulley and the lower belt.

3. Remove the lower drive belt cover by removing the two nuts and bolt that hold it to the

water pump and front of the motor. Remove all four spark plugs to allow the crankshaft to turn

easier when you adjust it. Set motor to TDC (see step 2 of instructions).

4. Your crankshaft vs. intermediate shaft timing should already be close if you put the motor at

TDC before beginning your cam install. Rotate crankshaft (by hand using a wrench or socket on

the end of the crank) and intermediate shaft until the dot from the intermediate shaft is visible

through the "V" in the crankshaft pulley (fig.1). Caution: Rotate the crankshaft the least amount

necessary align the marks. Since the drive belt is not installed, there may be piston to valve

interference if you try to rotate the crankshaft too much.

5. Check camshaft timing mark, make sure that the dot on the inside of the cam sprocket is

lined up with the camshaft drive belt inner cover (fig 1).

6. Install the camshaft drive belt by sliding it over the sprockets. Start at the crankshaft, then

the intermediate shaft, and finally the camshaft. Try to keep the belt as tight as possible between

the crankshaft and the intermediate shaft, and between the intermediate shaft and the camshaft

sprockets.

7. Using a special spanner wrench (AST P/N 10.012.86400 or equiv.), tighten the drive belt by

rotating the tension pulley in the direction of the arrow (fig. 2). The belt should feel tight when

twisted 90 degrees with the thumb and forefinger, halfway between the camshaft and intermedi-

ate shaft pulleys. Tighten the pulley retaining nut to 33 ft/lb.
