• There are now two types of crankshaft gears
fitted to the Pumpe Düse engine range.
• Use HAZET 2588-1 for 'Round' crankshaft gear,
or HAZET 2588-110 Locking Tool (Gold) for
engines with an 'Oval' crankshaft gear.
ATTENTION:
You MUST ensure that the correct
Crankshaft Locking Tool is used for
the type of Crankshaft Gear fitted.
• The crankshaft is turned clockwise to TDC
position, No.1 cylinder.
• The crankshaft gear is locked in timed position
using the Crankshaft Locking Tool applicable
to the type of Crankshaft Gear fitted to the
engine.
• The tool locates into the gear teeth and at the
same time into the hole in the oil seal housing.
The tool slides into the gear teeth from the
front face of the crankshaft gear. It cannot
locate correctly if only placed directly on to
the top of the gear.
CAUTION:
The timing mark "arrow" on the Crankshaft
Locking Tools MUST align with the timing
mark on the crankshaft gear. If the
incorrect tool has been selected, the timing marks
will not align.
Temporarily remove the plastic knob off
2588-1 Tool to improve visibility of the timing
marks.
• The engine must be positioned at TDC BEFORE
the tool is fitted. If the engine is turned passed
the TDC position, turn the crankshaft back ¼
turn and then forward again to insert the Tool.

ATTENTION:
ENGINE MOUNTING (REMOVAL)
– BELT TENSIONING:
Check if Engine Support is "Large"
or "Small" type of engine mounting
From June 2005 some models have a modified
"Larger" engine mounting fitted.
These larger engine mountings avoid having to
remove the mounting and support the engine from
below, when removing the timing belt .
Therefore as the Engine Mountings remain in
place:-
Use NEW UPDATE TOOLS
and 2588-18, in Hazet Update Set 2588/9 for
tensioning the belt.
Timing Belt Tensioning

• Ensure the crankshaft is 'locked' with correct
Crankshaft Locking Tool and Locking Pins are
inserted through the camshaft sprockets.
• Loosen the camshaft sprocket bolts so the
sprocket(s) can be moved within the elongated
holes, but not tilt.
• Slacken the tensioner nut and using HAZET
2588-17 Adjuster turn the tensioner anti-
clockwise until HAZET 2588-18 Locking Tool
can be inserted.
• Turn the tensioner fully clockwise until it
reaches the stop and tighten pulley nut.
Remove the old timing belt.
ATTENTION:
Ensure that the tensioner retaining "lug"
is fully engaged. (Seated properly in the
rear toothed belt guard).
• Turn the camshaft sprockets(s) clockwise in
the elongated holes and fit the new timing belt
commencing at the crankshaft gear.
• Slacken the tensioner nut and remove HAZET
2588-18 Locking Tool. Now turn the tensioner
clockwise until the tensioner pointer is aligned
with the 'notch' in the back plate.
CAUTION:
Tensioner pulley nut must not be allowed
to turn. Restrain movement of the
tensioner using the Tensioner Adjuster
and tighten pulley nut
