Installation Instructions

Drive Belt/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.

Procedure:

1. Loosen, but do not remove the lug nuts on the 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. Remove 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 to 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 intermediate shaft pulleys. Tighten the pulley retaining nut to 33 ft/lb.
