NOTICE
Additional application: Locking Pin
3788­21 is also used to check the fuel
pump alignment via holes in two of the
spokes of the pump sprocket. If there is not a da­
tum hole in the pump bracket, behind the sprock­
et, to accept the Locking Pin, then align the pump
sprocket position by positioning the holes in the
spokes vertically – one above the other.
• When fitting new timing belt, apply tension by
turning the tensioner roller anticlockwise until
the pointer is positioned between the sides of
the window. Re­fit removed parts and remove
the Locking Pins. Carefully rotate the crank­
shaft 10 times by hand clockwise.

and 3788­23 can be inserted and fuel pump
sprocket is correctly aligned. Re­check the
tensioner pointer is positioned within the win­
dow.
• Insert Locking Pin 3788­22 into the flywheel to
fit the crankshaft pulley, using a new bolt.
